Notes: The mmMidi is a simple & compact MIDI to CV interface for your Eurorack synthesiser. It translates both MIDI clock and 2 Channels of MIDI note, velocity and gate information to corresponding voltage control signals. The mmMidi is quick to set up and requires minimal configuration.

Notes: PRO Expanders:

Extra Pam Outputs.

ALM034-EX

PPEXP1 & PPEXP2 are two expander modules for Pamela's PRO Workout that both offer additional dedicated fixed clock, Din Sync & MIDI clock outputs.

Extend Pam as a master to clock external gear with super solid dedicated MIDI & Din Sync clock outputs. The Din Sync clock (x24) and Run outputs can also be patched into a 2nd Pam to easily sync it.

Use the extra fixed clocked gate outputs to free up Pam's main outputs for unique sequencing or complex modulation duties.

Connects directly to and is powered by the 'MIDI-EX' expander header on rear of Pamela's PRO Workout.

Only a single output expander is supported at any time but either can be used alongside an AXON-1 CV input expander.

A MIDI adapter cable and a Din Sync adapter cable are both available for connecting to 5 pin 'Din' type connectors. The PPEXP 1 includes a MIDI Din adapter cable.

Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Features:
Compact envelope and function generator in 4HP.
Trigger and gate inputs.
Voltage and direct control of attack and release times.
Snappy or super long envelope times – ranging approx 1ms to 7 minutes per stage.
Optional self looping ability with 3 different loop modes: Decreasing amplitude, decreasing time, and regular loop.
Shape control that morphs the envelope shape from logarithmic to linear to exponential curves.
End of Slope trigger output that fires a trigger at the end the envelope or loop cycle.
Selectable 5v or 8v max envelope level output.
Reverse polarity protection.
Skiff friendly.
Designed and Made in the UK.

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: 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: Pico DSP is a small brother of the popular stereo effects processor Black Hole DSP. It contains eight algorithms, in detail four delays, two types of reverb, Leslie speaker emulation and an Overdrive/Bitcrusher. Each effect is editable in two parameters. One of them can be modulated using the CV input. Pico DSP features clear, high-resolution sound. Alongside the established standards, it is also possible to generate lots of freaky special effects.

Notes: Pico Drum2 is compact yet versatile percussion synthesizer in a 3 HP eurorack module. It features 8 drum synthesis algorithms created to deliver distinct sounds to your modular system. Each algorithm offers a lot of flexibility therefore a big sounding bass drum and a squelchy snare can be dialled in within the same algorithm. It also tracks 1V/Oct and all parameters can be mapped to the CV1 input.

Notes: Module A-160-2V is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses.

The Clock input will take any digital signal from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.

The A-160-2V also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

HP : 4

Notes: The module contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor) behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V (10V = attack peak).

The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

Notes: The 'MCO' is a compact digital oscillator. It features a main 'morphing' wavetable output, an additional copy of this output with overlaid variable pulse width segments (ala Alpha Juno style saw wave pwm) and a sub square wave output an octave down to the main output. The waveform and pulse segment width and be both directly and voltage controlled. The pulse segment distribution can also be voltage controlled via the 'type' input.

Expect an early 90s slightly crunchy digital type sound (ala Ensoniq, Kawaii KX synths) rather than something striving for perfect analog emulation.

Notes: Module A-147-2 is the successor of the VCLFO A-147 but offers much more features than the predecessor. The module is made of these sub-units:

- VCLFO: voltage controlled low frequency oscillator
- VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
- VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-colour LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.

The CV control can be switched to attenuator or polarizer ("CV Mode" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the centre position. In the centre position CV has no effect and right from the centre the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per period) to 200 Hz (with external CV max. frequency about 1kHz). In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible. For this a jumper has to be installed on the pin header JP6. In the factory a dummy jumper is installed on the pin header JP7 "Dummy". JP7 has no function and is used only for "parking" of the jumper. Simply remove the jumper from JP7 and plug it on JP6. JP6 is located behind the CV control.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).

The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).

The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a green LED and available at the "Delay Out" socket.

