Notes: The 4VCLFO is four LFOs with triangle Outputs in 10hp. It features a knob for the Frequency of each LFO and CV inputs with attenuators.

The "Aux" input is normalized to the four CV inputs, so you can modulate all LFOs with one signal at the same time. Plugging a cable into the CV input breaks its connection from the aux input.

This way you can create more interesting Modulations for your Patches.

You can easily customise LFO speeds to your liking by changing capacitor values on the back.

Notes: The Exhaust adds many features to your Engine V2 VCO module like Sub-octaves, Mixing and a Gate / Trigger generated by the Chaos signal.

You can select one of the two VCO cores of the engine to Produce Square Waves one and two octaves below the Oscillators frequency. You can blend between -1 and -2 octaves and Set the volume they are Mixed into the Main "Mix" output.

The knobs "VCO1" "VCO2" and "AM" set the level of the selected waveform of each VCO and the AM output from the Engine to the Main Mix. The "Ext In" Input is normalled from the RM output, but you can plug in any other signal to go to the Main Mix.

The V Ref sets a Voltage between 0V and +10V which compares against the Chaos signal from the engine (Chaos attenuator on the Engine doesn't matter). Whenever the Chaos signal is higher in Voltage than the Knob setting, It will Give you a Gate or Trigger signal depending on the switch. There is also a CV input, which offsets your V Ref and can create interesting Rhythms.

Features:

Two Sub-Octave generator with selection switch, Mix knob for -1 and -2 octaves (marked as /2 and /4)
5 Channel Audio Mixer for 4 different Outputs from the Engine and level for the Sub-Octave generator
External Input for Mixing with other signals

Notes: VCFA - Voltage controlled Filter and Amplifier

The CubuSynth VCFA is a multimode VCF with LP,HP and BP modes with integrated VCA, CV control over Frequency, Resonance and Volume.
The CV input for the Frequency features 1V/Oct scaling over about 2~3 octaves. So you can even create plucky melodies
with the resonance in "ringing" mode.
The Gain control can reach a nice, soft saturation.

Key features

- 3 simultaneous outputs for Low Pass, Band Pass and High Pass
- Integrated VCA on input stage
- Input saturation on upper Gain levels
- CV control over Volume, Frequency and Resonance
- Frequency CV scalable for 1V/oct signals (stable up to 2-3 octaves)
- "ringing" appears on upper Resonance levels

Notes: The CubuSynth ADSR Module is a VC looping envelope generator, with controls for the Attack, Decay, Sustain and Release stages, for overall Time of the envelope and CV inputs for Time and Level.

The EnvGen8 chip was written/designed by Tom Wiltshire aka "Electric Druid".

1 ATTACK (1ms - 10s)
Sets the time, the Envelope takes to reach full level from the moment a gate is detected (Key is pressed)
2 DECAY (1ms - 10s)
Sets the time, after the envelope hits full level, to fade to the level set by the SUSTAIN Knob.
3 SUSTAIN (0% - 100%)
Sets the Volume to stay after the decay, while the GATE input is high.
4 RELEASE (1ms - 10s)
Sets the time for the fade out on falling edge of the GATE input (after the Key is released)
5 MODE switch
Select between exponential and linear curves.
6 PUNCH switch
Adds extra thump to very short percussive envelopes
7 LOOPING MODE switch
Allows selection between three different modes of operation. Gated mode is a normal envelope. Gated Looping will
trigger the ATTACK stage when the GATE goes high, then continue looping whilst the GATE remains high, and will
RELEASE to zero when the GATE goes low. The LFO Looping mode loops continuously and ignores input from the
GATE.
8 TIME (x1 - x100)
Overall Time control which shortens the length of the entire envelope.
9 TIME CV Attenuator
Attenuates incoming CV for Time modulation. Higher voltages will shorten the
length of the envelope.
10 TRIG Input
Re-trigger for the envelope. Useful for Polyphonic patches. Envelope goes to
ATTACK stage on rising edge of 0-5V pulse while Gate can still be on.
11 GATE Input
Normalized to TRIG Input. Envelope goes to RELEASE stage on the falling edge.
12 Level CV Input
Control the overall Volume of the envelope. Can be used for velocity control.
If nothing is plugged in, the Volume stays on max.
13 OUT
CV-output of the envelope (0 to +5V)
14 LED
Indicates the output voltage.
15 TIME CV
CV Input for Time modulation. Higher voltages will shorten the length of the
envelope.

