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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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.

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: 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: 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: Theremin module for generating a variable control voltage by approaching/removing hand to/from an antenna. The distance range is about 30-40 cm. Additionally the module is equipped with a Gate output with adjustable threshold level. Controls/Inputs/Outputs: antenna input, offset (knob for zero adjust), 2 x CV out, 2 x LED (for CV control positive/negative and zero offset adjust).

To simulate the original Theremin two A-178, a VCO (e.g. A-110) and a linear VCA (e.g. A-130 or A-132) are required. But of course the A-178 can be used to control other functions in the A-100 (e.g. filter frequency, modulation depth and/or speed, tempo, attack/decay time and so on).

The CV output voltage of the A-178 can range - according to the setting of the front panel controls - from -10V...+10V. The gate output switches from 0V to about +10V.

Applications:

- Controlling any voltage controlled parameter of the A-100, e.g. pitch or pulsewidth (VCO A-110), loudness (VCA A-130/131/132), panorama (A-134), filter frequency or resonance (A-120/121/122/123), phasing (A-125), frequency shift (A-126), resonance peaks (A-127), envelope parameters (A-141/142), tempo (A-147)

- Triggering of A-100 activities via gate with adjustable threshold, e.g. starting an envelope (A-140/141/142), Start/Stop of a sequence (A-155), any switching function (A-150/151)

- Conversion into MIDI control change messages is possible with the A-192.

If two or more A-178 are used the distance between the modules/antennas should be at least 40-50 cm. Otherwise the antennas may affect each other.

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: Welcome to the Forbidden Planet, an all analogue multi-mode filter design influenced by the 1975 Steiner-Parker Synthacon model. Control the Forbidden Planet manually or through CV and take the sound of your Eurorack into new orbits.

Forbidden Planet has three filter input jacks: High Pass, Low Pass and Band Pass. The High Pass section is this module's signature sound - a crisp sharp-cut with no residue, designed to add High Pass filtering capability to Tiptop Audio's wide range of Eurorack modules. Send a throbbing kick drum through the High Pass section and filter out the rumbling lows while maintaining the pulse of the beat. The Bandpass is clear and useful in isolating a pie-slice-range-of-frequencies while cutting off the low and highs, great for accurate sound design or sculpting audio into that sweet spot. The Low Pass is an airy classic 12db two-pole analogue slope ideal for monophonic synth patches and filtering down to the essential low-end bass we all love.

The Forbidden Planet Resonance utilizes an internal feedback path which can sound smooth or aggressive depending on the knob setting. At a low setting, it emphasizes the cut-off harmonics, at middle settings it begins to self-oscillate, and towards maximum setting it forms interesting tones and all sorts of chopped grainy bits of self-oscillation perfect for entering into a sci-fi world.

The Forbidden Planet is an impressive multi-mode analogue filter which adds a broader filter spectrum to the Tiptop Audio modular family and unlocks forbidden creative possibilities in a small package.

Notes: The ZONE B.F. module is an element of the Capsule TITAN. Zone basses frequences stands for low frequency zone. This module is composed of 2 LFOs, both LFOs have 16 sync-able waveforms.

Speed : speed of the LFO, range from 0.1 Hz to +/-200 Hz
Wave (LFO 1 & 2) : 16 Syncable waveforms

The ZONE B.F. (black edition onwards) now features an additional mode. On the back of the PCB you will find two jumpers, marked as JP1. CV1 is LFO channel 1 and CV2 is LFO channel 2. By moving the jumper so it sits on one leg (rather than 2 as when you have received the module), the Sync input for either LFO channel now becomes LFO speed input, controllable via CV.

Tech Specs

- SYNC 1 & 2 : LFO waveform is reset when an impulse signal is received
- OUT 1 & 2 : LFO signal outputs 1 & 2
- Voltage swing is -/+5V
- LEDs display LFO activity

- Consumption: +12V 40mA, -12V 10mA

Notes: Introducing the SD808, part of our new series of drum modules that brings analog percussion to the modular synth world, instantly turning your system into a self-contained music machine.

The SD808 is the TR-808's analog snare drum circuit adapted for use in Eurorack modular synthesizer format and was designed to sound like a fresh-out-of-the-box, 1980s TR-808 snare. Adapting the circuit to the modular format has allowed us to add special features like independent accent levels, a high-powered gain stage, a dual-input pulse-shaper, and an adjustable noise source - all without compromising the signature sound of the TR-808 snare drum.