The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO)!

The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.

"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.

Notes: A-180-9 is another simple but useful tool. It can be used to connect up to 14 signals between different cases by means of standard network cables (RJ45). These cables are available all over world smoothly in different lengths and colours. From the factory two black network cables with 0.5 m length are enclosed.

The upper network connector is wired to the eight sockets 1-8, the lower to the six sockets A-F. That way it's possible to pre-patch different cases and connect signals, that are required in all cases (e.g. clock, start/stop, master CV) by means of one or two cables only instead of 14 individual patch cables. When only eight signals are required only the upper network connector is required and the sockets 1-8 are used. When more than eight signals have to be patched both network connectors have to be used. It's also possible to wire the upper and lower network to different cases (i.e. signals 1-8 to external case #1 and signals A-F to external case#2).

The module is fully passive (no power supply required) and simply wires the 14 sockets to 14 pins of the network connectors.

The A-180-9 comes in pairs for combining two modular systems.

Notes: HN VCF is a state variable filter having 12 db Low Pass, 12 dB High Pass, 6 dB Band Pass plus 18 db Low Pass marked as "LP!", because it has extra drive. All three parameters: "Freq", "Resonance" and "Drive" have dual knobs with outer knobs controlling bipolar CV amount. These affected CVs are then shown by the relative green/blue LEDs.

The possibility to have CV over "Resonance" and "Drives" makes it a very capable 6 HP filter.

"LP!" output has 6 dB steeper slope (18 dB) compared to ordinary 12 dB "LP" output. Plus it has much more drive.

Notes: Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V. The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR. Changing the positions of the mentioned jumpers allows to modify the factory settings.

Notes: Stmix is a compact 4 channel stereo mixer with an Auxilliar input. This input will allow us to chain a few of them or to insert an extra fifth input.

This module is compatible with Befaco's Hexmix system, and can be internally connected to hexmix module to add the output of STMIX to your main mix.

Notes: The Listen IO is a simple module which gets signals in and out of a Eurorack system by converting to and from normal modular levels. The top section converts any external signal to modular levels by providing up to 30x gain (+30dB), allowing you to use table-top synthesizers, keyboards, phones/tablets, computers, toys, microphones, etc. in your patches. The bottom section does the opposite: modular signals are converted to normal line level signals. The bottom two jacks can be used as line outs or as headphone jacks, so you and a friend can listen in stereo at the same time.

Each section has two inputs and outputs for use with a stereo signal or two mono signals. An LED bar graph for each output shows the signal level and clipping.

Notes: This is the version II of the original uVCA.

This module was adapted from a design by David G. Dixon

Notes: Lipsk facilitates the inversion of the individual bits produced by Drezno (or any other module connected to its input header at the back), and delivers the resulting code to its output header. Bit inversion can be manually controlled by pressing any of combination of its eight illuminated buttons, or it can be automated by patching gate signals into its gate input sockets. An active (5V) gate flips the state of the respective bit. If the button is active (bit already flipped), then the gate flips the bit again yielding double inversion (no inversion). The corresponding LEDs show the combined effect of both manual and gate actions. The bit processing logic is hardware-based, so there is virtually no latency, allowing the binary signals to be manipulated at extreme rates.

Notes: Tune is a multi-scale pitch quantizer. It features 11 scales ranging from chromatic to octatonic with everything in between. In addition, the bias control allows the user to transpose the melody to a different octave or starting note.

This functionality opens up every musical mode for each of its 11 scales and provides a performable control for transforming melodies on the fly.

Notes: Updated expander module for the Moskwa II sequencer. The Ostankino adds additional connectivity to the Moskwa II, allowing CV control of most parameters, plus extra outputs.

Supplier's Notes:
Ostankino II expander adds CV inputs for many Moskwa II functions, as well as a transpose input, clock out and individual gate/bit outputs for each step.

Notes: Gera is a component of the Leibniz subsystem that allows masking individual bits of the digital data by the use of logical AND operation.