Notes: This is a self contained analogue high hat module. This is a Transistor based VCA design. It is influenced by the DR110 drum machine. The original circuit used 4 oscillators to make the metallic audio sound. I added the original 4 oscillator, and an extra 6 oscillator circuit. The 6 oscillator version is doing a double XOR ringmod (internally). You select that by switch.

The 4 oscillator design sounds more crunchy, where as the 6 XOR circuit sounds more polished with sheen. You can blend in the amount of white noise in the mix labeled 'sizzle'.

Internally, the audio is passing through a few high pass filters, making the output sound very high in frequencies.

The module by itself is not exciting. But in the mix, with other percussion modules, this is your favorite-go-to module. It sits almost perfect in the mix.

There are two triggers. One is for 'Open' sound. The other is for 'close' sound. Both open and close have there own decay knob to adjust the length of the audio tail.

There is a tone control, labeled LPF. Use this to taper off some of the high frequencies.

Instead of adding an 'accent' control. Both triggers have been made to voltage variable. 5V triggering is the normal expected input. So a 3V trigger will sound softer in volume. 10V trigger signals will sound louder.

This module is as simple as it gets, just patch your Arturia Beat Step Pro and use the drum track.

Features

-Both trigger inputs are voltage variable. You can get softer audio, with softer trigger voltage.
-2 voice metallic noise generator
-2 decays (open and close)
-2 Flavors select by switch.
-Normal mode, and Sustain mode, selected by switch.
-frequency adjustment of the internal XOR ringmod.
-classic roland sounding transistor based VCA.

Why get this module over the Shimm module, or other high hats modules?

-Ease of use, ready to go. No sound exploring needed.
-Want the classic transistor based, crunchy sound.
-lower budget
-Sits very well in the drum mix.

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

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

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

Features:

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

Notes: 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: 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: Sometimes your ears are not enough and you really need to see the sounds and control voltages you are generating. Zeroscope's two channel design lets you display and compare both control voltages and audio. It's a good old fashioned sci-fi light show!

The Zeroscope 1U is an adaptation of the excellent 3U Zeroscope by VPME.DE.

Three Modes Packed Into 1U:

- Scope: Standard graphical display, with time displayed on the X-axis and voltage displayed on the Y-axis.
- 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: Erica Black Series include high-end, unique functionality and superior quality modules. Only the best, highest quality components are used, all inputs and outputs are protected against undesired overvoltage. When designing Black Series, put Erica Synths prioritised design and usability first Big knobs are assigned to functions that make difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy!

The Erica Synths Black Dual ASR EG is a versatile, full analogue voltage controlled looping envelope generator and low frequency oscillator with manually and voltage controlled shape and rate, designed for use in advanced modular systems.

It has two identical parts, each featuring all typical envelope generator controls and bonus features - the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).

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.

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: The CP909 is the TR-909 clap sound analog generator in Eurorack format. This is yet another low-cost analog drum generator from a legendary drum machine in your modular synthesizer, expanding your Tiptop Audio modular drum machine even further.

The CP909 is an exact reproduction of the original analog circuit and, with the addition of just one extra knob, "trashing" the frequency of the internal noise generator, we have added greatly to the spectrum of sounds that can be generated - all that without compromising the signature sound of the TR-909 clap.

The CP909 clap effect is made by a special triple-saw envelope generator that controls the gain of a VCA. The sound source feeding into the VCA is made by a quasi-random logic based noise generator; some might call it "digital noise" though this term might be misleading in today's world of microcontrollers and sound samples. What really makes the noise generator is a ring of logic gates, so primitive, so BO's, and that's the sound of the 909 Clap!

The CP909 includes a high-powered output gain stage capable of producing hot signals. On the inputs, we have designed a pulse-shaper circuit so you can trigger the CP909 with trigger/gate signals from step sequencers, clock dividers, or any other pulse/clock sources. This eliminates the need to shape pulses sent to the module and ensures the same stable sound at peak power, regardless of your pulse source. Based on the architecture of the 909, the Accent input is versatile and able to take in both CV and Gate signals for continuously changing dynamics. All these unique features make integrating this legendary sound generator into your modular synth easy, unleashing the power of real analog drums.

