A unique analogue take on granular synthesis, inspired by Yannis Xenakis, the Grainity pairs a granular filter with a multimode filter to create new textures and harmonics.

Supplier's Notes:
The Grainity brings a unique and never-heard-before concept to the world of analogue VCF.

While being based on analogue filtering only, the Grainity expands and enriches the sound in creating subharmonics, harmonies, unison, flanging effects and formant filtering all at once.

The module presents two sections, the granular filter itself and a typical multimode filter, each with its own output.

A third output offers a mix of both filter paths. Numerous controls and CV allow a very wide palette of results.

What is the Grainity

Granular?

The word granular was chosen for this filter module in relation to the concept invented by the composer Yannis Xenakis, and which is described as assembling small chops of sounds - he called grains - according to a pattern.

This is exactly what the Grainity does, no more no less ... but, digital control allows doing it in ways that are decades away from what tape and scissors allowed at the time.

Technology wise ...

In the granular section, the incoming sound cycle is determined in order to step through various filtering and phase variations of itself according to predefined patterns called structures.

The controls allow alterations to the cycling phase, cycling frequency offset (tuning), structure selection and frequency division of the filters cycling. This comes in addition to the usual filter frequency and resonance controls.

What the Grainity is not

Technology wise ...

Despite relying on a microprocessor, the Grainity is not a digital audio processor. At any time, the sound remains in the analog domain and goes through analog circuits from in to out.
The digital processor does not convert or generate audio signals; it is there to control the analog circuitry and manage the interface and display.

Sound wise ...

Several digital modules offering granular processing rely on the layering of sound grains, which leads to blurry and cloudy textures.
Layering of the grains is a late addition to the concept of granular synthesis and is not a mandatory feature of the concept.
The Grainity does not use delay lines or sampling memory but is nevertheless true to the foundations of the granular synthesis concept.

The granular VCF in the Grainity is unconventional in that, most of times, it is not filtering the sound in the common expectation of removing something. Typically, the granular process adds more than it removes by expanding both the lower range, creating subharmonics, and the upper harmonic contents in multiples ways.

A characteristically unique take on mixing from Buchla, with six mono inputs and a built-in mic/guitar pre-amp. Each channel can be cued to a monitor mix, while the first and last channels also include voltage-controlled panning.

Supplier's Notes:
The Tiptop 207t is a modern reimagining of the classic Don Buchla 207 Mixer/Preamplifier from the 1970s 200 Series. This stereo mixer comes with a built-in preamp that allows you to boost external instruments and microphones, making it a versatile tool for any modular setup. The 207t also features a six-channel mixer with a variety of signal routing options, including the ability to route channels to the monitor and L&R signal outputs, with per-channel control over loudness and panning.

Each channel has a Mon switch that sends the channel's signal to the monitor outputs, which are always full-volume and summed to mono, making it useful for basic monitoring applications or rudimentary mixing. The Prog switch sends the signal to the L&R signal outputs, with loudness controlled by the Level Adjustment slider and panning determined by the Channel Assignment knobs. The first and sixth channels offer voltage control of panning; these channels are hard-panned when no CV is applied.

The preamp section features a 1/4" input and multiple gain settings, making it suitable for use with external line level instruments, electric guitars, or dynamic microphones. The continuous amplification control provides added flexibility for your audio needs. Finally, the Expansion In is a stereo input that sums to the left and right main outputs, which is great for chaining multiple 207t modules or adding another stereo source at the final output.

While the 207t's functionality may be simple, it is an essential part of any 200t system, serving as the glue that holds everything together. The Tiptop 207t is a fantastic mixer/preamp option that delivers quality sound and reliable performance.

The Wave Transformer is a complex single oscillator with 7 audio outputs. Its method of wave shaping differs from other complex oscillators in that it is not based upon classic wave folding such as is common in West Coast synthesis, or filtration such as is common in East Coast synthesis.

This analogue, vintage-voiced, voltage-controlled oscillator features over 8 octaves of accurate pitch tracking. Its 7 simultaneous wave outputs include a unique Complex output. This strange and novel output varies between a simple waveform (triangle, unless you patch a signal into the Shape Insert jack) and a complex transformation of the harmonic structure of the original waveform. It contains a unique mixture of the fundamental frequency, odd order harmonics, even order harmonics and subharmonics. The Sub Octave panel control will determine whether the sub harmonics are derived from one octave down, two octaves down, or are muted altogether. It will vary from a simple waveform to a silhouette of your cat watching you as you react to a "present" that it left for you on the counter. No, seriously.

The module's Transform control morphs from a basic waveform through many strange iterations into a complex, gnarled mass of audio mutations at the Complex output using an asymmetrical multi differential audio transmutation circuit. You can yield countless variations on these permutations by combining this novel circuit with Hard Sync, Soft Sync, Linear FM and Exponential FM.

Additionally, you can mute the source waveform to use the circuit as a harmonic gate/VCA, rendering the Wave Transformer a voice unto itself.

If that is not enough, there is a Shape Insert that allows you to transform external oscillations and modular-level audio sources.

The 'Mega Milton' is a smorgasbord of handy all analogue utilities in just 8HP that will greatly extend the functionality of your Eurorack system.

It includes a stereo line input converter for incorporating line level external sources into a Eurorack system, a fixed 4 input mixer with breakout attenuator for combining signals, a gated slew limiter for adding slides to sequences, a sample and hold with analogue white noise with a myriad of uses such as generative melodies or producing percussive textures and finally a buffered mult for droop free signal distribution with handy LEDs to monitor.

All sections are normalised to help with typical use cases such as generating random CV from the sample & hold section, a smooth random source from the slew output and breaking out a standalone attenuator from the fourth mixer input.

The 'Mega Milton' provides essential classic synthesizer building blocks for patching in any Eurorack system.

Ideal For

Incorporating stereo external sources easily into your Eurorack system.
Signal attenuation and basic mixing in a small space.
Building percussion sounds from an analogue noise source.

Buffering and monitoring voltage across multiple VCOs or other destinations with no drop.

Tech Specs

Supply: +12V 70mA / -12V 70mA
Size: 8HP
Depth: 32mm

Notes: The "uMM" combines a MIDI merger and two independent THRU distributors in a module that is only 4 HP wide. All sockets on the module are in MIDI TRS-B format.

