Notes: The Circadian Rhythms is moving modular synthesizer technology another step forward by gluing all the pieces of a system together. Each module or voice can now be programmed to play straight from an intelligent, eight-channel, 512-step master trigger sequencer made for composers looking to make music on the modular. Building on the sequencing concept of step programing multi-channel patterns of musical phrases can be repeated, looped, chained, muted and manipulated on the fly in real-time, and most importantly, all of this is done through a simple, clearly labeled interface. Using an array of multicolor illuminated buttons and innovative grid views provides a highly functional live performance sequencer with a beautiful glowing appearance of the programmed music that will look amazing on stage for both performer and crowd. As a master controller, the heart of the modular synthesizer, Circadian Rhythms generates high precision clock and reset signals for all the other sequencers and devices in the system to align with and can also act as a high precision bridge for DAW synchronization.

Views - Unlike most hardware sequencers that have a single static display of a timeline, Circadian Rhythms offers four different horizontal views of the timeline and two unique vertical views that scale from macro to micro. Switch between viewing 64 steps at once or all 8 channels side by side instantly. Stretch gates over multiple patterns to drive envelopes or use Zoom view to move a single hit back a few milliseconds in time to get the right feel all from the same interface.

LED Grid Built for Quick Access - Built around 72 buttons set as a multi-color illuminated 8x9 array, Circadian Rhythms displays both note data and settings in a clear and precise manner. It takes only one click to switch to vertical view and the grid turns into a set of programming and realtime playing functions like Mutes, Loops, Swing, Fills, Copy and Pate, Grouping, Randomizing, Manual trigger entry drum machine style and many many more. Activate any of those functions with only a button press or two.

Clock - Inside the CR ticks an extremely precise clock with jitter and latency measured in mere microseconds for the ultimate feel of groove. The four modes of clock sync make interfacing with other modules, hardware or software simple. Whether driving a large Eurorack system or synced to a DAW, the groove always remains tight.

SyncBus Technology - The Tiptop Audio designed SyncBus enables the CR to connect to any number of other SyncBus devices with the highest possible level of synchronization. A SyncBus master directly injects its core clock and running status into every connected unit so they work seamlessly as one device. Hook up two CRs to make a 16 channel device or add a Trigger Riot (or three) to the mix for further experimentation. Plus, the connection is done behind the panel so no need to patch anything together.

Under The Hood - When state of the art chip technology, musically driven firmware, and professionally engineered hardware design all come together in one electronic device, the result is a music sequencer with unparalleled specifications. Starting with a powerful, precise sequencing engine that has superb feel for the groove, add internal functions that automatically balance performance and smooth user interface operation, and finish with outstanding low power consumption placing minimal stress on power supplies even at maximum output, Circadian Rhythms has a design focused on the requirements of the most dedicated musicians and composers. Long time pros will immediately feel a machine made for their needs, while the newcomers can instantly dive into next level programming and performance.

Notes: Introducing the BD808, part of our new series of drum modules that brings analog percussion into the modular synth world, instantly turning your system into a self-contained music machine. Its small size, minimalist design, and modern production methods have allowed us to bring the world's most famous bass drum sound generator back at a very low cost. The real thing is here again.

The BD808 is the Roland TR-808's Bass Drum circuit adapted for use in Eurorack format and tuned to sound like a machine that comes fresh off the original 80's assembly line. The adaptation to modular format has allowed us to add some special features like independent Accent levels, a high-powered gain stage, dual-input pulse-shaper, and extended decay - all without compromising the signature sound of the TR-808.

A widely used technique with TR-808 machines is to run the drum sounds through outboard amplifiers to add gain and then pass the sound through just about anything to generate additional harmonics caused by clipping and distortion. In the BD808, we have already included this high-powered output gain stage capable of producing signals up to 20Vpp, extending from the original palette of sounds and allowing you to get an assorted array of harmonized bass drums ranging from sharp attacks to crushed tones using this simple yet effective technique! On the inputs, we have also designed a dual pulse-shaper circuit so you can trigger your BD808 with Trigger/Gate signals from step sequencers, clock dividers, or any other pulse/clock sources. This saves you the need to shape the pulses sent to the module and ensuring the same stable sound at its peak power, regardless of differences in your pulse source.