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: 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: A simple noise generator and 4 band fixed filter bank.

The noise is normalled to the Filterbank input. The cutoff frequencies are matched to the Bark Filter, so that four bands of the Bark Filter correspond to a band on the Noise & Filter.

It is a small and quick noise source and pairs well with Scan & Pan and Amp & Tone.

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: Module A152 is a very useful switching and T&H module. It combines a voltage addressed 1-to-8 multiplexer and 8 fold T&H that can be used as kind of an analogue shift register too. The active in/output is displayed by a LED. The digital output of the currently addressed step outputs "high". The remaining digital outputs are low.

Instead of voltage control even clock/reset controlled addressing of the active step is possible. The rising edge of each clock signal causes an advance to the next state. The rising edge of the reset signal resets to step 1.

The sum of the voltages coming from the manual Address control and the CV input define the currently addressed step of the 3 sub-devices. If the module is controlled by clock and reset the control voltage has to remain unchanged as the CV control has priority over the clock/reset control (e.g. simply turn the CV control fully counter-clockwise and do not touch the Address control knob).

Sub-device #1 is the bidirectional 8-fold multiplexer (kind of an electronical 8-fold rotary switch). Bidirectional means that it works into both directions like a mechanical rotary switch: the common socket may work as an output that is connected to one of the 8 inputs that are e.g. connected to modulation or audio sources. But the common socket may even function as input. In this case the signal applied to the common socket is output to the currently addressed single socket. The voltage range of the in/outputs to be switched is the full A-100 voltage range -12V....+12V. All A-100 signals can be switched without any restrictions.

Sub-device #2 is the addressed 8-fold T&H. The signal at the common T&H input is connected to the addressed T&H output. As soon as a new output is addressed the last voltage is stored at the output (Track&Hold function). The T&H section of the A-152 allows the emulation of the "toggling T&H" function of the Buchla module 266 "Source of Uncertainty". Only the first two T&H outputs of the A-152 are required for this application. This unit can be used also as kind of an analogue (shift) register. The difference to a "real" analogue shift register is that the sampled output voltages are not shifted to the next output but remain allocated to the same output. But in some cases (e.g. controlling the pitch of 3 VCOs by 3 output voltages of the A-152) the result is the same.

Sub-device #3 is the digital output section. The digital output of the currently addressed turns to "high". All other digital outputs are low. The digital outputs can be used to trigger e.g. envelope generators or to control the reset input in the clocked mode to reduce the number of addressed stages.

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: 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: 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-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: The Beautifier is a flexible OTA based filter, featuring a lowpass/bandpass switch and a selectable slope of 24db and 12dB. Two attenuated CV inputs for frequency cut-off and resonance. The filter self-oscillates at a given point and can be driven quite hard if you crank up the gain. All in all, a versatile analogue workhorse with a lot of character; from smooth and creamy to quite raw and screamy.

Notes: The SVF is a 4hp 2 pole 12dB State Variable Filter Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It provides Low Pass, Band Pass, and High Pass outs inspired by WASP and Thomas Henry filter topologies. The filter has 2 audio inputs, but channel 2 is jumper selectable between standard audio in or Ping-able operation. The 2019 revision also adds improved cutoff and resonance response and attenuversion through the ACV IN using the above pot. CV IN provides another unattenuated voltage input to modulate the frequency.

At the CV in, +10v will open the filter completely if the cutoff pot is CCW(counter clockwise). With the cutoff knob at noon the filter can be opened with +5v or closed with -5v. CV input at the ACV in is dependent on the CV attenuverter knob.

There are also several jumper selectable modes for max resonance, self oscillation or no oscillation based on the setting of the resonance pot. According to the jumper configuration, the filter is capable of clinical and clean, to juicy and drippy, to low pass gate sounding plonks, to screaming chaotic resonance. When set to self oscillation mode, the filter can produce a sine like wave with no input and a trapezoid like wave in the max resonance jumper setting. In max resonance mode, the filter output can exceed 10Vpp. On the newest version, there is a trimmer on the top pcb to set the lowest cutoff frequency.

