Synth modules

Notes: The Quad VCA is a compact and feature packed module that is sure to find its way it almost all of your patches. In addition to being used for standard VCA duties it can also be used as a mixer and signal booster.

Features:

- Manual LEVEL control per VCA which is convenient when using the module as a mixer or for biasing when CV modulating the VCA with a bipolar LFO.
- Dedicated CV attenuators with dual colour LEDs for monitoring bipolar CV signals.
- Continuously adjustable response from linear to exponential per VCA.
- Each CV input is normalled to the adjacent one for cascaded control.
- Each output is normalled to the mix input of the adjacent one which allows you to use adjacent sets as submixes or the fourth output can be used as a master mix output when none of the other outputs are patched.
- Each VCA has a boost switch that increases the output level by approximately +6dB (double).

Notes: The shorter and wider brother to the popular Triatt module!

The four handy knobs can act as active attenuators (unipolar) or attenuverters (bipolar) depending on the setting of the two-position switches above each one.

Each input is normalled to a precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 v or -5 to +5 v depending on the position of the mode switch.

- 2 modes for each channel
- 5v normalled to each input
- With external signals it acts as active/buffered attenuator/attenuverter/mixer
- Each output normalled to mix into the adjacent channel on the right making it possible to do sub mixes in groups of 2, 3 or all four channels.

Notes: Best value Buchla module ever? An official Buchla module produced by TipTop Audio, the 258t is a dual triangle-core oscillator, with sine/sawtooth wave shapes in the top half and sine/square at the bottom. Bags of character.

Supplier's Notes:
Two independent voltage-controlled oscillators. Each has one processing input, a frequency modulation input and a 1V/oct input.

Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

Trimmers:

There are three trimmers for each oscillator on the back of the module:

1V/oct is the octave tracking trimmer and is set at the factory using high precision instruments.
SHAPE is the trimmer that set the sine wave, for the lower harmonic content of the sine wave.
VC WAVE SHAPE sets the response of the waveshaper to the incoming control voltage. Both SHAPE and VC WAVE SHAPE trimmers are used to adjust the sine wave purity.

Notes: Mixup is a versatile, expandable audio mixer for Eurorack format. It has eight inputs (6 on the front panel) and two outputs. Inputs 1 and 2 are single-channel mono inputs, each with its own mute switch and level control; Input 3 is a dual-channel stereo input with a shared mute and level control; and input 4 is an auxiliary unity-gain, non-mutable stereo input.

Using bus connectors on the back panel, you can chain multiple Mixups together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing around larger systems.

Because Mixup is designed specifically for audio (and not for CV mixing), it uses AC-coupled circuitry (which reduces the potential for 'pops' when muting and unmuting audio), and it uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.

Notes: 'Tangle Quartet' is a high quality quad linear voltage controlled amplifier (VCA) providing individual level control of 4 signal inputs with both individual outputs and a combined 'mix' output (for non patched outputs) . Control signal inputs and associated attenuation controls allow for voltage control of signal levels. Control inputs are normalised to 5v thus providing manual mix control in the absence of control signals.

Notes: Module A-138n is a simple four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator available. The output is twice available (two sockets, hard-wired like a multiple).

The module is the slim version of module A-138a and offers nearly the same features. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is half the width of the A-138a. The module is primarily planned for applications where only limited space is available. The only functional difference compared to the A-138a is the missing attenuator for the (dual) output.

Width: 4HP / 20.0 mm
Depth: 30 mm (measured from the rear side of the front panel)
Current: +10mA (+12V) / -10mA (-12V)

Notes: Seriously potent polyphonic voice built around 16 sine-based oscillators. Capable of a huge range of tones thanks to FM, phase distortion and wavefolding. Another cracker from a consistently reliable brand.

Supplier's notes:
The Ensemble Oscillator is a unified polyphonic voice of sixteen complex oscillators combining additive, FM, phase-distortion and wavefolding synthesis techniques in new unorthodox ways. By quantizing the oscillators to scales or series of harmonics, the Ensemble Oscillator allows you to explore the sonic boundary between musical chords and rich evolving textures. Easily create a wide variety of sounds ranging from aggregates of pure sine waves to pulsar synthesis or pristine harmonic tones and lush wide chords to rich dirty drones and rumbling glitches. Custom scales can quickly be "learned" and saved using a CV keyboard or by manually entering notes with the controls.

The Ensemble Oscillator is designed by Matthias Puech and 4ms Company.

30 factory-programmed, user-writeable scales organized in three groups:
12TET: all notes quantized to equal temperament, repeating over octaves
Octave: unquantized notes, repeating over octaves

Notes: Belgrad is an all-analogue voltage controlled filter module which - on par with our other modules - brings something new to the table. While it can be used as a traditional VCF for "academic" subtractive synthesis, we guarantee countless hours of exciting timbral explorations thanks to its unique character, flexibility, and features. The most prominent feature is that it offers a multitude of frequency responses with two resonant peaks.

- Eurorack synth compatible
- 14HP, skiff friendly
- Current draw: +45mA / -42mA
- Reverse power protection

Notes: A-138s is a simple but useful 4-in-2 mixing tool. It has four inputs available. Each input is equipped with an attenuator (Level) and a panning control that is used to distribute the signal to the left and right output. Beyond stereo mixing it is equally suited to create variable parallel routings. For example: Any of the four inputs may be routed in variable intensity to feed two filters.