All these little, but unique, features make integrating this legendary sound generator into your modular easy, unleashing the power of real analog drums and making those speaker cones shake.

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: Introducing the HATS808, part of Tiptop Audio's new series of drum modules that bring analog percussion into the modular synth world, instantly turning your system into a self-contained music machine.

The HATS808 is the TR-808's real, analog closed and open hi-hat circuits adapted for use in Eurorack modular synthesizer format and tested to sound just like it did back in the 80's. Adapting to modular foramt has allowed Tiptop Audio to add some special features for each voice, like independent accent levels, a high-powered gain stage, and a dual-input pulse-shaper. Filter Q and VC-Q knobs were added to the main band-pass filter for additional tuning and to allow you to generate crushed tones and self-oscillation at the knob's max position - all without comprimising the signature sound of the TR-808 hi-hats.

The HATS808 sizzling sound is made using six analog square wave oscillators mixed and processed by band-pass filters. This multi-oscillator design is what give the 808 hi-hat sounds their unique metallic character and akes each HATS808 sound slightlty different from one-another. The original "choke" circuitry that makes it sound so dynamic and tight is fully implemented, just like the original, but can also be disabled if needed, by disconnecting the internal connection between the two hats.

Just like the other drums in this series, the HATS808 high-powered output gain stage allows you to further harmonize the sound using distortion and clipping. On each input, there is a dual pulse-shaper circuit so you can trigger your HATS808 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: Reverse-engineered from the original machine, our BD909 is an identical recreation of the original all-analog drum circuit of the TR-909. We've added additional controls and synthesis features that turn this classic circuit into a chest-pounding analog bass drum laboratory - all tightly packed into an 8HP module. The BD909 sound differs from our BD808 in that the main sonic energy is centered in the mid to low frequency range (as opposed to the low frequency range of the BD808). This frequency range gives the needed headroom allowing your bass Lines to deeply fill up the low end while the kick drum rides on top - creating a clear and punchy mix.

The BD909 includes all the controls found in the original: Attack, Decay, Tune Decay, Accent and Level. We have gone beyond that and added controls that further increase the palette of sound this circuit is capable of. First off, we've added a tuning control knob for the oscillator and included its own CV input and attenuator that let you tune your 909 kick with your bass lines. Next, we added control knobs for the tuning attack and extending tuning decay - each one affects the other, allowing for very intuitive and interactive sound shaping - this feature opens up numerous "sweet spots", and provides the ability to center the energy peak at different parts of the sound. Finally, we offer additional punch and distortion by giving complete control over the internal waveshaper, which allows you to overload the waveform manually or with voltage control.

Beginning with the classic and pure sound of the 909 kick, these additional functions greatly expand the BD909's flexibility and let it create powerful analog bass drums that range from soft and smooth to punchy and aggressive - and everything in between.

Notes: Dual 4-way passive mult (one audio or cv signal in with multiple unbuffered outputs)

On the back of the pcb is a pair of solder points marked as "link". You can connect these (with a solder blob or small jumper wire) to turn the mult into a single 8 channel Mult instead of 2 x 4 channel.

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

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

Notes: A duophonic percussion/drum module which offers you two individual, almost identical voices. Each of them has an oscillator with selectable waveforms as well as an attack-decay envelope which simultaneously can modulate the pitch and the VCA.

A large number of sockets is available which not only are used for modulating and triggering the drums but also emit any oscillator waveform and envelopes. That is utterly useful!

The first difference between both voices are the available waveforms: voice A offers square, triangle and sine, while voice B has noise, square and sine. For atonal noisy sounds like hi hats and anything cymbal voice B is more suitable.
The wave forms are switch selectable and simultaneosuly available at individual outputs i.e. you can process the audio signals exernally. Using the module's EG CV outputs plus two external VCAs you can re-create or alter the signal flow. Envelope signals and audio sources are available!

For controlling the frequency there's a hi/lo switch alternating between bass and treble, then a tune control and a modulation attenuator which scales either the envelope or a nexternal CV. besides individual inputs (A VCO and B VCO) there's also a common CV input VCO A+B which addresses both voices simultaneosuly. A VCO is normalized to the VC CV input A VCA, analogical for channel B.