The new black and white pcb/panel is reversible meaning, one side is classic (first picture) and the other side is soulless (second picture).

Notes: The Fold Processor is a voltage-controlled wave multiplier and sub-octave generator. The circuit is based on a classic diode design that adds odd harmonics by folding the incoming signal, followed by subdivided square waves.

The wave folder creates new waveforms from standard sine, triangle, sawtooth, and square waves and includes a CV input with an attenuator, making it very easy to create beautifully animated folding sounds. Adjustable voltage-controlled Inject alters the bias point creating an even wider palette of sounds.

The subdivide generator squares the fold output generating 4 more sounds spaced one octave apart, each with its own gain knob and mixed to the Subdivide output jack. Mixing the four can create anything from discordant square wave swarms to sweet harmonic oscillator stacks, from a stable square version of the folded wave to freaky PLL-like glitched slides.

Overall results can sound evil at times and sweet at others, a true multi-faced devil.

Notes: Clever FM module that does digital-style through-zero FM using analogue circuits. Use any signals from other modules as your carrier and modulator, then phase modulate or wavefold in the FM Aid.

Supplier's Notes:
FM AID is a module designed to perform through-zero linear Frequency Modulation (FM) in the analog modular world. Any arbitrary signals can be used as a Carrier and Modulator. The module copies FM in how it is done in digital implementation, but in a completely analog circuit free of digital aliasing artifacts. Digital or software FM oscillators are mainly based on a ramp waveform which is then shaped to other waveforms. This is also represented in the FM AID module: sawtooth signal is expected on the Carrier input to give the indicated sine, triangle, sawtooth and square waveforms on the respective outputs. However the user is not limited to only use sawtooth for the Carrier and any other signal can be plugged giving many complex waveforms at the outputs.

All known FM tricks from digital implementation are also applied - you can endlessly experiment with the Carrier/Modulator frequency ratios, Modulation index (FM knob), Modulator's amplitude shaping (CV knob), feedback FM (output is fed back to the Modulator's input) and many other.
Carrier input has normalled connection to the Modulator's input. This internal routing is disconnected each time a plug is inserted in the Modulator's input. That is a handy option which allows the module to be used with only one signal source - this single signal will act as Carrier and Modulator at the same time. There won't be any frequency differences between Carrier and Modulator in this case, but many interesting wave folding sounds will be available anyway.

Technically speaking FM AID uses Phase Modulation, not Frequency Modulation. The sonic difference is that the produces sound is brighter.

Notes: Sindikat is made to be placed in the heart of every modular setup: copy, invert, attenuate, scale, get different polarity versions simultaneously of two pair of mixes, mix CV as well as audio (up to 8 sources in total), mute or switch to add desired source to a bigger unity mix, scale two separate mixes with chosen gain.. All circuits can preserve their independent use and/or be combined!

Details & use:

The module consists of circuits designed to group the most useful operations for signal mingling in modular synth setups -but in the more fun manner!

It is designed in the way that the circuits can function independently -be patched to the other modules- or to be combined inside the module at the same time!

On the top of the module there is a buffered multiple (the bi-color led is indicating signal input and its polarity) : Next to the input there are two outputs giving the exact copy of the incoming signal. On the third output you'll get the 'attenuverted" version of that signal which is controllable by the dedicated attenuator/inverter potentiometer.

This signal can be further added (or muted) via its switch, internally to a unity gain mixer situated on the bottom of the module via its SUMM OUT.

This mixer has its own 3 inputs who will accept CVs as well as audio signals with an output gain of 1/3.

Its bi-color led will indicate the polarity of the incoming signals.

In the center of the module there is a CV Processor consisting of two mixers each mixing two signals- in the way that:
The first one takes two signals (A and B) and outputs simultaneously the positive version of their mix (AB+ OUT) and the negative version (AB- OUT).
Their gain is scaled by the potentiometer: going on 1x in the middle position to 2x fully turned. (After middle position with a stronger signal and due to higher gain it will start to saturate producing an distortion-like effect)
Further, via their switch, those mixes also can be added to a unity gain mix (SUMM OUT) and therefore creating a larger mix.
You'll do that by choosing which polarity output you want to send to a summing mix.
In the middle position of the switch the signal is "off" so you can use this to mute/un-mute the signal in the unity mix. Also, even if it is in "off" position this only breaks the internal link to a unity mix but you can still use their distinctive outputs to send your positive and negative mixes elsewhere in your system.