It features 8 individual gate inputs that affect the individual bits of data, as well as 8 illuminated tact switches for manual inverting of each control input. When connected to Drezno that is processing a waveform or voltage, masking of individual bits yields various forms of quantization. However, Gera can function on its own. The AND operation is a basic building block for sequence automation, chaos and rhythm generation, and various computer-like modular patches.

Bit processing logic in Gera is hardware based, hence there is virtually no latency, and the binary signals may change at extreme rates.

- X-Y: Alternate graphical display with CH 1 driving the X-axis and CH 2 driving the Y-axis.
- Tune: Alphanumerical tuning display, which you can configure to show either Hz values or note names.

The Scope displays have adjustable display offset for each channel and an adjustable trigger threshold, while the tuner has options for reference pitch and average update speed.
Ins & Outs

The inputs are DC coupled and accept signals between -10V and +10V. The Signal on the input is normalled to the output below; this allows you to monitor or tune a signal without a mult or re-patching.

Notes: FONT is a massive sounding liquid filter- designed to bring you powerful basslines, tons of FM modulation and a clean resonance over your audio path.

It features two simultaneous outputs:
2-pole Low Pass
2-pole Band Pass

It can also work as a sine oscillator, tracking 1V/OCT when the resonance is at its maximum level.

FONT can be used to make basslines, acid patterns thanks to its organic and musically sounding resonance.

Ping it to produce percussion sounds such as, bongos, congas or toms.

Applying a pitch envelope, it really shines as a kick-drum machine!

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: This is a precision active buffer and multiple. This module has outstanding performance: it features very high input impedance, very low output impedance and an offset voltage of <1mV.

Not all active multi's are born equal, some designs do not fully solve impedance mismatch and tracking problems, or they apply offset voltages to the output and in rare cases can cause more problems than they solve!

AJH Synth have added a very useful (and unique) feature to cure tracking problems: four of the five outputs can be adjusted up or down by +/-5% from the front panel, so that VCO's and VCF's that don't track 1V/Oct exactly can be easily compensated to track correctly without having to re-calibrate the VCO or VCF themselves.

Notes: Pico EF is Erica Synths' take on envelope follower module in 3hp! Pico EF features a preamp with +40dB gain (enough to boost even guitar and dynamic microphone signals for use in a modular system), envelope output with adjustable attack time and a gate output with adjustable threshold. The Pico EF can be used as a preamp, overdrive unit or for controlling VCFs with audio signal, or to use with external instruments to control your modular system in other creative and experimental applications.

Notes: Expander module adds four more assignable CV inputs to Squid Salmple for advanced modulation and sample manipulation. A must for all Squid Salmple owners.

Supplier's Notes:
AXON-1 is a 4HP expander module for the SQUID SALMPLE that provides 4 additional freely assignable CV inputs.

The addition of AXON-1 brings Squid's total number of CV inputs to 7, greatly increasing the possibilities for vast modular sample manipulation.

Each modulation assignment includes digital attenuation and offset and behaves just like Squid's 3 built in CV inputs.

AXON-1 requires firmware 166 or later installed on the Squid Salmple to function!

Notes: Think of the MFD like a tiny DJ mixer: two stereo inputs, one stereo output, with the option to cue either input and crossfade between the two. A simple idea very well executed.

Supplier's Notes:
Inspired by DJ mixers, the MFD allows you to cue and crossfade between signals. Ideal for live performance as well as jamming out ideas in the studio.

Supplier's Notes:
The 'MFD' is a 2-channel stereo crossfader designed for live DJ-style mixing and jamming in Eurorack. Two mono or stereo inputs are mixed to a single stereo output via direct or voltage control. Additional Cue controls provide preview monitoring of either input pre-mix via dedicated Cue switches and an output.

Voltage control over the crossfade and DC coupling allow for further creative uses such as a high quality stereo VCA or as a mix processor for either stereo audio signals or CV.

The MFD is designed to have very low noise and cross bleed and employs equal power crossfading for smooth constant level blending between signal sources.

Features:

Two channel stereo crossfader with voltage control.
Approx equal power crossfading.
Cue output switches for direct monitoring of either stereo input (pairing well with HPO for headphone monitoring).
Can be used as a high quality stereo VCA.