At the heart of the two-input MIDI merger is a small, powerful ARM processor with plenty of buffer memory. Two MIDI streams are mixed to one output and can also be tapped via an additional second output. Two LEDs signal the operation of the merger: one LED indicates MIDI activity at the inputs, and a second LED warns of too much data at the inputs.

The second group of functions consists of two independent, separate MIDI THRU distributors. The MIDI data at the respective MIDI input can be picked up and distributed at the three THRU outputs. If required, a 1-to-5 distributor can be created from the two units by connecting an output of the left group to the input of the right group.

Features:

4x MIDI IN (TRS-B)
2x MIDI-OUT (TRS-B)
6x MIDI-THRU (TRS-B)
Powered via Doepfer connector

Notes: Another banger from ALM. Based on the oscillators from the classic 1980s Casio CZ series, the Cizzle uses phase distortion synthesis for characterful, FM-adjacent synth tones.

Supplier's Notes:
The 'CIZZLE' is a dual digital 'phase distortion' VCO inspired by the classic Casio 'CZ' series synthesizers. It brings the specifics of 'CZ' style phase distortion (PD) synthesis into Eurorack with the inclusion of primary and secondary oscillator layering and detuning (with up to 8 voice chord generation), extended morphable PD wave generation algorithms, unique resonance wave generation, plus specific 'end of chain' ring modulation and noise modes that are key to the CZ sound.

The voices also feature built in VCAs and various modulation controls and inputs, a cv-able chord mode, tracking ability, triggered mode switching and can be output independently or mixed with stereo widening.

The 'CIZZLE' finally brings characteristic CZ style synthesis to Eurorack with a rich palette of sounds from mellow ambient tones, 90s Detroit Techno inspired chords, Reese style basses, and synth tones with unique faux resonance squelch.

Ideal For

Flexible and precise primary digital voice duties in a Eurorack system.

Supplier's Notes:
It's all gone a bit wobbly

Intellijel's design goal for Sealegs was to create the warmest, most musical and organic delay module possible - something that would sweeten and enhance any audio one chose to feed into it. As such, great care has gone into modelling the most distinctive and desirable sonic characteristics of three different types of delay circuits: Tape; Bucket Brigade, and Crossfading Digital.

A plethora of onboard controls enable you to dial in exactly the sound you want; synced or un-synced delays times (for both left and right channels); a built-in modulator with seven morphing waveshapes, a Wow & Flutter emulation, and an envelope follower; plus dedicated low- and high-pass filters; built-in hiss & crackle noises; per-model colour controls; a spacious reverb; and a re-configurable signal flow through the unit. In addition, attenuverted modulation inputs abound - ensuring the delay ebbs and flows with your musical needs.

Features
Three Unique delay models with per-model "Color", modulation behaviour, and saturation/limiting
Three Stereo configurations (PONG, L/R, Time/Width)
Built-in modulator with multiple, morphing wave shapes

Supplier's Notes:
Four channel stereo production mixer

Mixer section

Each channel has the following:

Stereo or mono - Each channel can be treated as a stereo channel or a mono channel with two summed inputs.

CV inputs for both panning and level control

Two send buses - You can route each channel to one of two send buses. Each send bus is stereo. You can choose if you want the send to come before or after the level/panning controls.

Mute - The mute has both latching mute (up) and a momentary mute (down). The mute uses a capacitor to slow the turn off and on of the mute action. So it is mostly click-less, but you may find an occasional pop.

Cue bus - You can route each channel to the cue bus.

Mains Section

Two stereo sends outputs
Two stereo returns - which can also be used to directly insert into the main mix.
Main stereo outputs - level controlled with the slider and stereo VU meter.
Main mono output - summed output of the main L&R. If you are after an 8ch mono mix, you can use each channel in stereo mode, use the level control to control the level and then pan control to control the levels of the two channels.

Cue Section

1/4" Headphone jack along with level control
Fader control to listen to the main mix, cue mix, or an adjustable mix of the two.
Expandable

Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer. The main level is what is sent the main level control can act as a group control.

Barbacks can be added to add 2ch to your mix. Barbacks can also be cascaded enabling up to a 16ch mixer configuration.

Send-VCA can be added for CV control of the level of the send.

DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

Notes: The Dual Stereo Gate (DXG) music synthesizer module is a Dual Stereo Low Pass Gate and Mixer. It follows in the footsteps of the QMMG, Optomix, RxMx, DynaMix, and LxD. Unlike its predecessors, the DXG is specifically oriented around mixing stereo signals, making it an important addition to any system containing modules like XPO, QPAS, Morphagene, Mimeophon, and other stereo modules by Make Noise or others.

Unique to the DXG is a new low pass gate circuit that does not use vactrols. This circuit is 100% analogue and its response was arrived at after many months tailoring it to meet or exceed the expectations that have been set by all the vactrol low pass gates that Make Noise has created over the years.

In the past, Make Noise produced the Dynamix module and Dynamics circuit in the 0-COAST, both of which are vactrolless LPGs; however, the DXG is a completely new approach which better implements the gentle single pole filtering of a low pass gate, while also emulating the slow decay and memory of the vactrol based low pass gate. This new circuit makes possible the consistency of response necessary for versatile stereo use, while also keeping the module small and affordable so that it can be a key part of just about any modular system.

As on all of Make Noise's low pass gates, the DXG's Control parameter is used to set both the amplitude and the frequency content of the sound that passes through it. The control parameter tends to open faster than it closes, imparting a subtle decay phase onto any envelope shape that is used to modulate it.

Unlike previous low pass gates made by Make Noise, all the DXG's inputs and outputs are stereo. Each set of inputs is normalled so that the left input can be used for a mono signal, sending a copy to both left and right outputs. The Auxiliary inputs are also a stereo pair with mono normalization. These normalizations allow for the DXG to be used as a simple three channel stereo mixer, with one or two of the channels additionally being used for dynamics control and note event generation. The Aux inputs can be used to chain together larger decentralized mixes using additional DXG modules, or X-PAN, Optomix, modDemix etc.