The second difference is in the envelopes. Voice A has an attack-decay envelope generator with manually adjustable times. Voice B has a decay envelope with fixes attack time but with voltage control of decay time via EG 2 input and the CV EG2 attenuator.
The envelope generators are able to modulate not only the pitch but simultaneously also the level. For that reason there's an second attenuator which altternately detemines the intensity of an external CV (see above).

Each voice has an individual audio output, although OUT B works as a mix output when no cable is plugged to OUT A.

*essentially two things have changed in the + version:
-the output levels of the MIX outputs have been increased
-the frequency of the filter for noise can now also be controlled via CV

Notes: Kamieniec is an analog signal processing module directly inspired by a range of classic phaser effect units from 1970s that helped to define entire musical genres. Most of these classic devices contained a fairly small number of phase shifting stages, but made up for that lack with tons of character! However, what was initially intended for guitars is not necessarily sufficient for synthesizers. Therefore, the intention is to preserve the classic sound as it's transported it to a new tonal space while prioritizing flexible modular usability.

Just like many of the famous OTA-based phasers of the 1970s, Kamieniec sports four tuneable stages. However, there are two additional fixed stages included so as to increase the number of notches, and ultimately offer two versions of the mixed signal (that may be used as a stereo pair) at the two outputs of the unit. While the general topology is similar to a certain very classic phaser pedal, the circuitry has been redesigned with modern components and low noise op-amps to bring down the noise floor, improve the bandwidth, and offer a wider range of tuning. The feedback control can be set extremely deep, which results in a very high resonance that is capable of self-oscillation. This produces a unique sound otherwise unreachable for typical phasers, which can vary from subtle and creamy to utterly brutal and grinding. On top of that we've included switchable feedback paths, individual stage group outputs, CV inputs, built-in LFO, and daisy chaining ability to provide a comprehensive integration with a modular synthesizer system.

Expandability:
Unlike any other phaser module, multiple Kamieniec units can be chained together to achieve a more radical response with many notches. The general idea of chaining is to pass along the phase shifted signal to subsequent units before it is mixed with the original version in the last unit of the chain. This approach has a very different effect than plain cascading (connecting multiple phaser units in series), because a long chain of allpass sections yields a dense and uniform pattern of multiple notches, exactly like in a long phaser.

Notes: Warna is a very useful utility module that helps you to manage control voltages in the system. Crammed in just 6 hp, there are five normalled sections: two buffered mults, two inverters, and a summing mixer. Each multiple routes the input signal to separated outputs without loss in voltage. Warna is designed for unity gain - if you apply a specific voltage to any input, it remains the same on the respective outputs. Inverters are hardwired to mults and invert the polarity of the signal applied to them. Both mults are also normalled to the mixer section via inputs. Patching anything to these inputs breaks the normalization.

The top and the bottom section both are buffered 1-in-4 multiples. The input can be inverted with a switch, i.e. its polarity will be changed by 180 degrees. Four inverted copies are then available at the outputs, meaning you can use these two sections as inverter. Bi-polar LEDs display whether the signal is positive or negative: yellow = negative, red = positive. The centre section is a four-input summing stage with amplification factor 1, a so-called unity-gain mixer. The multiples are normalized to the mixer which can be deactivated by patching.

Notes: AJH Synth have had quite a few customers asking if we can make the gain jumpers on the MiniMod VCF and VCA modules accessible from the front panel, so this 2HP module aims to address this.

The Gain Switch Multi has two switches which connect to the gain jumpers on the VCA and VCF. Switch "up" is the same as having the gain jumper in place, switch "down" is the same as removing the jumper, and gives higher gain.

Using these switches gives a similar effect to the old "headphone out to external input" trick on the original Model D but with a much wider overdrive range, particularly from the VCA.

As an added bonus, AJH Synth have also included a six way passive multi.

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

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

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

Notes: The 2hp VCA is a dual, linear VCA. It uses the renowned 2164 SSM architecture, giving it extremely low distortion and high quality audio outputs. With a CV input attenuator, and DC-coupled inputs this is your new go-to module for voltage controlled amplification of audio or CV.