You may regard the A-138s as a smaller version of the A-138m Matrix Mixer.

Inputs and outputs are DC coupled, i.e. the module can be used for the mixing of control signals too.

- 3U Eurorack module, 8 HP wide, 30 mm in depth
- Power consumption: 10 mA at +12 V and 10 mA at -12 V

Notes: A-135-2 is a miniature version of the A-135-1. Behind a front panel with 8 HP only four linear VCAs (voltage controlled amplifiers) and a voltage controlled mixer based on the VCAs are available.

Controls, In/Outputs and Functions of each VCA:

- Level (manual control of the VCA amplification), small rubberized knob (L1...L4)
- Control voltage input with associated attenuator (CV1...CV4), for the full VCA control range about 0...+5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker
- Signal Input
- Signal Output
- All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. to control the level of LFOs or envelopes)
- The signal input is not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5...+7.5V without clipping. In case of higher levels an external attenuator is required (e.g. A-183-1).
- The available amplification range is 0...1, the maximal amplification is 1 (i.e. it "clips" and remains at 1 even if the control voltage goes beyond the value that corresponds to amplification 1)

Functions of the voltage controlled mixers:

- Two outputs ("Selected" and "All")
- Selected output: the ouput if a VCA is removed from this sum signal when a plug is inserted into the corresponding VCA output.
- All output: sum of all VCA outputs, regardless of inserted plugs into the VCA outputs
- The maximal amplification is about 0.6 to avoid clipping at the mixer outputs (otherwise the outputs may distort with 15Vpp signals at each signal input and full amplifications)

Special functions of the voltage controlled mixers (selectable by internal jumpers):

- Dual Stereo VCA: In this case the control unit of VCA1 (L1 + CV1) affects also VCA3 and the control unit of VCA2 (L2 + CV2) affects also VCA4, the control units of VCA2 and VCA4 are out of operation
- Quad VCA: In this case the control unit of VCA1 (L1 + CV1) affects all four VCAs. The control units of VCA2, VCA3 and VCA4 are out of operation. In this mode the module has the same function as module A-132-2. That's why module A-132-2 will be discontinued.
- Normalling of the signal inputs: by means of internal jumpers signal input 1 can be normalled to signal input 2, signal input 2 to signal input 3 and signal input 3 to signal input In 4. That way the same input signal can be distributed to four different channels by means of control voltages (e.g. quadrophonic distribution of audio signals). Suitable control voltage sources are e.g. A-144 (Morphing Controller) or A-143-9 (Quadrature LFO).

Notes: Module A-138m is a 4 x 4 matrix mixer with switches for unipolar/bipolar mode for each column. Unipolar means that the controls work as attenuators. Bipolar means that the controls work as polarizers. In this mode the amplification is zero in the middle position of the corresponding control. Turning the knob counterclockwise from the center position the signal is subtracted from the output sum with increasing amount (i.e. negative). Turning the knob clockwise from the center position the signal is added to the output sum with increasing amount. The module is DC-coupled and can be used for both audio and control voltage mixing.

By means of an internal jumper one can select if the four upper controls work as DC offset generators - provided that no patch cord is plugged into the upper input socket. If this feature is not required it can be deactivated by removing the jumper on top left of the pc board. The function is identical to the A-138a/b.

Notes: Module A-130-8 contains eight linear voltage controlled amplifiers (VCAs). Each VCA features a control voltage input (CV), a signal input (In) and a signal output (Out). In addition three mixers are included: the socket labelled "1-4" outputs the sum of the VCAs 1-4, the socket labelled "5-8" outputs the sum of the VCAs 5-8, the socket labelled "1-8" outputs the sum of all eight VCAs.

The signal inputs are able to process levels up to about 20Vpp without clipping (20Vpp = 20V peak-to-peak or about -10V...+10V) . Each CV input is equipped with a trimming potentiometer that is used to adjust the sensitivity of the CV input in question. In the factory the module is adjusted for the CV range 0...+5V but can be re-adjusted by the user for other control voltage ranges (e.g. 0...+10V).

The amplification range for each single VCA is 0...1. The signals of the sum outputs have a lower amplification to avoid distortion at the sum outputs.

The VCAs and mixers are fully DC coupled, i.e. the module can be used for the processing of both audio and control voltage signals. The control voltage and signal inputs can be normalled by means of small solder pads (e.g. 1 > 2 > 3 > 4 and so on, or 1 > 5, 2 > 6, 3 > 7, 4 > 8 for the stereo application mentioned below).