Notes: Module A-105-2 is a voltage controlled low pass filter with 24dB/octave slope.

It is the successor of the A-105 which had to be discontinued because the obsolete SSM2044 filter circuit. The A-105-2 is based on the SSI2144 which is in turn the successor circuit of the SSM2044. The features of both modules are nearly the same. The main difference is the clearly reduced front panel width of the A-105-2 (4HP instead of 8HP) and the associated changes of the controls and sockets positions. In addition the A-105-2 is equipped with 2 audio inputs.

The module has these controls and in/outputs available:

Control Frequ: manual frequency control
Control FCV2: attenuator for the frequency control voltage applied to socket FCV2
Control Q: manual resonance control
Control QCV: attenuator for the resonance control voltage applied to socket QCV
Control Input 1 Level: attenuator for the audio input signal applied to socket Input 1
Socket Input 1: audio input 1 (with attenuator)
Socket Input 2: audio input 2 (without attenuator)
Socket FCV1: frequency control voltage 1 (without attenuator, about 1V/oct scale)
Socket FCV2: frequency control voltage 2 (with attenuator)
Socket QCV: resonance control voltage (with attenuator)
Socket Out: audio output
Technical notes:

Frequency range: about 15Hz ... 15 kHz
Resonance up to self oscillation
Max. input voltage at Input 2 without clipping/distortion: about 15Vpp
Max. output voltage without clipping/distortion: about 15Vpp
The signals of both inputs are mixed before they are processed by the filter. This saves an external mixer for small setups.
Depth: 45 mm

Notes: Module A-199 is a spring reverb module. The reverb effect is electronically simulated by means of 3 spiral springs. Spring reverb systems have a very characteristic sound that is based on the (insufficient) mechanical properties of the springs like signal delays, audio resonances, limited frequency range, acoustic feedback behaviour, sensitivity to mechanical shocks and others.

The 3-spring system used in the A-199 ensures a "dense" reverb because of the different properties of the three springs.

The A-199 implies some special features that are not self-evident for spring reverb units:

The reverb signal can be fed back to the input using the Feedback control. Even self-oscillation of the springs similar to the self-oscillation of filters is available. The feedback loop can lead even via external modules like VCA, VCF, phaser, frequency shifter, vocoder, distortion/waveshaper, ring modulator and others. In this case the reverb output of the A-199 is connected to the input of the external module(s) and the output of the external module(s) is fed back to the Ext. Feedback In socket of the A-199. This socket contains a switch that interrupts the internal feedback loop as soon as a plug is inserted.

Another feature is the Emphasis control. This enables the adjustment of the accentuation of middle frequencies (around ~ 2kHz).

With the Mix control the relation between original and reverb signal appearing at the mix output is adjusted.

Using all these features very extreme and unusual effects can be generated with the A-199.

Notes: Each of the two sections of the module is capable of performing the analog multiplication of two signals (A and B) and add an offset (C). It can also act as a dual voltage controlled attenuverter, dual ring modulator, dual VCA or four channel mixer (see block diagram below).

The B inputs are routed to an attenuverter that multiplies the signal between -2 to 2, while the offset inputs (C) route through a unity gain attenuverter (multiplies the signal between -1 and 1).

The output of first section is routed to the output of the second (when the first's output is unused), so the second output can act as master to achieve (A1*B1+C1) + (A2*B2+C2) or (A1 + C1) + (A2 + C2) - a 4 channel mixer.

The through-zero (four-quadrant) multipliers in the A*B+C allow for true Ring Modulation. To achieve this, simply connect two waveforms to the A and B inputs.

Notes: This small utility is the pedal's lover best friend, it allows 2 diferent chains of pedals to be independently connected to your synth.

The Send channels attenuate the synth level to instrument level.

The Return channels amplify the signal from instrument to synth level.

Specs:
- Width: 4 HP
- Depth: 3 cm
- Max current: 10mA

Notes: Verb is a lush stereo reverb with a full feature set and superior audio quality. A wide range of reverb times take your sound from small room to never-ending concert hall.