Features

- Make Noise's first Stereo Low Pass Gate

- Vactrol-free design for classic Low Pass Gate sounds, but with the balance and consistency needed for true Stereo

- Fully Stereo i/o for easy integration into a Stereo-equipped modular synthesizer

- All Left inputs normalled for easy use with Mono signals

- STRIKE Input allows use of Gate signal to trigger Low Pass Gate circuit, creating "plucking" or "pinging" sound from any Gate

- Summing stage with Stereo AUXiliary IN allows for chaining of multiple units, creating larger mixes

- Part of a decentralized mix console integrated throughout the system along with X-PAN, Optomix, XOH, etc.

- Pairs well with XPO, QPAS, Morphagene, Mimeophon, Spectraphon etc.

Notes: An updated version of the excellent Batumi quad LFO, version II introduces performance updates plus compatibility with the new Poti II expander. Original Poti I breakout functions are now included in the Batumi II.

Supplier's Notes:
Xaoc Devices presents Batumi II - a greatly improved and enhanced new iteration of the modern day classic that is/was the original Batumi, preserving its layout and form factor. The premise remains the same: four LFO's with individual outputs for sine, assign and rectangle waves. The channels can operate independently or they can be linked - phase shifted, divided or multiplied (new mode alert) with regard to the first channel. Multiple major and minor improvements have been implemented, e.g. when synced to an external clock source, each channel's frequency slider selects a clock division for that channel's outputs.

Xaoc Devices have managed to incorporate the features of the original expander into Batumi II (sync mode switching and assign waveform selection) without changing the size of the module which opened up new possibilities for the new optional expander. The Poti II expander for Batumi II adds multi destination inputs for sine wavefolding, assign output waveform selection or rectangle pulse modulation with the destination set for each channel independently. Poti II also features frequency input attenuation as well as sine and assign output attenuation. All adjustments may be performed separately for each individual channel or for all channels simultaneously.

The Batumi II software has been rewritten from scratch to ensure best performance. The hardware has also been updated to allow for V/oct tracking and stable operation up to audio rates (more powerful CPU, precise, wideband converters, antialiased waveforms).

-4 LFO's
- redesigned from scratch - both the hardware and software
- new waveforms for the assign output (including random)
- new frequency multiplication mode
- all features of the Poti expander incorporated into the main module
- very wide frequency range well into audio rate
- 1V/oct tracking = so can be used as 4 VCO's
- in the Phase/Divide/Mult modes the random waves at the ASGN output follow the values available in the master/A channel
- 10HP
- +90/-50mA

Notes: Poti II expander notable features:

- per-channel input and output attenuation for the SINE and ASSGN outputs
- per-channel shape modulation with switchable destination (wave folding, shape switching, PWM)
- stores settings during a power cycle
- LED indication of the discrepancy between the stored setting and current pot position
- 4HP
- +10/-0mA from Batumi II

Notes: Really smart integration of macro controls for Eurorack, based on the original design by Emblematic Systems. Assign settings to eight CV outputs then morph with the crossfader or record movements to manage presets or set up complex real-time modulation. Can also operate as Catalyst Sequencer.

Supplier's Notes:
The Catalyst Controller is a macro controller with eight precision CV outputs and a responsive crossfader to morph between scenes. A scene is a snapshot of up to eight CV outputs, like a modular preset. Traverse a "pathway" composed of multiple scenes using the crossfader or an external CV signal, or immediately jump using the scene buttons. Record CV and slider movements, and play recordings back via a button or external trigger.

Each output has sub-millivolt precision and a maximum range of -5V to +10V. Channels have an adjustable morphing curve, can be quantized to common scales, restricted to a particular voltage range, or set to output gates.

Whether used as a CV preset manager, seamless transition generator, chord sequencer, CV recorder, or experimental CV playground, the Catalyst Controller puts control of your modular at your fingertips.

The Catalyst Controller can also turn into a Catalyst Sequencer! Hold down a special button combination to change between controller and sequencer modes. If you end up liking the Sequencer more, you can even remove the double-sided faceplate, flip it over, and re-install with the Sequencer artwork visible.

Based on the original Catalyst module from Emblematic Systems.

Specifications:

Smooth, responsive crossfade morphs between scenes
Eight output channels, each can be CV or Gate
Arrange scenes into pathways of up to 64 scenes
Smooth, responsive crossfader morphs from scene to scene along the pathway
Set slew/lag to limit how fast scenes can change

Notes: Another update for WMD's clever dual VCA, this time a little bigger to give more control. Digital control of CV and attenuation gives lots of creative options. Third time's a charm.

Supplier's Notes:
WMD have done several designs of this circuit over the years, the first one had no knobs, the second was too small, the MKIII is finally how this circuit should be packaged. This module does some really cool stuff and is super useful in any system.

The Digital VCA lets signal through like a normal VCA, but the CV and attenuation level is controlled digitally. This lets us do things like wait until there is a zero crossing to change the amplitude, resulting in clickless amplitude changes.

The Trigger mode causes the VCA to only update when a trigger is received. The addition of a noise circuit for each side let us do a very quick and easy sample and hold that never droops. With no input, 5V is normaled to the attenuator, so you get a 0-5V sample and hold. In Bipolar mode, you can get -5 to +5V.

Both sides have bipolar VCA mode (polarizer), which lets them invert the signal when negative CV comes in. Also known as ring modulation. With the zero crossing detector, this can produce some super wild wave shapes.

Notes: Based on a new digital hardware platform, the Spectraphon is a powerhouse spectral oscillator, capable of everything from analogue-style dual complex oscillators to FM and much more.

Supplier's Notes:
The Make Noise/Soundhack Spectraphon is a dual Spectral Oscillator coded by Tom Erbe of Soundhack. It uses real-time spectral analysis and resynthesis to create new sounds from those that already exist. It is inspired by classic electronic musical instruments of the past, including spectral processors, additive synthesis, vocoders, and resonators especially the Buchla 296 and Touche, but it takes a physical form more resembling the classic analogue dual complex oscillator in the lineage of the Buchla 259 and the Make Noise DPO.

The Spectraphon is the first module to be built by Make Noise on its new digital hardware platform. This hardware, engineered by Jeff Snyder and Tony Rolando, provides more i/o at higher resolutions, and a lower noise floor than we have ever had access to in a digital module, allowing us to unleash Tom Erbe's DSP code to a previously unattainable degree.