Typical applications

any kind of VCA application (e.g. voltage controlled attenuation of audio or control voltage signals)
two voltage controlled mixers with four channels each
voltage controlled stereo mixer with four channels each, for this the control voltage inputs have to be correspondingly patched or internally normalled: CV1=CV5 /CV 2=CV6 / CV3=CV7 / CV4=CV8
voltage controlled mixer with eight channels
add-on for the Joystick module A-174-4
Technical notes

The following document shows the positions and functions of the jumpers and trimming potentiometers of the module: A130_8_trimming_potentiometers_and_jumpers.pdf
When the trimming potentiometer in question is moved CCW (counterclockwise) the sensitivity of the CV input in question increases (view to the top edge of the module).
Trimming procedure: apply the max. CV voltage that will occur in your application (e.g. +8V) to the CV input and a constant audio signal to the audio input (e.g. a VCO sawtooth). Then adjust the trimming potentiometer in question until the max. output level is reached and does not become higher even if the trimming potentiometer is turned further. Possible the the trimming potentiometer has to be turned back again a bit to find the correct position.
With the trimming potentiometer adjusted to max. sensitivity the linear amplification starts at about +0.1 control voltage (CV). We introduced this small dead range of about 100 mV to make sure that the VCA fully closes with CV = 0V.
It's possible to change the amplifications of the internal mixers used for the sum outputs (1-4, 1-8, 5-8) also to 1. Pay attention that then clipping/distortion may occur at the sum outputs. For this the 22k resistors R41 (Sum 1-4), R44 (Sum 5-8) und R51 (Sum 1-8) have to be replaced by 47k. As they are smd resistors sufficient experience with soldering/desoldering of smd parts is essential. And we have to point out that warranty is void if such modifications are carried out by the customer. The positions of the resistors are shown in the document A130_8_trimming_potentiometers_and_jumpers.pdf.
If multiple exponential VCAs are required module A-132-4 is recommended.

Notes: The Intellijel/Cylonix RAINMAKER eurorack-format module provides a high-quality (96KHz sampling rate with 32-bit internal processing) stereo rhythmic delay and stereo comb resonator effect.

The stereo rhythm delay has 16 taps, each with its own resonant 2nd-order filter and granular pitch shifter. The filters have independently adjustable resonance and cutoff frequency, and can be set to either lowpass, bandpass, highpass or bypass operation. The filters are also capable of self-oscillation, enabling modal synthesis techniques. The granular pitch shifters have a range of 15 semitones up or 16 semitones down. Each tap can repeat at a rate value set in tap#'s in order to create regenerating echo effects. The feedback signal has a lowpass/highpass tone control and its own pitch shifter. The tap delay times can range from 0.1 millisecond up to a maximum of 20 seconds. The overall delay times can be set with the rotary encoder, the tap tempo button, or synced to an external clock.

The stereo comb resonator section has 64 time-delayed taps which are summed together. This produces a deep comb filter or resonating effect. At large comb sizes (long time delays) a multiple echo effect is produced. The density of the resonator can be varied from 2 to 64 taps. The tap with the longest delay time is fed back to the input. High feedback levels, with short comb sizes, produce "Karplus-Strong" types of plucked string sounds. The relative timing of the 64 taps are set according to one of 16 different preset patterns, which provide different resonator timbres or echo rhythms. The comb size can be set either with the rotary encoder, an external clock or through a transposable 1v/oct input voltage.

The Rainmaker module has extensive voltage control capabilities. Direct voltage control is available for the delay feedback level and tone, the global pitch shift for all delay taps, the comb resonator size, and comb feedback level. There are two assignable modulation inputs, which can be assigned to different parameters in each preset. A trigger input with assignable functionality can trigger built-in types of noise bursts, freeze the delay buffer, reverse the delay, randomize parameters, mute taps, and much more.

Notes: The Spherical Wavetable Navigator (SWN) is a six-channel synthesiser that makes it easy to create slowly morphing drones, polyphonic melodies, evolving sequences, and rich textures.

The SWN features six wavetable oscillators with independent pitch, level, and waveform controls. Six LFOs (Low Frequency Oscillators) can be used as modulation sources and/or envelopes, making it easy to add dynamic motion to your patch. Each channel is a full voice and can be "played" using the top row of buttons, the internal LFOs, or note-change detection on the 1V/oct jacks. The SWN ships with 12 three-dimensional (spherical) wavetables and an easy interface which allows you to record and edit custom wavetables from live audio. Open-source software for Mac, Windows, and Linux called SphereEdit can be freely downloaded and allows you computer to create, edit, and convert .wav files into Spherical wavetables to transfer into the SWN with an audio cable.

New firmware available which adds extra features, visit https://4mscompany.com/p.php?p=820&c=5 for details.

Notes: Third-party clone of the open-source Mutable Instruments Plaits oscillator/sound source. All the same functionality in a compact 8hp format with full-size knobs for the key functions.

Supplier's Notes:
Functionally identical clone of the Mutable Instruments Plaits. Beehive strikes a nice balance between size, reducing 12hp down to 8hp, and playability by offering full size knobs for the four main functions. Beehive also retains the same depth of the original module at 25mm. This module uses After Later's new aluminum knobs which have a nice non-slip texture and allow for more finger space over the standard 1900H Davies knobs.

Notes: The 333 is a summing and distribution module for Eurorack modular systems.

It is composed of three identical sections, the red, yellow and green, each of those featuring three inputs summing amplifier with three independently buffered outputs.

Derived directly from the CGM creative mixer series, the sum section is DC coupled, allowing the sum of control voltages as well as audio signals.

With an extremely low tolerance in both sum and output sections, it is suitable also for summing quantized voltages like the ones coming out from the quantized outputs of the SAPEL.