Goes the same for the second one: C and D inputs giving positive (CD+) output result and negative (CD-) simultaneously , all with gain select and the switch choice for summ positive or negative (or none) to a bigger unity mix.

You can also choose to use those two circuits as a simple attenuators for ex. by patching only one signal so you'll get an attenuator and polarizer at once!

The module can process CV and audio as well in every circuit.

Therefore, by summing eventually all the signals to a final "SUMM OUT" output you can create up to 8 sources -in the module- large mix!

Made for more fun with a modular!

This module fits perfectly well with Modulaire Maritime "Decca" switch-based manual control module.

As these modules are developed from practicing recording in "one take" (same for a live performing), combining them you get an extended control over CVs, gates and audio going on in the system, allowing to switch- stop/mute, change polarity, introduce/mix more gates, drums,.. on the fly.

Notes: DVCA

DVCA is a dual VCA based on the Mutable Instruments Veils. It features two separate voltage-controlled amplifiers, both with a gain and a response curve potentiometer, that is variable from linear to exponential. The outputs are normalized, so when no patch cable is present on output 1, output 2 will contain both signals, allowing the module to be used as a mixer. Several DVCAs can be daisy-chained for voltage-controlled mixer operation. It comes with jack lights that can be disabled via a jumper on the back.

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

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

Notes: Dual xFade is a compact voltage controlled crossfader suitable for both audio and CVs. Smaller knobs set manual crossfade between A<>B, and bigger knobs are CV attenuverters. LEDs show the adjusted positive and negative CV sides for easy monitoring.

Upper inputs (section 1) are normalled to lower inputs (section 2). Thus the same signal pair A&B can be differently crossfaded in both sections.

The switch clones section's 1 controls to the section 2, which is useful to make stereo Dry/Wet adjustment or stereo VCA.

This module can be used as:

two independent crossfades

two independent VCAs

stereo crossfade or Dry/Wet control

stereo VCA

panner

Four jumpers on the back can give optional 5x amplification for each A or B input. Sot it is easy to crossfade modular level with linear level from pedals. Installed jumpers give 1x amplification, removing jumpers gives 5x amplification.

Output 1 is mixed with output 2 if left unconnected.

Notes: Incredible sounding VCO module that helps you get incredibly rich signals out of your synthesizer. The Dreadbox Hysteria VCO features a huge frequency range of 16hZ to 32kHz. This gives you a lot of functional pitch to work with, allowing you to explore the sounds capable from this module.

The sounds themselves rest on a variable waveform selector - meaning you can scroll through the waveforms and blend them together. This can even be CV controlled, so you can obtain an evolving sound that changes over time. The modules in the Chromatic series give you a great starting point in the world of modular synths and are a must-have for beginners and professionals alike.

Notes: This new module should not be judged by it's size, at 6hp it's packed with features.

At its core it features a noise source and two precision Sample & Holds with 0.01% of maximum deviation from the Input which allows for quantized signals to be sent through without any noticeable detuning or the typical voltage drops over time.

The Sample & Hold sections can also be used as a Track & Hold meaning it holds the incoming input while the Trigger input is ON and lets the input flow to the output when the Trigger input is OFF.
Each section also features it's own slew processor with a single control over attack and decay and an ON/OFF switch.

The noise signal is normalled to both sections inputs, meaning that without a jack plugged into the Input the sample and hold function will act upon the incoming noise signal generating random CV values.

The [Trigger A Alternate] switch allows to Link both sections so that any trigger input in Trigger A will alternate between triggering the A and B section.

Besides each section outputs there's also 4 extra outputs: Noise, Difference, Average and Sum. The Noise output is coming from the noise source, the Difference output is the subtraction of section A minus section B, the Average output is the sum of both A plus B and then divided by 2 and finally the Sum output is the sum of both A plus B sections.