The Spectraphon has two nearly identical sides, A and B, which oscillate in one of two ways: Spectral Amplitude Modulation (SAM), or Spectral Array Oscillation (SAO). In SAM, instead of oscillating at all times like an analogue VCO, sound at the Spectraphon's input is used to modulate the amplitude of a set of harmonics. In SAM the Spectraphon can be sequenced and frequency modulated like any VCO. At any time the current spectrum can be used to create an Array for later use in SAO mode where the Spectraphon oscillates at all times, with the spectrum at the Odd and Even harmonic outputs being drawn from those stored Arrays.

The Slide and Focus controls are mode-dependent: in SAM, they determine how the Spectraphon responds to sound at the input for Spectral AM, while in SAO, they are used to modulate the Array.

In either mode (SAM or SAO), the Partials control works as a combined amplitude and timbre gate for the Odd and Even harmonic output and the FM Bus will create high definition internal frequency modulation from the opposing side of the Spectraphon. The two sides can also interact via the internal FM Bus, the Follow and Sync modes, and by patching them together.

Notes: A characteristically unique take on mixing from Buchla, with six mono inputs and a built-in mic/guitar pre-amp. Each channel can be cued to a monitor mix, while the first and last channels also include voltage-controlled panning.

Supplier's Notes:
The Tiptop 207t is a modern reimagining of the classic Don Buchla 207 Mixer/Preamplifier from the 1970s 200 Series. This stereo mixer comes with a built-in preamp that allows you to boost external instruments and microphones, making it a versatile tool for any modular setup. The 207t also features a six-channel mixer with a variety of signal routing options, including the ability to route channels to the monitor and L&R signal outputs, with per-channel control over loudness and panning.

Each channel has a Mon switch that sends the channel's signal to the monitor outputs, which are always full-volume and summed to mono, making it useful for basic monitoring applications or rudimentary mixing. The Prog switch sends the signal to the L&R signal outputs, with loudness controlled by the Level Adjustment slider and panning determined by the Channel Assignment knobs. The first and sixth channels offer voltage control of panning; these channels are hard-panned when no CV is applied.

The preamp section features a 1/4" input and multiple gain settings, making it suitable for use with external line level instruments, electric guitars, or dynamic microphones. The continuous amplification control provides added flexibility for your audio needs. Finally, the Expansion In is a stereo input that sums to the left and right main outputs, which is great for chaining multiple 207t modules or adding another stereo source at the final output.

While the 207t's functionality may be simple, it is an essential part of any 200t system, serving as the glue that holds everything together. The Tiptop 207t is a fantastic mixer/preamp option that delivers quality sound and reliable performance.

Notes: The Catalyst Sequencer combines a traditional clocked step-sequencer with an unconventional phase-based sequencer to produce a new paradigm in sequencing. Eight precision CV sequencer channels can be simultaneously driven by a clock, a phase CV, or scrubbed manually with the crossfader.

Each of the eight channels has its own sequence length, quantizer, transposition, clock divider, randomization, voltage range (max -5V to +10V), and selectable CV (precise 16-bit resolution) or Gate mode.

Phase-based sequencing is an advanced form of sequencing where each step is selected by CV. The Catalyst Sequencer has a smooth, responsive crossfader that scrubs the sequence, playing it forward or backwards to track your motions. Patching in a CV signal will do the same: a ramp-up CV plays the sequence forwards, a ramp-down plays it backwards, a triangle plays it ping-pong, and complex waveforms generate new interesting rhythmic and melodic patterns.

The Catalyst Sequencer can also turn into a Catalyst Controller! Hold down a special button combination to change between sequencer and macro controller modes. If you end up liking the Controller more, you can even remove the double-sided faceplate, flip it over, and re-install with the Controller artwork visible.

Based on the original Catalyst module from Emblematic Systems.

Notes: A serious bargain for anyone putting together a modular system, TipTop bundle three VCOs and the Octopus controller with their mixer, filter, dual envelopes and VCA. Great value.

Supplier's Notes:
The S2 is a promotional bundle that TipTop is offering to users, providing a 33% savings to get you started with ART. With these bundles, TipTop have included an incredible voice: the big, beefy 3 VCO stack. The bundles come in two options: Bundle S1, which uses the ART V/OCT Quantizer as a controller, and Bundle S2, which uses Octopus as a controller. In addition to the controllers, there are three ATX1 analogue oscillators, MIX7 for mixing them with plenty of headroom, and followed by TipTop's beloved 4-pole Z2040 filter that has been with them since day one; it just sounds so good. Finally, we end up with Control Path dual envelope plus VCA dynamics modules. This special price is time limited and while supplies last.

OCTOPUS is a powerhouse ART controller that takes MIDI in via the USB or DIN connector and outputs 8 ART channels with 8 velocity CV plus 8 drum triggers. Together with the ART oscillators the OCTOPUS provide unprecedented simplicity connecting the modular to your computer sequencers, hardware midi sequencers and keyboards. Each ART channel can play polyphonic notes, monophonic notes or create multi-channel polyphony using an internal voice manager. All together OCTOPUS can play more voices and notes from a single controller than ever was possible in modular. Using ART high speed control signals OCTOPUS can maintain low jitter for tight timing. OCTOPUS is TipTop's first ART controller with more to follow, please select between Octopus or ART V/Oct Quantizer to get started with ART. Please note, OCTOPUS is not a 1V/Oct midi to CV and should not be confused as one.

ATX1: a classic all analogue saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analogue polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. TipTop consider the ATX1 the best sounding analogue VCO they have ever created.

MIX7 is a seven channel analogue summing mixer module for Eurorack. It is designed for summing any of the different types of signals you'll find in a modular system: Audio, CV, Triggers, or Gate.

MIX7 gives ability to sweeten your mix with more headroom using the power of low noise analogue summing. A compact 3HP Eurorack utility module, MIX7 is an attractive mixing addition to any rig, especially with the ability to also combine rhythms, note patterns or CV automations from different control sources. The main output of one section can be connected to the input of another MIX7 to create larger mixing groups and complex signal routes inside your modular.

The MIX7 summing mixing circuit is built with low-noise operational amplifiers, giving it an excellent sound quality for mixing audio, the beautiful texture of classic analogue mixing with plenty of headroom to handle hot modular signals, and the versatility to sum non-audio signals in your system to open up new creative possibilities.
Each input is labelled with a number of dots, 1-7, yellow for input and green for output. The module matches Tiptop's system look with clean white faceplate styling.