In case CVs or audio signals are particularly hot, the 6dB attenuator might be helpful to reduce exactly by 50% the incoming signals.

Red and yellow output are also normalled to the 1st jack socket of the yellow and green input: in this way this module can also work as a 1 to 9 buffered multiple.

Notes: Triplatt is a three-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch.

Each input is normalled to a built-in precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch. Outputs A and B are also capable of a range of 0-10 / -10 to +10 when using the special function switches.

Each output is normalled to mix into the output of the channel below, making it possible to do sub mixes in groups of two or three.

In addition, each channel has a "special function" switch to alter its input voltage in a specific way. Channel A has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A. Channel B has a +5V switch, allowing you to add 5V to whatever voltage is sent into Channel B. Channel C has a mute switch, allowing you to completely turn off the signal being sent into Channel C.

Notes: Any signal can be expressed in terms of a few parameters: frequency, phase, amplitude and timbre. It is through modulation of these aspects that synthesists create electronic sound. With Generate 3, it is now possible to create a signal and control all its parameters by through-zero modulation within a single 12 HP wide module.

Everything starts with the exceptionally precise triangle-core voltage controlled oscillator (VCO) at the module’s heart. Through-zero linear frequency modulation (FM) enables rich yet pitch-stable FM sounds, by allowing the oscillator to run backwards into ‘negative frequencies’.

The resultant triangle wave is then processed by the through-zero phase modulator, providing a total phase shift range of 900°. Phase modulation offers an interesting alternative for FM, as it enables deep FM-type tones without actually changing the oscillation frequency.

The timbre of a signal is determined by its harmonic content. This full set of harmonics can be grouped into three main parts: the fundamental, even and odd harmonics. Generate 3’s harmonics generator separates out these three timbral ‘channels’. By adjusting their relative amplitudes, a vast array of different waveforms can be created, including but not limited to the classic sine, saw and square waves.

While the amplitudes can be adjusted manually, each timbral channel supports through-zero amplitude modulation, also known as balanced or ring modulation. When audio-frequency modulation signals are applied, the harmonics become ‘split’, enriching the spectrum.

In addition to all the usual analogue synthesis techniques, the extensive set of modulation options makes Generate 3 especially suited for exploring multiphonic synthesis: a monophonic source creating a complex timbre, much like throat singing, yet by electronic means.

Notes: From trickling hi-hats to thunderous kicks. The Befaco Percall 4-Channel VCA/Delay Envelope Module is designed to take care of all percussive aspects of your Eurorack rig. You'll be able to create a whole host of percussion thanks to the 4 VCAs, volume control and decay options. By using the trigger you'll be free to open the VCA whilst the volume knob helps determine the level of the percussive sound you've sculpted. Take your tones to the next level thanks to the inclusion of an output on the envelope. You can apply this to the pitch of the oscillator to achieve a fat kick drum which offers excellent low frequency energy. The Percall 4-channel module is the ultimate addition to your Eurorack.

Notes: Chimera is a granular synthesis module that specializes in drum sounds. It offers a wide range of detailed sample sources as well as its own synthesis engine. Firmware updates can be performed via USB.

The module features various samples called Surfaces. The samples are mainly metallic sounds:

Tambourine
Bells
Drill
Wrenches
Cartridge cases
Coins
Chains
Metal housings
Broken modular front panels

Chimera uses impulsive sounds with lots of detail and long decay times to create detailed shaker-like sounds. The granular synthesizer was developed around the samples here, this has the advantage that the percussion sounds sound so more natural.

Power consumption: 63mA at +12V and 17mA at -12V

Notes: Originally inspired by audience applause, hip-hop samples, and classic drum machines, Fracture is a multi-particle percussion synthesizer that applies concepts from classic analogue clap circuits to granular synthesis methods.

It all starts from proprietary micro-samples we recorded specifically for this purpose and ends with an engine built to suit these samples.
Unlike our other percussion module, Chimera, which uses impulse rich samples as it's tonal center, Fracture uses single impulse samples like claps, snaps, ping pong balls, opening a beer can, and many more. It then plays a group of similar samples back in a psuedo random order for unique hits. Density, Decay, and Tail affect tone and how "tight" your virtual clappers are to playing together.

Our goal was to design a clap percussion module covering the range from classic drum machine claps all the way to full audience applause. We ended up with a module that covers a huge range of timbres beyond claps. We hope this engine provides you with the tools to intuitively create wild percussion sounds that bring your system to life in a new way.

Notes: Black Stereo Mixer is just what you need, if your setup has several nowadays gaining popularity modules with stereo inputs or outputs, like Black Hole DSP, Erica Fusion Delay, MI Clouds or some other. In order to save rack space, we designed compact mixer with lot of cool, performance oriented features.

In order to save rack space, we designed a compact mixer with a lot of cool, performance oriented features.

Check out also the Black Pre-fade Listen Expander that is a satellite module to Erica Synths Black Stereo Mixer!

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

Notes: After Later's redesigned take on the classic Mutable Instruments Rings module offers all the distinctive resonant synth sounds you'd expect, from strings to percussion. Great value.

Supplier notes:
This is an exact hardware replica of the Mutable Instruments Rings module.