Notes: ADSR is a four stage linear envelope with two expressive ranges. Each stage can be modified independently allowing for the creation of complex, multi-segment envelopes. Great for modulating filters, VCAs, and oscillators.

Notes: Stereo compressor in only 4HP!
The module was mainly designed as a dynamic tool for subgroups and sums, but also works well with single signals. Similar to classic DBX units, threshold, ratio and gain can be adjusted with just one knob. Further fine adjustments can be made for attack and release times. In addition to compression, the module can also be used as a limiter. Ducking effects can be created via a sidechain input.

The MSCL is equally suitable for subtle and strong compression effects. Ratio (1.25:1 to infinity), make-up gain and threshold can be adjusted with a single potentiometer. The threshold works in the opposite direction as the other parameters. In addition, there is a threshold switch that can be toggled between three value ranges (-15 dBu, -4 dBu, +5 dBu). This allows the MSCL to be used with other audio signals outside the modular system. In addition, it is possible to limit the gain control range by 3 dB or 9 dB. This makes the module behave similar to a peak limiter. The attack and release controls can be used to adjust the settling phase and the decay time of the compressor. At the output, it is possible to increase the gain by up to 35db. With the switchable sidechain channel, the MSCL can also be controlled by external signals.

Features:

Sidechain input for classic ducking sounds
Easy and intuitive design
Threshold switch lets you compress modular level signals as well as lower level sources
Limit switch limits the makeup gain on the comp knob to make compressor act more like a peak limiter

Notes: Cursus Iteritas is an oscillator that works from a dynamically generated wavetable. It gives the user spectral-like controls over three different modes based on different conceptualizations of frequency: Fourier, which uses sine waves; Daubechies, using wavelets, and Walsh mode, using the Walsh transform. Cursus Iteritas parametrizes a wide variety of sounds, but because the sounds are all based on orthogonal functions, it has a musical tone structure and can produce an extremely wide variety of harmonic sounds.

Notes: The ADE-50 provides 3 all-analogue voltage controlled amplifiers based on a modern operational transconductance amplifier design.

The VCA's are designed to provide a good balance between the performance and specification of modern 'on-chip' VCA's and the character and musicality of classic analogue designs.

The OTA core of each VCA is fully discrete - it is built from only resistors, capacitors and transistors - however, the CV conditioning, audio input and output stages are built using high-quality op-amps giving the best balance between musicality, character and performance.

The ADE-50 provides a good signal-to-noise ratio, linearity, attenuation, an output level at unity gain at 5V CV input, minimal CV 'bleed' and minimal output offset/bias.

Notes: TouellSkouarn Strakal Brulu is a handmade distortion and fuzz module. The great sound is due to the new-old-stock east-German germanium transistors.

Very characteristic for the module's sound if the feedback that is coupled to the feedback. The more fuzz, the more feedback - the Strakal Brulu 2 can get pretty nasty and it screams a lot at high fuzz settings and low input level. The fuzz amount can be voltage controlled, with an inverse attenuator. Input and output levels can also be set separately.

Notes: Digiverb is a lo-fi reverb effect unit that uses an Accutronic digital reverb "tank" module. The sound is somewhere between a virtual spring reverb and a dense multi tap delay but the effect is quite musical and interesting.

Use the Digiverb as a simple and fun way to add some extra dimensions to your patches!

Notes: Noise Random Tools comprises a collection of useful utility blocks that you could use in many of your patches - Clock, Random Pulse, Analog Noise, Sample and Hold, and Slew.

Features:

- Clock and Random pulse source with adjustable rate
- Analog pink and white noise source with very accurate spectrum
- Analog sample / track and hold with very low droop
- Analog slew with adjustable slew rate

Notes: Tetrapad is a versatile, multi-dimensional, touch-sensitive control surface for Eurorack. Each of its four pads use force sensing resistors to respond to both the vertical position of your finger and its pressure. Four push encoders and a shift function give you even more tactile control over your modular system.