The SD808 sounds tight and extremely snappy because it's analog - the real thing, not samples. The sound is made with three analog sound generators mixed together: two oscillating sine waves and a noise source. The SD808's front panel controls have a lot of sweet spots with sounds that are not just limited to snare drum sounds; it can also create other electronic percussive elements.

The noise source generator in the original TR-808 machines were revised in later production batches, resulting in variations in sound across the production run. The SD808 uses this later, revised circuit to create a snare drum hit that is slightly darker, has more body, and is more realistic. Just like other drums in this series, the SD808 includes a high-powered output gain stage capable of producing signals up to 20Vpp, allowing you to get an array of harmonized snare drums sounds with even tighter attacks. On the inputs, we have designed a dual-input pulse-shaper circuit so you can trigger the SD808 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. All these unique features make integrating this legendary sound generator into your modular synth easy, unleashing the power of real analog drums.

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

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

Notes: The 8S is an 8 step sequencer in 8 HP with control over some parameters of the sequence as reset, hold, random step and direction. The inputs have been designed to work with clock related signals like triggers or gates but any type of CV signal can be used. The output signal path is completely analog and its range can be set to unipolar (0 to +5 volts) or bipolar (-5 to +5 volts) via jumper on the back of the module.

Notes: Strom+ is a strong, reliable and safe 4HP power solution for your modular system. The Strom+ power module includes many safety mechanisms to prevent your modules from being damaged. These include most importantly short-circuit protection, overvoltage protection and a replaceable main input fuse. See the full list below.

Strom+ also offers a current sensing technology that indicates current consumption of your system. LEDs of each rail will turn orange then red, when current consumption reaches or crosses the maximum load of that rail.

Strom+ has extremely low ripple, even under full load. This means better sound and stability for your modules.

One module can power multiple skiffs via Strom Passive Module, a Strom Connector Cable, or a KOMA Strom Busboard.

Notes: Taking equal inspiration from gritty delays on cheap mixers, the sounds of dub and the fracturing of consciousness in time and space, the Coma Reactor looks like a deceptively simple delay module... till you start digging deeper.

The Coma Reactor boasts the crunchy sounds of the PT2399 chip, but adds a number of useful routing possibilities that really open it up for sound mangling that transcends the norm.

Independent volume controls for dry, wet as well as FX loop return allow you to blend in clean, delayed and affected sounds to suit your needs. A CV input on the module increases or decreases the delay time, going from slight tape-echo warbles to some truly seasick pitch shifting. A buffered clean through allows you to pass an unaffected unity gain to a mixer or other device.

The Send/Return path allows you to process your delay signal through another effects unit. Without anything plugged in, a truly nasty bandpass filter lurks in the delay feedback path. The 2022 edition of Coma Reactor features Frequency (CV controllable) and Resonance knobs for this filter.

Lastly, this completely delirious module is also capable of generating noises and oscillating with no input attached, making it a useful soundtrack generator for the end of the world.

The 2022 Coma Reactor includes a breakout header for future integration with upcoming AFA expander modules.

Notes: Unlock the potential of the Quad LFO with the LFO Phase Expander. Each expander gives you three outputs that duplicate the LFO with a fixed phase difference. The first ranges from 0- to 180-, the second from 90- to 270-, and the last from 180- to 360-. Along with the original output, this gives you four phases of modulation. These are easily tuneable to quadrature (all knobs centred), but also any arbitrary phase relationship. You can attach up to four expanders, one for each LFO, giving you up to sixteen modulation sources.

A multiphase LFO is extremely useful for building rhythmic modulations, particularly when paired with analogue logic, such as provided by Babel. Further, regardless of the waveform selected on the Quad LFO, the output of the Phase Expander is always a sine wave. This gives you the useful possibility of having three rhythmically related phases of an LFO synced to a clock signal.

Other than rhythmic modulations, the most common use of a multiphase sine LFO is in creating panning and crossfade controls that sound correct using only one or more VCAs. This is useful in panning sounds back and forth, rotating a sound in quadraphonic space, creating Shepard tones, etc.

Even when you don't have a specific need for exact phase relationships, a multiphase LFO gives you a convenient way to expand your palette of potential modulators, adding three related but distinct waves.