Notes: The Stereo Mixer 1U provides a convenient way to combine your mono and stereo sources into a single stereo mix. There is level control over the first two channels and, using a rear connector, you can chain multiple Stereo Mixer 1U's together into a hidden 3rd stereo channel without using up channels on the front panel. The chain i/o connectors are fully compatible with the Mixup connectors so you are able to mix 1U and 3U mix chains together as needed.

The Stereo Mixer 1U is a versatile, expandable audio mixer for the Intellijel 1U format. It has two pairs of front panel inputs, each with its own level control, and a mixed output pair. For each input pair, the left channel is normalled to the right channel, for mono operation.

Using 3-pin Link connectors on the back panel, you can chain multiple Stereo Mix 1U's together in series, giving you the ability to mix together even more inputs, or to create sub-mixes for routing audio around larger systems. You can also these same connectors to patch Intellijel's Mixup and XY IO 1U modules to these back-panel chains, and you can connect them directly to the 14" audio jacks on an Intellijel Palette Case, a 7U case with 2nd-generation Audio Jacks Board, an Outs module, or a v2 Headphones 1U.

Stereo Mix 1U is designed specifically for audio (and not for CV mixing), it's AC-coupled, and uses audio-grade, logarithmic attenuators for a smooth, even response across the entire volume range.

Notes: The Jumble Henge is a 16 input stereo spectral mixer with a unique patch-based mixing interface in a compact space. Each input has a carefully tuned resonant analog filter and a unique fixed pan value, providing each sound its own space within the mix. There is a Mix control to adjust the depth of the filtering and a clean external stereo input for chaining with another mixer or extra sound source. Jumble Henge is a space efficient solution for creating rich stereo mixes from a number of both mono and stereo sources.

INPUTS
Vertical and horizontal patch position determines a source's spectral and stereo placement in the mix respectively.

Aside from centred inputs, every input sits in its own unique pan position, helping to keep a separation between sounds but building a complete stereo image when combined.

The centre right inputs of the top two rows are normalised to the centre left inputs. - i.e if just a left input is patched it will be effectively panned center.

Towards the highs the panning becomes wider - as the human ear better pinpoints direction at higher frequencies, whereas the lows remain more centred for a tighter, more focused sound.

MIX CONTROL
Mix control for the overall depth of the filters applied to the inputs. Note: a slight volume increase occurs near the centre of the dial.

EXTERNAL INPUT
An additional clean stereo input pair for chaining with another mixer or additional source. Right input normalised to left input to accomodate mono sources.

OUTPUTS
Stereo mix output, the sum of all 16 inputs.

Jumble Henge was designed in collaboration with Worng Electronics and is based on the 'SoundStage'.

Notes: The legendary Buchla 259 complex oscillator gets the officially licensed Eurorack treatment from TipTop Audio. One of the most versatile and characterful VCOs ever made, with endless cross-modulation options and wave shaping features. Iconic.

Supplier's Notes:
The 259t is the largest and most complex analogue oscillator from Don Buchla's legendary 200 modular synthesiser. The 259 originated the concept of the "Complex Oscillator" in the 1970s and has been reissued by Buchla and Tiptop Audio in Eurorack format. The module consists of two oscillators, called the Modulator and Principal, with a middle section that provides voltage control over the internal modulation paths between the two oscillators, resulting in highly complex timbres. Additionally, the principal oscillator passes through multiple unique voltage-controlled waveshapers and crossfaders for further signal processing. The module's pitch can be controlled with 1V/OCT or via its internal auto-tuner and ART control to create precisely pitched notes.

Notes: A unique graphical take on an oscillator design, E-RM's brand-new polygonal synthesis approach is unlike anything else we've seen. Stereo oscillator capable of a huge range of timbres. Innovative stuff.

Supplier's notes:
The polygonal synthesis is a kind of graphical complex amplitude shaping method. With the help of the built-in modulation sources, polygonal synthesis in polygogo opens up a wide range of sonic possibilities from clicky pinged sequences to unique dark thunderstorms, bass lines, leads and colored noise.

This mighty stereo oscillator impressed the audience with its wide range of possible timbres. The idea of sculpting a shape on the screen of the module that then translates into sound works really well and invites the user to interact with the module.

Notes: Module A-138 is a four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator, and there's a master attenuator, so that the mixer can be used at the end of the audio chain, i.e. it can be used to interface directly with an external mixer, amplifier, etc.

The A-138b has potentiometers with logarithmic response, so is especially suitable for audio signal mixing.

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 XPO or Stereo Prismatic Oscillator music synthesizer module is a Voltage Controlled Analog Oscillator designed for generating Sine waves, Triangle waves, Sawtooth and Spike waves, Sub-Octaves, Stereo Timbre Modulations (including Pulse Width Modulation and Wavefolding), Oscillator SYNC, Linear FM and more in the analog domain.

The XPO is designed to be the Stereo VCO complement to our Stereo Filter, the QPAS. The two modules share the core idea of complex circuits being controlled in multiple dimensions in the stereo field by a few powerful parameters. The Stereo Prismatic »

Notes: Dual 3:1 audio and cv mixer (up to three buffered inputs with a single buffered output).