Tetrapad operates in numerous modes - each of which configures the module to perform a specific control task. Through these modes, Tetrapad can emulate a bank of faders; a voltage storage device; a finger drumming surface; a chord generator; an 8-key keyboard; four independent LFOs; or an 8-switch panel. The chosen mode determines what type of signal (CV, note, trigger, gate, etc.) is sent from each of Tetrapad's eight independent outputs, while its multitude of multi-coloured LEDs keep you informed of exactly what's happening within each mode.

Tetrapad automatically remembers how you've configured each of its modes and retains these settings when powered off. By default, Tetrapad automatically saves these settings every minute, or whenever you change modes. This makes Tetrapad ideal for live performance, since you know it will always power up with your configurations intact.

Notes: Eurorack-outputs deluxe:
Besides spectacular sound engines and -shapers, usual and unconventional sources and manipulators of control voltages, every modular system also needs a choice of modules for the "daily" business. twinOUT is such a module: the perfect connection to the outer world.

This DI-box in a module offer two adjustable electronically balanced XLR-outputs. twinOut is designed for full stereophonic or dual mono use. To complete its functional range, a headphone output was added - being also suitable to transport line levels.

Like every VERMONA module, each twinOUT is hand-assembled in our electroacoustic manufactory in Germany. If you want to get the most of your modular synthesizer, you cannot pass by the twinOUT!

Notes: The Polaris is a 4-stage cascaded OTA filter designed by David Dixon. It builds on the lineage of the Dr. Octature and Atlantis filters, but with a totally revised core and resonance control. Along with dedicated LP, HP and BP outputs it features a configurable MULTI output capable of an unprecedented 27 different filter modes.

With drive turned down the Polaris is capable of buttery smooth filtering, and the cutoff control range has been fine-tuned for playability. With the drive dialled up and the new asymmetric multi distortion circuit engaged it creates a more aggressive sound. Not content to be just a filter, the Polaris's AP phaser mode combined with frequency modulation can be used to achieve a phaser effect.

With so much versatility in a modest size, the Polaris is an ideal filter for a starter system and an excellent addition to the tonal palette of a larger modular.

This has two LFOs, each with variable waveshape from Saw to Triangle to Ramp waveforms, or variable Pulse width on the Square wave output. LFO 1 has the addition of a low range and a Sync input. The nominal maximum frequency of the LFOs when in Triangle shape is 20Hz, but under certain combinations of settings they will go much higher, well into audio range.

Also included is a DC coupled VCA, the input of the VCA is normalised to the output of LFO 2, so a 0 to +5V input to the VCA CV input gives control of the LFO waveform amplitude. It can also be used as a stand alone VCA.

This module is very useful for controllers such as the Waldorf KB37 where the modulation wheel gives out 0 to +5V, this can be routed to the VCA CV module so the level of the modulation waveform can be easily controlled. This makes it very easy to add VCO vibrato or filter 'wah' with control of modulation amount from the modulation wheel or other controller.

Notes: The updated Chronoblob offers versatile, creatively interesting delay. Four modes offer a choice of stereo settings or mono with patchable feedback send and return. Tape-style modulation allows for fun pitch bend effects.

Supplier's Notes:
Chronoblob2 is a digital delay module!

Just like his little brother, Chronoblob2 can sync to a clock signal. Patch one into the SYNC input and choose a multiplier or divider for rhythmic delays. Or leave SYNC unpatched for access to continuously variable delay times!

Chronoblob2 offers four different delay modes! Dual delay mode provides two separate delays with shared controls. Ping-pong mode extends this intermingling even further by placing each delay in the feedback loop of the other.

Single delay is the classic Chronoblob mode with feedback SEND and RETURN. Patch in a lowpass filter for smooth, shadowy echoes, or get weird with a wavefolder or any other effect! Cascade delay mode expands on this archetype by also placing the second delay inside the feedback loop of the main delay, creating a wild multiplying echo effect.

Chronoblob2 provides control voltage inputs for TIME, FEEDBACK, and DRY/WET, and bipolar attenuators for each so you can dial in just the right amount of control.