At the back of the module is a user-configurable jumper allowing users to configure the MIX7 for either unity gain (OUT = IN) or give increased headroom (OUT = 0.4IN) for use with hot audio signals, which makes it a great pairing for Tiptop Audio percussive modules. A peak indicator light on the front panel warns the user of even the slightest audio clipping in the mix, helping to keep all the incoming sound sources at their full original quality.

CONTROL PATH is an all in one voice dynamics module that helps build full voices quickly. It contains two analogue envelopes with velocity cv, and one VCA. In a typical voice patch the left envelope will control a filter and the right envelope will be the voice VCA. Velocity control is provided for each envelope and delay front panel trimmers are used to compensate for any miss match between incoming gate signal and velocity CV timings. Envelope cv outs are 0-5V, Velocity cv ins are 0-5V.

The Z2040 is TipTop#s redesign of the most famous analog filter from the polysynths of the 80's and features Tiptop Audio's signature lush, big, and creamy sound. Its frequency sweeps make thick bass lines and leads with great dynamics. When modulated with audio frequencies through its various inputs, the Z2040 gets quite colorful and is capable of creating many new sounds and textures as the forces of the incoming waves and their harmonics blend through the filter's non-linear circuit. When set with Resonance feedback fully up, the Z2040 transforms into a pure sine-core VC-Oscillator, great for making snappy percussive elements and whistling sounds.

A look under the hood will find that the heart of the Z2040 is a discrete design 4-pole low pass filter with a core similar to that of the SSM2040 filter chip, used in the 80's Prophet 5 Rev 2 synthesizer, and its brother the SSM2044, used in the famous early EMU samplers and PPG synthesizers of the 80's. Both filters are considered by many to be, "the best sounding filter ever".

The Z2040's four modulation inputs are built to handle CV and audio signals, enabling deep modulation of the filter core and passing signals. A VC resonance input is provided to modulate and even clip the sine wave produced by the filter feedback loop. A Frequency Modulation input (FM) provides dynamic filter sweeps and the unique VC-FM index allows modulation of the incoming FM signals. On top of that, the Z2040 comes with an audio VCA that can be configured to act upon the input or the output of the filter.

Notes: Bucket brigade delay gets pushed into exciting creative territory with this beauty from Joranalogue. Precise analogue delay with loads of character, capable of simple chorus and flanger or more exotic Karplus-Strong synthesis and comb filtering.

Supplier's Notes:
While digital audio processors are often plagued by latency issues, analogue circuits are known for their instant response. But what if you want to delay a signal on purpose, without the use of tape or digital memory? Enter the bucket brigade delay (BBD) line: a series of capacitor 'buckets', which pass the incoming signal along at a high rate in order to delay it.

Delay 1 is a fully analogue BBD-based delay module with a multitude of features geared towards modern musical use. An integrated temperature-compensated, high-frequency voltage controlled oscillator (VCO) provides the 'clock' signal necessary to drive the delay line within 1 to 50 ms.

By increasing the drive frequency to over 20 kHz, the classic 'BBD clock whine' problem is solved, while still providing a wide range in delay time. Classic chorus, flanger and echo effects are easily achieved using the dry/wet blend, feedback and damping parameters.

To greatly reduce distortion and noise, Delay 1 includes a newly developed control circuit. The improved fidelity is maintained at a multitude of signal levels by an integrated high-performance compander, while maintaining signal dynamics.

The module's 'split phase' topology provides two different dry/wet mixes, which may be used to convert mono signals to stereo, for complementary comb filtering and more.

Delay 1 also allows you to experiment with Karplus-Strong synthesis, an exciting technique to create string and percussion type sounds. This is made easy by an integrated noise transient generator, driven by the 'pluck' input, and by the clock VCO's 1 volt per octave response.

By re-engineering the classic analogue delay line, Delay 1 brings the unique magic of BBDs into the contemporary electronic musician's arsenal.

Analogue bucket brigade delay line.
Integrated temperature-stable high-frequency BBD clock VCO with fine and coarse tuning.
Split-phase topology with additive and subtractive dry/wet blend outputs.
Blend, feedback and damping (feedback filter) parameters. Positive or negative feedback with low or high pass filtering.
High-performance BBD drive circuitry and transparent compander chain ensure optimal signal fidelity.
Dedicated pluck trigger input for Karplus-Strong synthesis.

Notes: Warp is a novel synth engine that combines the best of additive and wavetable synthesis.

In the center of Warp's control panel is a colorful XY LED matrix that represents the sound space from which Warp draws its sounds. This XY sound space consists of 32x16 frequency spectra. Each of Warp's four voices can move freely and independently across the XY space. It always uses the surrounding frequency spectra to calculate a wavetable based on 512 sine waves in real time using additive synthesis. By changing the position, wicked wavetable sounds are possible, playable with four voices and eight oscillators and navigable in two directions. An intuitive integrated editor allows playful modeling of your own frequency spectra.
With Warp's SPEC effects the frequency spectrum can be filtered and deformed in realtime before a wavetable is calculated. The wavetable can then be modified with WARP effects like wavefolder, PWM bend, overdrive and redux. The resulting wavetable serves as source for two oscillators per voice, which can be detuned and also synchronized to each other. Each voice is followed by a 12/24dB/octave high pass and low pass filter.

Warp offers an integrated editor, with which you can playfully draw and modify your own frequency spectra. The XY-Sound Space is seen as a canvas on which you can draw your own frequency peaks. Several drawing algorithms are available as tools to edit single or a group of harmonics in a musically meaningful way. There is also the possibility to derive frequency spectra from audio samples from the SD card or to put whole wavetable audio files into the XY sound space. Likewise, the XY sound space can be exported to the SD card as a wavetable audio file of any length and bit depth, so Warp can also be used as an intuitive wavetable generator for other synthesizers.

Also on board are two internal ADSR envelopes and two LFOs, which can be routed to a variety of internal destinations using a modulation matrix. To keep the overview, all modulations are color-coded and are additionally visualized by pulsating LEDs in the modulation matrix view.

Navigation through the menu is as intuitive as with our QUASAR module and is simply done via a push-encoder and a back button. The display always shows which function the four surrounding aluminum encoders currently have, and colored LEDs next to the encoders provide visual assistance. Likewise, the tuning of the module is done via a detented encoder, which adjusts the pitch either in fine steps, in semitones or in octaves. An octave switch is thus already integrated.