NOTE: Version 2 of the Unity Mixer has two sets of jumpers on the main pcb. These allow the top and bottom sum to be set to -6dB attenuation instead of unity gain. This creates more headroom when summing higher amplitude sources like raw VCO signals.

Notes: To any new modular system owner, the need to easily combine different voltage sources quickly becomes apparent. While a mixer is the obvious solution, these modules are not suitable for adding precise pitch control voltages (CVs) since the channel gains cannot be set exactly to unity.

Add 2 provides a compact solution to this problem, precisely summing the input signals down to 1 or 2 outputs. Alternatively, each section can be configured as an averager using the jumpers on the rear. This way, LFO waveforms or audio sources can be combined while maintaining the average signal level and avoiding clipping. The high-end components provide exceptional performance, making Add 2 suitable for audio, control voltages and gates/triggers.

With the bottom section's first input not in use, the top output is injected into the bottom. This allows 5 signals to be combined into 2 outputs, adding flexibility to your patching.

Compact and skiff-friendly module

The driving idea behind the Twin waves voltage-controlled dual oscillator/LFO is to offer two interesting oscillators in a skiff-friendly and compact size. To achieve that challenge, Klavis built the product's architecture on the concept of pre-defined algorithms, where the most useful configurations and their matching parameter are ready to use.

This MKII evolution brings a redesigned layout, additional knobs for more hands-on fun and semi-modular cross-patching between sections.

All of the original features are present: a top selection of synthesis techniques, each with their key parameter directly at hand, enriched by a full set of complementary features.

More than ever, the Twin Waves is versatility at its best.

Notes: The 'MEGA-TANG' is a 4-channel linear VCA and stereo mixer providing per input control over level, effect send, pan and muting. Designed for live use in mind with a simple & compact layout, the 'MEGA-TANG' builds on the clean and transparent sounding Tangle Quartet VCA by adding a stereo mix output, effect sends (mono send with a stereo return) which pair great with the MFX, manual panning, soft mute buttons with LED indicators and an expansion port for future expandability.

Individual VCA outputs are available which remove the channel from the main mix (useful for cueing and monitoring). All signals are Euro level and bar the effects return, DC coupled for CV use as well as audio.

Attenuation: approx -70db

Notes: A-135-2 is a miniature version of the A-135-1. Behind a front panel with 8 HP only four linear VCAs (voltage controlled amplifiers) and a voltage controlled mixer based on the VCAs are available.

Controls, In/Outputs and Functions of each VCA:

Level (manual control of the VCA amplification), small rubberized knob (L1...L4)

Control voltage input with associated attenuator (CV1...CV4), for the full VCA control range about 0...+5V control voltage are required (attenuator fully clockwise), for higher control voltages the attenuator is used, the attenuators are without knobs, just plastic shafts with white marker

Signal Input

Signal Output

All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. to control the level of LFOs or envelopes)

The signal input is not equipped with an attenuator. But the VCAs can process all signals up to 15Vpp / -7.5...+7.5V without clipping. In case of higher levels an external attenuator is required (e.g. A-183-1).

The available amplification range is 0...1, the maximal amplification is 1 (i.e. it "clips" and remains at 1 even if the control voltage goes beyond the value that corresponds to amplification 1)

Functions of the voltage controlled mixers:

two outputs ("Selected" and "All")

Selected output: the ouput if a VCA is removed from this sum signal when a plug is inserted into the corresponding VCA output.

All output: sum of all VCA outputs, regardless of inserted plugs into the VCA outputs

The maximal amplification is about 0.6 to avoid clipping at the mixer outputs (otherwise the outputs may distort with 15Vpp signals at each signal input and full amplifications)

Special functions of the voltage controlled mixer (selectable by internal jumpers)

Dual Stereo VCA: In this case the control unit of VCA1 (L1 + CV1) affects also VCA3 and the control unit of VCA2 (L2 + CV2) affects also VCA4. The control units of VCA3 (L3 + CV3) and VCA4 (L4 +CV4) are out of operation.

Quad VCA: In this case the control unit of VCA1 (L1 + CV1) affects all four VCAs. The control units of VCA2, VCA3 and VCA4 are out of operation. In this mode the module has the same function as module A-132-2. That's why module A-132-2 will be discontinued.

Normalling of the signal inputs: by means of internal jumpers signal input 1 can be normalled to signal input 2, signal input 2 to signal input 3 and signal input 3 to signal input In 4. That way the same input signal can be distributed to four different channels by means of control voltages (e.g. quadrophonic distribution of audio signals). Suitable control voltage sources are e.g. A-144 (Morphing Controller) or A-143-9 (Quadrature LFO).

Additional technical specification for each VCA (based on the specifications of the VCA circuits CEM3360/AS3360 used in the module):

Crosstalk between VCAs: typ. - 80dB

Signal attenuation at 0V CV: typ. -70dB

Total harmonic distortion: typ. 1%

Control voltage feedthrough: max. 15mV

Width: 8 HP / 40.3 mm
Depth: 45 mm (measured from the rear side of the front panel)
Current: +40mA (+12V) / -40mA (-12V)

Notes: Osiris is a powerful and neatly packed 12hp bi-fidelity ™ wavetable oscillator with 6+ timbre modes including various waveshaping and phase modulation, an independent sub-oscillator, LoFi processing, extensive cv modulation capabilities, a pitch quantizer, 4 banks of 32×32 wavetables each, the ability to load user wavetables via micro sd card (not included) and it's own free open-source wavetable editor (OsirisEdit).