Notes: QMS does quadraphonic mid-side processing. Given a left front, right front, left back, and right back signal, it produces a mid and three side signals: left-right, front-back, and cross or diagonal. Then given these latter signals, it again produces left front, right front, left back, and right back. It has intelligent normals for passthrough, -6dB lowered mid and side signals to avoid clipping, and is equally useful for stereo mid-side when quadraphonic is not available.

Rather than merely creating an image of a sound, something that you passively look at, this module allows you to create a sonic texture that fills a room. Listening becomes active exploration instead of passive observation. Ambient music is all about space. But stereo can only provide a passive experience of this space. It's like there was a wonderful landscape glimpsed from a train window, and many experiments in stereo imaging attempt to reproduce the experience of being in that train, looking through that window. With quadrophonic sonic textures, you get to leave the train and run with the caribou.

Notes: Babel is a tool for creating massive intermodulation, and a workhorse for analogue logic, depending on your use and interpretation of its function. It provides three inputs, which can be arbitrarily increased with the chainable expander (see below). For each of those inputs, Babel outputs the maximum value (ANY), the minimum value (ALL), and the balanced middle value (XSOME), which follows along the centre values of the input waves. What CENTER means is adjustable via knob and CV control. XSOME is particularly interesting, as it has the same general shape as a multiplication function, but with sharper edges. What this means it that Babel will create ring-mod like intermodulation-but with extra harmonics like those produced with a wavefolder, and with an arbitrary number of inputs, instead of just two.

When viewed as a logic module, Babel takes any group of truth values and tells you whether any of them are true (ANY, the equivalent of "or" with just two values), whether all of them are true (ALL, the equivalent of "and" with just two values), and whether some, but not all of them are true (XSOME, the equivalent of "xor" with just two values). Turn CENTER all the way to the right for 0-+5V logic, or leave it cantered for -5V-+5V logic-handy when your "logic" modules are really LFOs.

Notes: The New Systems Instruments VCA module gives you four well-calibrated VCAs in 6HP. These VCAs use operational transconductance amplifiers (OTAs) at their core, for true linear operation. However, unlike most OTA VCAs, the New Systems VCA is extremely low noise and distortion, coming in at < 0.2%, with ~0.05% typical.

There's no such thing as "transparent," particularly in synthesis, where the concept of an original signal that could be faithfully reproduced is often altogether absent. In a VCA in particular, a desirable envelope response can be even more important than accurate reproduction of the input at some fixed level.

The New Systems Instruments VCA has an extremely neutral, open sound. The envelope response sounds noticeably fast and accurate. If you want a dirtier VCA, stay tuned. New Systems are in the process of designing a different VCA with some control over signal and envelope linearity.

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: 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: 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: 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: This module is a 8 ins and 8 outs precision buffered matrix.

Every output has a rotary switch to select an input. You can make the same input go through several outputs but not several inputs go to the same output.

There's also a bicolor led next to every switch for visual info of the signal that is going thru it.

Allows fast patch changes and easy rerouting signals, both audio and cv.

Can be used as a traditional buffered multiple, pretty flexible one: 1 x 8 outs, 2 x 4 outs, 4 x 2 outs or any other combination.

Notes: Nice dual-module gate/envelope generator which can run off any audio signal. Feed it drums, synths, samples or a mic input and and generate CV modulation signals.

Supplier's Notes:
The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source.

Converting microphone, instrument, line and modular signals into CV and clock/gate signals, the PI and PI Expander are suited for synchronizing sequencers or other modules to the rhythm of an audio track or live percussion. The modules can simultaneously be used as a pre-amp for microphones or line-level signals, while generating inverted envelopes useful for side-chaining. The PI module contains all the core functionality and can be used without the Expander to conserve space. The Expander requires the main PI modules and adds three gain stage options, a modular-level audio output jack, a 1/4" (6.35mm) input jack, and envelope attenuation capabilities. The two modules are only sold together, they are not available separately.

Notes: Play is a high-fidelity sample player with a full feature set.

Up to 32 samples can be loaded at a time and dynamically switched between using the file knob and associated CV input. Playback modes include one-shot, looping, or gated playback; all with extremely low latency. Transform your samples by pitching them up two octaves or down three octaves, all with a pitch knob that can be free running or quantized to semitones. The pitch CV input tracks volt per octave across its entire range and allows for musical sequencing of samples. Play ships with a pre-loaded SD card packed with loops, drum hits, and field recordings to get you up and running immediately.