For all its feature-richness, Warp still remains a playable and performance-oriented instrument. The large potentiometers serve as macro controls to control several parameters under the hood at once. This keeps the instrument straight forward with a manageable number of controls, but they are all very expressive.
Likewise, the module offers the ability to save and load presets and also comes with audio files and presets on board. Thus, Warp is ideally suited for both detail-oriented sound design and hands-on performance.

In the standalone version, Warp is a monophonic four-voice synth voice that can also be used as an oscillator. With an expander module, it will also be possible to play Warp four-voice polyphonic via MIDI and CV/Gate in the future.

Warp uses a novel hybrid engine that combines the best of additive and wavetable synthesis. With the integrated editor you can playfully draw your own frequency spectra like on a canvas into the colorful XY sound palette. Warp is a feature-rich powerhouse that lets you create all kinds of sounds, from glassy clean to crunchy crunch. Thanks to expressive macro tone controls, extreme morphs are possible in a single pot turn.

Notes: Module A-101-8 is a 8-stage phase shifter which uses light-sensitive resistors (LDR) and is a replica of the Compact Phasing A manufactured by the company Schulte in the seventies. The actual phasing circuit is identical to the historic model. Only the illumination control of the LDRs is different: the A-101-8 uses LEDs to illuminate the LDRs, the historic model used incandescent miniature lamps. And the A-101-8 has no built-in LFO but can be controlled by any external control voltage source (e.g. LFO, ADSR, random, Theremin, ribbon controller, sequencer, midi). The phasing offset (i.e. the base value for the phase shifting) and the modulation depth of the external control signal can be adjusted separately. The Compact Phasing A had no offset control but only a depth control for the built-in LFO. Feedback and mixing ratio of the output signal are set by two controls. The audio input is equipped with an attenuator. The module has two audio outputs available (same as the historic model) and a visual display of the phase shifting.

The module has these controls and in/outputs available:

Control Man. : manual control of the phase shift offset (base value)

Control CV: attenuator for the signal applied to the CV socket

Control Feedb.: Feedback or Resonance (similar function as filter resonance/feedback/emphasis)

Control Mix: sets the mixing ratio between original and phase shift signal appearing at output 1

fully CCW: only the modified input signal appears at output 1 (see note below *)

center: a mixture between the modified input signal and the phase shift signal appears at output 1, that's the standard position for the classical phasing effect

fully CW: the pure phase shifted signal appears at output 1 (e.g. for vibrato effects)

Control Input Level: attenuator for signal applied to the In socket

Socket In: audio input

Socket CV: control voltage input

Socket Out 1: audio output 1 (mix signal)

Socket Out 2: audio output 2 (modified input signal)

LED: visual control of the phase shift

The module has some peculiarities (same as the historic model):

The input signal is processed at first by a pre-stage which outputs a "modified" input signal (*). This signal is not processed by the phase shift stages but is affected by the feedback setting. Only when feedback is set to zero this signal is identical to the input signal. Otherwise it contains feedback components.

This signal is output on socket Out 2.

When both output sockets Out 1 and Out 2 are used as stereo channels one obtains a spatial stereo sound effect.

The same signals is also used for the CCW position of the mix control. With mix control fully CCW the unmodified signal appears only if the feedback control is set to zero. Otherwise it contains feedback components.

The historic model had two audio inputs: one 5-pin DIN socket and a 1/4" jack socket. The DIN socket was intended for high-level line signals. When the 1/4" jack socket was used the amplification of the pre-stage increased by about 100. The 1/4" jack socket was intended for low level signals (e.g. electric guitars or microphones). For this feature the A-101-8 has an internal jumper that can be used to increase the amplification. As long as the module is used within the A-100 system usually the lower amplification is used to avoid distortion.

The 8 photo resistors and LEDs are assembled within an small lighproof box. In addition the pc boards are made of lighproof black material to avoid interfering light from other modules or the bus board.

Notes: Module A-147-4 is a dual voltage controlled LFO (Low Frequency Oscillator). Each LFO has the five waveforms triangle, sine, rising and falling sawtooth, as well as rectangle available. The rectangle output features manually adjustable pulsewidth and pulsewidth modulation by means of an external control voltage. The core waveform is triangle. The other waveforms are derived from triangle by means of waveform converters. The frequency of each LFO can be adjusted manually and modulated by means of an external control voltage with associated attenuator and polarity switch. By means of a jumper the basic frequency range of each LFO can selected: about 0.02 Hz (~ 50 seconds) ... 2.5kHz or about 0.0017 Hz(~ 600 seconds) ... 220Hz. That way each LFO can be used also as a VCO with a max. frequency of about 2.5kHz. Each LFO features a reset input which can be used to reset the triangle signal.

The module has these controls and in/outputs available:

Control F : manual control of the frequency, for each LFO the frequency range can be selected by means of a jumper from two values (see technical notes)

frequency coverage of control F in the high frequency range: about 0.075 Hz (~ 13 seconds) ... 1,4kHz

frequency coverage of control F in the low frequency range: about 0.007 Hz (~ 140 seconds) ... 125Hz

Control CV: attenuator for the signal applied to the CV socket, by means of a jumper a small positive voltage can be applied to the switching contact of the /CV/ socket, as long as no patch cable is connected to /CV/ socket the CV control then works as fine control for the frequency

Switch CV Pol.: polarity switch for the signal applied to the socket /CV/

Control PW/PM: combined control for manual and CV control of the rectangle pulsewidth:

when no patch cable is connected to socket /P/ the control is used to adjust the pulsewidth (PW) manually

when a patch cable is connected to socket /P/ the control works as attenuator for the external CV signal with a basic pulsewidth of 50:50.

Socket /CV/: frequency control voltage input, in the factory the module is adjusted so that the sensitivity of this input is exactly 1V/octave when the CV control is fully CW.

Socket /R/: reset input, according to the associated jumper the reset input is edge triggered or level controlled (see technical notes for details)

Socket /P/: pulsewidth control voltage input

Sockets with waveform symbol: output of the waveform in question (triangle, sine, rising and falling sawtooth, rectangle)

The output voltage ranges are about -5V ... +5V (10Vpp), except the rectangle output

For the rectangle output one can choose by means of a jumper if the range is about -5V ... +5V or 0...+10V.