Osiris is designed to be used as a powerful bi-fidelity ™ wavetable oscillator with an added sub-oscillator. The sub-oscillator has its own v/oct, mix knob, and mono output. If the sub-oscillator output is not patched, the sub-oscillator output is normalized to the mix out. Essentially, the sub-oscillator can act as its own independent oscillator allowing Osiris to be utilized as two separate oscillators.

Osiris was developed in collaboration with Ess Mattisson of Fors.

Timbre Modes
Unison - Layers a second oscillator that detunes from slight beatings up to an octave.
Bend - Compresses the waveform to a thinner shape
Fold - Introduces symmetric 2-stage wave folding by first mirroring the waveform and then folding it
Sync - Repeats the cycle count of the waveform within a Hanning window, making the edges soft
Noise- Adds window-synced noise to the waveform phase
FM x 1 - Applies phase modulation to the oscillator using the same waveform
FM x ....8 - The FM scans through a ratio of 1 up to a ratio of 8 smoothly, with mixed stages in between

Notes: Revised take on the excellent Benjolin dual oscillator and filter from Rob Hordijk, featuring the 'rungler' stepped CV generator and extensive output options.

Supplier's Notes:
Benjolin V2 - Rob Hordijk's latest revision of the classic Benjolin. The core of the Benjolin continues to be two oscillators, the rungler (stepped CV generator), and a multimode filter.

This latest revision adds:

Reworked oscillator and filter sections

All levels are adjusted to eurorack standards

Two different steps modes (8/16 and 127)

Notes: The Stereo Triggered Sampler can record high quality stereo files, while simultaneously playing two different stereo files. A maximum of 600 samples can be loaded from the removable/swappable microSD card, in a variety of formats up to 96kHz/32-bit/stereo WAV. All sample parameters (1V/oct pitch, sample file selection, length, and start position) are CV controllable.

600 Samples:
A maximum of 600 samples can be loaded at once, arranged into banks of 10 samples each. Samples and banks can be re-arranged on the fly using the simple on-board Edit features. Newly recorded samples can be instantly played back and re-pitched, reversed, chopped up, etc... the result of which can even be bounced down and re-recorded to as a new sample! Sample files are limited to 4GB each, which is over 6 hours at 44k/16b/stereo.

Two Stereo Playback Channels:
Each playback channel has a knob and CV jack for Sample File selection, as well as a Start Position knob and CV jack for controlling where in the sample playback will begin. The Length knob and CV jack determine how much of the sample is played back: from tiny grains, to percussive hits, to longer loops... or just the entire file. These are powerful tools for re-arranging a sample, joining multiple samples, and creating dynamically re-sized loops within a larger sample. Combined with the Play Trigger jack and the 1V/oct jack, the STS can be two complete multi-timbral pitch-tracked stereo voices!
There's also a Reverse button and jack for backwards playback, and an End Out jack for synchronizing loops, or cascading sample playback with other events.

Looping and Sync:
Looping is easy: just hold the PLAY button down for two seconds to toggle loop or one-shot. The loop timing clock will output from the End Out jack. Or, send a clock into the Play Trig jack to sync the loop to external timing.

Stereo Recording:
Whether you patched 47 modules to create the ultimate percussive blast, or you want to capture your four hour ambient performance, recording high-quality .wav files on the STS is simple. Just hit the REC button or fire a trigger and a new stereo .wav file will be created on the SD card. Do as many takes as you need: the STS never deletes your files. Re-ordering or re-arranging samples into banks is easy, even without a computer.
You can even fill a bank with 10 different variations and immediately use them for playback.
By default the STS records at 44.1kHz/16-bit, with an option for 24-bit (a future update may increase the sample rate to 96kHz)

Easy sample loading:
Using a computer is completely optional with the STS, since samples can be recorded directly to the module and placed into the bank of your choosing. But for users with large existing sample banks, the intuitive automatic bank loading features make dragging and dropping your entire sample library a snap. You never have to rename your files again!

Notes: Eurorack version of 1010's superb Bluebox. Vast power in 30 HP, with the ability to mix, record and play back in mono and stereo, hook up to a computer over USB for stereo I/O and run effects, all with CV control.

Quasar creates a 3D sound image by binaural audio processing. Two positions named Quasar 1 and Quasar 2 are available, which you can virtually place and move at any angle, height and distance around your head. Room reverb can be added as a further aid to distance perception. The audio signals at input 1 and input 2 can be flexibly routed to either or both positions via an internal matrix mixer. The coordinates of the positions can be set manually or be modulated by internal LFOs or external CVs. For example, you can have sounds orbiting around you, coming from above or below, front or back, and moving toward or away from you. Likewise, a centre position is available as a routing destination that leaves the signal without sonic processing to create a dry/wet mix.

Quasar features two CV inputs which can be flexibly routed to any target inside the module. In fact, each CV can have up to four different targets, which enables a very flexible design of auditory 3D-scenes.

Internal LFOs can be used to add dynamic movement and to create spectacular three-dimensional scenes. There are a variety of standard and advanced waveforms that can be routed to the position coordinates. LFOs can also be triggered and reset by external CVs.