In Dual and Ping-pong delay modes, although both delay times are controlled by the main TIME knob, you can voltage-control each independently with the two TIME CV inputs. The right TIME CV is normalled to the left one so you can easily control both with the same signal. Additionally, the left TIME CV is normalled to five volts, allowing you to use the attenuators as offsets from the position of the main TIME knob.

Also in these 'pink' modes, the right audio input is normalled to the left input, and the right audio output is normally mixed into the left output (patching into the right jack breaks this connection).

Like the original Chronoblob, you can select the style of time modulation with the slide switch. Choose tape mode for sweeping pitchbend effects or fade mode for smoother, cleaner changes.

Chronoblob2 offers an INFINITE LOOP button and gate input to shut off the delay inputs and lock the feedback at 100%.

Notes: Noise's 'simple' take on delay is anything but simple. Three-tap stereo design with wave folding, DJ-style filtering and extensive CV control. Versatile and characterful.

Supplier's Notes:
Delay. Fold. Pitch shift. Doom. Repeat repeat.

Yester Versio is the long-awaited answer to the request for a simple delay on the Versio platform. Yester Versio is a three-tap delay designed to be straightforward and easy to control. It's perfect to help glue together almost any patch, with just enough character to stand out if that's what you want.

Yester Versio comes with controls over panning, delay feedback, and delay time, but Noise Engineering didn't stop there. The Time control interacts with the Even/Triplet/Dotted switch, allowing for flexible delay syncing. These also work with the Tap button and jack input, making it easy to sync Yester to the rest of your patch and create interesting rhythms.

Use the DJ-style filter to shape your delays. Add flavor with Chorus, a bipolar control that adds a bit of clean pitch shifting or LFO-modulated effects. Turn up Fold for some gentle saturation, then gritty wavefolding, and at the top of the knob, to add in chaotic suboctaves for a bit of doom.

And of course, because it is a Versio, almost everything can be CV controlled.

Yester Versio is the delay you will keep coming back to...back to...back to...

YV is part of Noise Engineering's Versio stereo DSP platform. A simple USB connection will allow you to update to a variety of effects firmwares. Open-source support is available through libDaisy, which allows you to write your own firmware!

Notes: Get Amped

Amps comprises two precision linear VCAs that have been carefully designed to offer a wealth of flexibility and additional functionality. The front panel controls and signal normals allow these two VCAs to also be configured to function as: line level boosters, crossfaders, ring modulators, mixers, and much more. They can also be chained together by way of an included cable to form larger, more complex systems.

Amps features cascaded CV inputs and cascaded mix outputs allowing it to be used in a number of versatile configurations. A boost switch enables you to amplify each VCA's input by either +6dB or +20dB i ideal for boosting low amplitude signals or pleasingly overdriving audio. The addition of a phase inversion switch for the second channel allows Amps to function as a ring modulator. The CV normalization, which can also be inverted and offset, also allows for VC-Crossfader functionality.

Features

Manual LEVEL slider per VCA i convenient when using the module as a mixer, or for biasing the signal for CV (such as when modulating the VCA with a bipolar LFO).
Dedicated CV attenuators with dual color LEDs for monitoring bipolar CV signals.
Linear response curve.
Input and CV normalling of VCA A to VCA B to allow a single source to feed and/or control both VCAs.
Output normalling of VCA A to VCA B to allow both VCAs to feed a single output.
Each VCA has a boost switch that can increase the output level by either +6dB or +20dB.
Phase Invert switch on VCA B allows for ring modulation capabilities.
CV Invert switch on both VCAs allows for crossfading one signal into another.
4-pin link connectors on the rear panel allow for multiple AMPS modules to be chained together to create a 4-channel mixer; 6-channel mixer; etc.

Notes: Shapes is a wide ranging and fully analogue oscillator which can perform duties as both auxilliary VCO* as well as VC-LFO. Shapes can be configured to cycle continuously, or to provide one-shot shaped outputs. When set to one-shot mode, Shapes may be used as an ersatz envelope generator.

Using the Time knob, Shapes can cycle from as low as 8 seconds (whale song) to as high as 19500Hz (bat beeps).