LED: visual control of the LFO (triangle)

The inputs of the module are labelled with white characters on black background (in the text included into two slashes). The outputs are labelled with black characters.
Technical notes and special features:

The basic frequency range of each LFO can be selected by means of a jumper. The settings correspond to two different capacitor values for the VCO circuit. The relation between the two ranges is about 1:11. When the upper range is selected frequencies from about 0.02 Hz up to 2.5kHz can be generated. For the lower range the values are about 0.0017 Hz ... 220Hz. To obtain these full frequency ranges external control voltages are required. With the frequency control F only the frequencies mentioned above are possible.

Apart from that the range for the manual control F can be reduced to obtain a finer resolutuion. For this a jumper has to be removed. The range of control F is then reduced to about 1:4.5 only.

In the factory the starting voltage of the triangle output after a reset is adjusted to 0V, i.e. the triangle starts from 0V with the rising slope after a reset. By means of a trimming potentiometer the starting voltage can be adjusted to another value (e.g. to -5V).

Another jumper is used to set the reset behaviour to edge triggered or level controlled. When set to edge triggered the rising edge of reset signal is used for the reset (independent of the duration of the "high" state of the reset signal). When set to level controlled the triangle output remains at the starting voltage as long as the reset signal is "high". Only when the reset signal turns "low" the triangle starts.

Notes: Part of Xaoc's Leibniz binary system, the Rostock is a digital delay line capable of processing triggers, audio, CV and video signals. Another useful module from the unique Leibniz series.

Supplier's Notes:
Rostock is a component of the Leibniz Binary Subsystem. It is a data pipeline, a FIFO (first in - first out) shift register, or a very short digital delay. The module operates similarly to a BBD delay or an ASR (analogue shift register), except that it is digital. It consists of a chain of memory cells that pass bits from one to another at each clock cycle. The delay length is variable from 1 to 64 stages (with optional looping and scrambling). It works by processing data in the Leibniz bus and must be connected to other Leibniz modules using data ribbon cables at the back. Rostock may process data sequences representing rhythms, control voltages, audio-rate signals, and even video signals because the bits can change at extreme rates (up to 2MHz). In addition, its memory may be digitally looped. Delaying and looping is a fundamental building block for sequence automation, pattern and chaos generation, and various cybernetic modular patches. Thus, Rostock is a multi-purpose open-ended device that invites creative thinking.

Notes: Roucha Legio is a 12 dB /octave state-variable stereo multimode filter available on the Legio DSP+oscillator platform.

Noise Engineering received tons of requests for NE filters over the years, and Roucha Legio is their first dedicated release. The filter features lowpass, bandpass, and highpass settings and tracks frequency via the dedicated encoder and extremely accurate 1v/8va CV input. Roucha Legio's CV-controlled resonance parameter can go from clean to acidy-squelchy for bassline joy. Add CV for filter sweeps that will knock your socks off. Of course, because it's a Noise Engineering module, there's a Fold knob. Add wavefolding to the signal chain before, after, or both before and after the filter.

Noise Engineering have made it easy to carry out dramatic buildups and cuts with Roucha Legio. Just tap the encoder to bypass; tap again to turn the filter on again. Want to automate it? Send a gate into the Bypass input. The filter will remain bypassed as long as a high gate is present.

Roucha Legio is also a DSP and oscillator platform: users can change the firmware on any Legio module, 100% free, to any other firmware in the Legio series.

Notes: AXON-2 is an 8HP expander module for the SQUID SALMPLE, MFX and Pamela's PRO Workout that like the AXON-1 provides 4 additional freely assignable CV inputs but additionally adds manual offset controls and 2 additional 'performance' buttons.

The addition of AXON-2 increases the Squid, MFX or Pam PRO's total number of CV inputs by 4, greatly increasing the possibilities for vast modular manipulation. Each of the CV inputs includes an offset for hands on control over parameters assigned to CV. Per assignment digital attenuation and offset via the host module is also available for fine tuning the modulation or control over parameters.

The AXON-2's large buttons are great for controlling select functions in a live performance environment or adding convenient quick navigation shortcuts when making edits. The buttons functionality and assignability are dependent on the host module. See respective manuals for details.

NOTE: AXON-2 support requires the latest firmware be installed for Pam Pro (120 or newer), Squid (187 or newer) and MFX (105 or newer).

Notes: Voltage control is the basic tenant of modular synthesis: parameters may be modulated by changing control voltages (CVs), simply by plugging in a patch cable. However, during patching it's common to encounter incompatible voltage ranges, with signal outputs and inputs having different amplitudes and sensitivities.

An indispensable utility module, Bias 2 provides a compact yet precise solution to quickly interface signals between modules within a Eurorack modular system, without interrupting your creativity.

Comprising of two independent sections, each with dual inputs and dual outputs, its carefully selected combination of normalised reference voltages and amplification/attenuation factors makes it a breeze to convert between the most common signal ranges: -5 to +5 V, 0 to +5 V and 0 to +10 V.

Precision comes standard on Bias 2, with meticulously engineered analogue signal paths providing absolutely transparent performance for any Eurorack signal: CV, audio or gates/triggers.

Beyond the voltage conversion application, Bias 2 is a true all-rounder, capable of functioning as a pair of dual input unity gain mixers, -6 and +6 dB audio gain stages or a multi-output fixed voltage source.

Notes: Designed specifically for dance music, the Mandrake is Malstrom's solution to all your kick drum needs. Versatile, expressive and punchy as hell, this analogue module delivers pure dance floor power.

Supplier's Notes:
A kick drum lays down the foundation of your track, the root of your beat. You need the low end to create a pumping motion and the high end to cut through the mix. All this while maintaining spectral room for other sounds. So it can be quite an undertaking to get right.

Which is why Malstrom have developed Mandrake. A kick drum synthesizer that targets kick drum sounds for Dance, House and Techno music. Inspired by physical models, DAW drum synthesis and sound mixing techniques. It divides the sound into a "Hit" and "Body", with sound shaping possibilities for both sections.

Mandrake's "Hit" is a resonating filter which is saturated to have a square-like shape. It generates a short pulse that can be tuned and attenuated. Which results in a short click that will cut through the mix when and where you need it.