Quasar can add some reverb to the signal. While not being a reverberation module in the first place, Quasar's reverb can improve distance estimation, but also be used to create impressing ambient stereo soundscapes.

All inputs also have digital high and low pass filters, so you can decide which frequency bands go to which position. However, in addition to Quasar 1 or Quasar 2, you can also route the audio to the center position. The center position takes the input signal and distributes it equally to the left and right ears without further processing. For example, you can route the low frequencies to the center position and have the higher frequencies distributed to the outer positions Quasar 1 and Quasar 2. That way, the bass stays centered and mono-compatibility is preserved.

As soon as a three-dimensional virtual scene has been created, it can be saved to the module's preset list. That way, scenes can be recalled at any time. Quasar also features some factory presets as a starting point and to show off the module's capabilities.

The module works best with headphones, as the algorithm basically mimics the shape of the head and the pinnae, which are responsible for our directional hearing. But even if you play the sound through speakers, you will hear a significant difference from classic panning.

As spatial hearing is a psychoacoustic effect that everybody perceives in a slightly different way, Quasar offers several transfer functions for different ear types to choose from. This way, the intensity of the 3D effect can be adjusted to personal needs and fits with the processed audio signal.
With its large aluminum knobs, LED rings, rubber potentiometers and mechanically solid components, Quasar is fun to use and invites creative work.

Notes: The hands-on control of hardware meets the versatility of software. Bridging the gap between Eurorack and VCV Rack, the MetaModule includes over 160 built-in modules plus access to over 200 third-party options.

Supplier's Notes:
The MetaModule puts real knobs and jacks on virtual software modules. Step back from the computer and make music with hardware, while keeping the flexibility and expandability of software.

The MetaModule comes with over 160 built-in modules from 4ms Company, Befaco, HetrickCV, NonlinearCircuits, and Scanner Darkly, plus clones of popular classics such as the Mutable Instruments eurorack modules, fun physical modeling algorithms, and lots of handy utilities.

All of the included modules are also available on the computer using the free program VCV Rack. Whether you make patches on VCV Rack and transfer them to the MetaModule, or if you just create patches directly on the MetaModule, there are plenty of creative modules to inspire new ways to make music.

MetaModule Plugins

If the 160+ built-in module aren't enough, you can load more modules as plugins. Already there are over 200 modules in third-party plugins from Bogaudio, Valley, ChowDSP, NANO Modular, and the list is growing. 4ms have an SDK available to make it easy for VCV Rack plugin developers to convert their plugin to a MetaModule plugin. 4ms' licensing terms are non-restrictive: developers are welcome to distribute their plugin in any way they wish, commercially or not.

Mapping Knobs and Jacks

The MetaModule has 12 knobs that can be mapped to virtual knobs. Each knob can be mapped to up eight virtual knobs, and each mapping can have a different range and offset. You also can save a group of mappings as a Knob Set and switch between Knob Sets with the encoder. You also can map the 8 inputs and 8 outputs to virtual module jacks. Also, the MetaModule is a USB MIDI host, so you also can map MIDI CC, note, gate, and other parameters to knobs and jacks.

Expanders

There are lots of ways to customize your MetaModule. A Wifi expander allows you to wirelessly transfer patches from your computer. Add eight more knobs with the Knob expander, or buttons with the Button expander. A CV/Audio expander adds more high-resolution inputs and outputs, and the Gate In/Out expander adds not only gate jacks but also TRS MIDI and I2C.

Under the Hood

There are six CV/Audio inputs, two gate inputs, and six CV/Audio outputs. The CV/Audio jacks are all 24-bit, 48kHz DC-coupled, -10V to +10V. A USB-C jack accepts MIDI devices and thumb drives. Patches and plugins can be loaded via a USB drive or microSD Card, and internal flash memory lets you save patches you always want to come back to.

The processor is more advanced than anything 4ms has used in the past, and is among the most powerful processors found in Eurorack. Startup time and latency are blazingly fast.

Notes: By combining a mixer and four VCAs in a single module, Mix 3 manages to provide a unique combination of compact size and functionality in just 6 HP. High-end signal paths ensure extremely low noise and distortion, wide headroom and precise gain control, despite the small form factor.

Each of the three main channels has an exponential response, which is more natural for audio than linear, as it matches the human hearing. However, all signal paths are DC-coupled, so control voltage (CV) signals can be processed as well.

What truly sets Mix 3 apart from other compact mixing modules are the three CV inputs, providing voltage control over the signal levels. This even allows you to go beyond unity gain and reach up to +20 dB of amplification. Once a CV input is used, the corresponding channel knob becomes a CV attenuator.

When clipping, Mix 3 does so in a clean, symmetrical way. This yields a very pure overdriven sound, only containing odd harmonics, and allows the module to be used as a triple voltage controlled distortion.

Additional features include audio indicator LEDs, a fourth auxiliary input, voltage control over the output level and a line output jumper setting.

Notes: This is a new build of a micro sized Mutable Instruments Plaits called Knit.

These modules use tall bushing potentiometers to offer a more stable feel.

The module is fully assembled, tested, and calibrated. Eurorack power cable is included.