CV over mix allows dynamic movement between the dry and reverberated sound, and the dampening control lets you dial in the perfect timbre for the wet signal. Whether you need a traditional reverb for an FX send or an esoteric sound design tool, Verb can take you there. Get lost in space with Verb.

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: Module A-160-5 is a voltage controlled clock multiplier. The incoming clock signal (socket Clock In) is multiplied by a factor that depends upon the control voltage on socket CV In (0...+5V) and the position of the Mode switch. The multiplied clock signal is available at the socket Clock Out. According to the position of the Mode switch different clock multiplying factors are assigned to the control voltage. With 0V CV no clock output is generated. This state is indicated by "all LEDs off". With increasing CV integer factors (left position of the mode switch), power of two factors (middle position) or a mix of both (right position) are obtained. Nine LEDs are used to show the currently selected multiplying factor. In addition two LEDs are used to display the incoming and outgoing clock signal.

A manual control is used to adjust the clock multiplication factor manually without the need of an external control voltage. The voltage generated by this control ("Manual") is normalled to the CV In socket. As long as no plug is inserted into the CV In socket the clock multiplication factor is adjusted by means of the manual control knob and displayed by the LEDs. For dynamic applications (like the ratcheting function described below) the manually generated CV is overwritten by the external CV which has to be fed into the CV In socket.

The module can be used for all kind of clock multiplying applications. One important example is the generation of so-called ratcheting sequences. The band Tangerine Dream is famous for this kind of sequences. A normal sequencer generates only one gate signal per step. A ratcheting sequence may have also more than one gate pulses per step. This function can be obtained by using the A-160-5: one CV output of the sequencer is used to define the number of gate pulses per step. If the control of the step in question is fully CCW the generated CV is 0V and no gate signal is generated (mute of the step). When the control of the step in question is turned clockwise one, two or more gate pulses are generated depending upon the position of the mode switch and the voltage generated by the CV at this step.

Technical note: Due to the nature of clock multiplying it takes a few input clock pulses until the clock output is stable. One has to average a few input clock pulses to generate the multiplied clock output signal. Even when the input clock frequency changes it will take a few cycles until the output clock signal is correct as the module cannot foresee the future of the clock input signal. The generated clock output signal is derived from the last few cycles of the clock input signal. Consequently the module should be driven only by a clock signal with constant or slowly changing frequency.

Notes: Clever four-channel utility module designed to make it easier to achieve perfect oscillator tracking and transpose CV signals. Also includes some neat quantising and portamento features.

Supplier notes:
The CalTrans solves issues encountered when playing tonal music with a modular system: tracking problems, curves unrelated to Volt per octave ratio, limited octave range, cumbersome transpose, ...

The CalTrans corrects and expands the range of troublesome VCOs and brings V/Oct tracking to anything that oscillates.

Besides calibration, the CalTrans offers live play features. Each channel can be quantized and any combination of them transposed jointly.

A pair of rotary encoders with detent allow an precise selection of octaves and semitones.

VCOs whose tracking doesn't go high enough to follow the leader will see their pitch repositioned in their highest possible octave so that the global harmony is unaffected.

You can add a pinch of portamento and glissando to each channel and save the whole in user presets.

Notes: Pluck is a physical modelling synth voice. It uses the Karplus-Strong algorithm to create plucked string sounds. The dampening control sets the size of the string and allows for dramatic timbral shifts.

The decay control changes note length from percussive transients to infinite harp sounds. In addition, four voice polyphony provides complex layered tones; all from a single sound source.

Strum a new chord with Pluck.

Notes: Sine is a harmonically pure VCO with two distinct outputs.

The primary output contains a perfect sine wave with a wide frequency range and pristine volt per octave tracking. The Sub output features two sine tones that can be blended together to achieve a mix of one octave below, or a fifth above the primary output's frequency.

In addition, both outputs have an internal wavefolder that adds harmonic content to the signal allowing for spectrally complex tones within a single module. Keep your tones pure (or not!) with Sine.