Mandrake's "Body" is made up from another resonating filter. Its wave is slightly saturated and filtered to resemble the harmonics of a drum. More saturation can be added in the form of uneven harmonics to create harsher tones. The result is then sent to a damping circuit that is used to tame the sound. Finally the body can resonate which leads to more liquid sounding drums, or specific frequency boosts. All of the body's parameters are connected which makes it super fun and playable!

A few more functions allow Mandrake to be adaptable to different situations. Two shapes with different harmonic content and volume decay shape. An envelope output to provide a normal or ducking envelope to further sculpt your sound, or to side chain other sounds. An accent or volume CV input to provide two volume control options. And a clean-up switch which adds a high-pass at 25Hz to remove the rumble, a spectral dip at 300Hz to make the kick sound less "boxy".

Mandrake is not another 808 or 909 clone; its analogue circuitry is entirely built from scratch to create an original sound. Also nothing more than a great kick; ranges to get into detail, and useful kick drum sounds throughout its settings!

Features

- "Hit" and "Body" sections to sculpt the most important parts of a kick drum.
- Hit-timbre and Hit-volume controls to shape sound of the transient.
- Body saturation, resonance, decay and damping controls provide a varied sound palette.
- Clear pitch control section that is carefully scaled to match a kick drum.
- Two VCA shapes that provide different flavours.
- Ducking or normal Envelope output to further sculpt and modulate.

Notes: The successor to Eowave's Fluctuations Magnetiques module is an even more advanced quad analogue filter, designed for cross modulation, complex routing and self-oscillating fun.

Supplier's Notes:
The Tempete Magnetique is a fully analogue complex filter/synthesizer module.

It was that was created as an evolution of the "Fluctuations magnetiques".

More than a mk2, Eowave designed it to push you to play with one of the most interesting things in modular synthesis: to divert the primary usage of a module to create unexpected and new sounds (aka this is not only 4 filters)

Tempete Magnetique is deeply inspired by the classical filters design as well as West Coast synthesis complex oscillators.

At it's core, has 4 multi-mode 12db filters that can be chosen to be routed in series or parallel, which can be used independently or combined and even cross-modulated, controlled by CV or with an integrated envelope follower (which can be used as a dynamic responsive envelope) and even pinged.

The Tempete Magnetique was designed to have several levels of use. The individual level with the use of separate filters, perfect for quadraphonic processing of different sources (A B C D).

The pair sections which allows for more complex stereo effects or to generate synthesis voices (X, Y) and finally, the global level with a cross-modulation of filters.

The independent outputs have been designed to be fed back into their input, turning them into oscillators (not really precise one, but you can make synth voice kind of V/Oct tuned with their very own sound, due to the fully analogical design, these oscillators may have strange behaviours sometimes, but this instability will bring you the warmth of analogue gears).

The pairs sections, of course, can filter an incoming signal, but can be transformed to full synthesis voice, percussion engine (exited by the ping input and modulated with the envelope follower) and way more.

This filter allows for anything from gentle, subtle filtering to a storm where the undulations of your sound and their intensity create new types of textures.

Main features:

Four independents or linkable multi-modes 12 db filter
Envelope follower who can act as end decay envelope sensible to the velocity
Cross modulation engine who modulate both pair of filters
Ping input
Outputs with phase correction to be fed to inputs

Some applications:

Filtering (obviously), can be used for quadraphonic or stereo filtering
Weird synth voice

Notes: An ART wavetable dual oscillator mono voice source that can be used to build polyphonic patches and multi voice patches. It generates its harmonically rich sound using two 80s vintage D/A converters to feed your filters and effect processors. VORTEX comes loaded with dozens of wavetables, plus additional user wavetables can be loaded from the front panel SD card. A detune knob controls the second VCO and adds effects from deep phasing to a sub octave. The position knob and CV input selects waves in the tables and vibrato from LFOs to create FM. Like other ART sound generators a dedicated Gate output manages the voice envelope or any modulation synced to that voice. VORTEX is a great companion to the analog ATX1 and a must for digital synthesist enthusiasts.

Size: 8HP - Depth: 40mm / 1.5"
Power: +12V 80mA / -12V 25mA

Notes: A classic all analogue saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analog polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. TipTop consider the ATX1 the best sounding analogue VCO they have ever created.

Power: +12V 105mA / -12V 33mA

Notes: OCTOPUS is a powerhouse ART controller that takes MIDI in via the USB or DIN connector and outputs 8 ART channels with 8 velocity CV plus 8 drum triggers. Together with the ART oscillators the OCTOPUS provide unprecedented simplicity connecting the modular to your computer sequencers, hardware midi sequencers and keyboards. Each ART channel can play polyphonic notes, monophonic notes or create multi-channel polyphony using an internal voice manager. All together OCTOPUS can play more voices and notes from a single controller than ever was possible in modular. Using ART high speed control signals OCTOPUS can maintain low jitter for tight timing.

Please note, OCTOPUS is not a 1V/Oct midi to CV and should not be confused as one.

Take a DJ-mixer-style combined high-pass and low-pass filter, cram it into Eurorack and you have the DJ VCF. A simple formula, but one perfected by Erica's attention to detail, with CV control and adjustable resonance.

Supplier's Notes:
As its name suggests, the Erica Synths Black DJ VCF provides sound treatment functionality typically found on DJ decks - it is fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is applied. The filter also has a nice-sounding resonance parameter. This module provides hands-on control over the sound during the performance, as well as unconventional timbre modulations that are hard to achieve with conventional state variable filters. The Black DJ VCF is a fully analogue design and consists of two VCFs - highpass and lowpass in series and the filter management is done by complex CV routing.

CUTOFF
This is the main control of the module - manual cutoff frequency adjustment with a twist - it's fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated

AUDIO LVL
Adjust the audio signal level

RESONANCE
Adjust the resonance level manually. On settings over 1PM, the filter will start to self-oscillate. The resonance is incoming audio signal-sensitive - a signal of greater amplitude may reduce the impact of resonance on the resulting sound

CV1 LVL
This is the cuto CV attenuverter. Adjust the CV level to your taste! Notice that the cutoff CV works differently compared to conventional state variable filters - it sweeps the filter from closed lowpass through fully open to closed highpass

CV2 LVL
This is another cuto CV attenuator

CV2 IN
This is the cuto CV2 input, which is controlled by the attenuator knob