Shapes has 3 simultaneous outputs:

sawtooth (+/-5V, 10Vpp)
ramp (+/-5V, 10Vpp)
triangle (+/-5V, 10Vpp)
Additional waveforms may be derived courtesy of the Shape knob. Anticlockwise from 0 achieves progressively logarithmic sawtooths and ramps, whereas clockwise from 0 achieves progressively exponential sawtooths and ramps. The effect of the Shape knob on the triangle waveform is asymmetric, anticlockwise from 0 achieves progressively logarithmic leading edge, whereas clockwise from 0 achieves progressively exponential falling edge. Progressively exponential triangle waveforms can be achieved using the Time CV knob (set Shape knob to 0) providing there is no jack in the Time CV input socket

Time CV input provides wide ranging control of time. It is possible to dial in something approaching 1V/oct over a limited range, although Shapes has not been designed to perform as an accurately tracking VCO. In the audio range, Shapes comes into its own when used as a 'daughter' VCO to an external 'mother' VCO by patching the 'mother' VCO into Shapes' Gate In input socket - some impressive oscillator sync style effects can be achieved.

Gate In can also be used to initiate waveforms in one-shot mode, where a pulse of any length will cause Shapes to complete one cycle.

*Shapes has not been designed to perform as an accurately tracking audio VCO.

Notes: The OpticTone is a combination of a 12dB multi-mode Vactrol Filter and a Vactrol Voltage Controlled Amplifier.

It is a completely original circuit inspired by the singular nature of Vactrols and their fluid and natural character.

The Filter section provides the three fundamental filter types: Lowpass, Bandpass and Highpass.

A Resonance knob with voltage control input is available for improved modulation flexibility. The feedback knob interacts with the Resonance path, tempering it from creamy resonance to wacky self-oscillation.

Filter and VCA run in parallel, both are controlled by the Freq/Amp knob and it's associated voltage-control input. The combination of both signals can be crossfaded with a dedicated knob.

The Freq/Amp is also controlled with direct touch control on the panel via the 3 lines below the knob.

The filter frequency control can be inverted by the Inv Freq switch, providing the possibility to change the filter direction. This feature allows the filter to "close" when the VCA is "opening" or the other way around.

The Ping input allows to generate the well known vactrol filter percussive sounds if a gate or trigger signal is provided. The Ping frequency if controlled by the Freq/Amp knob, ranging from low kicks drums to high pitch bongos.

There is also a Drive knob to take care of your saturation needs. The Overdrive range is wide, from soft textural clipping to heavy distortion.

All voltage controlled inputs have an attenuator-inverter knob.

Features:

Vatrol based 12dB multi-mode Voltage Controlled Filter: Lowpass, Bandpass and Highpass.
Vactrol Based Voltage Controlled Amplifier.
Crossfade between VCF and VCA section.
Voltage controlled Resonance.
Ping Input for percussive sounds generation.

Notes: Designed with versatility in mind, MapVolt is a dual-channel Universal Voltage Processor built for flexibility in handling audio and CV signals.

With only 6hp, Mapvolt is a multipurpose tool for voltage-controlled scaling, inverting, offsetting, subtracting, and mixing functions.

Each channel of MapVolt can operate in either Polarizer or Attenuator mode, allowing manual control via knobs or CV signals. In Polarizer mode, it functions as a Voltage Controlled Attenuator-Inverter, granting control over signal level and polarity. Additionally, it can be used as a Four-Quadrant Multiplier or Ring Modulator for audio signals, with the processor input serving as the carrier signal and the polarizer's CV input acting as the modulator.

In Attenuator mode, MapVolt operates as a VCA, providing control over signal levels. Its VCA CV input range of +5/-5 makes it well-suited for amplitude modulation (AM) with other +/-5V waveforms.

MapVolt is equipped with dedicated Voltage Offset knobs for each channel, which can be controlled via CV. If no input is patched into the Processor input channel, the Voltage Offset knobs can be used as Offset Generators.

With its dedicated mixing stage, MapVolt enables the combination of both channels into a shared output. Furthermore, if one of the processor channels is inverted, it allows for the subtraction of one signal from the other.

Notes: A Juno-inspired oscillator module? We're flattered, but credit has to go to Roland for this one. Based on the Juno-106's digitally-controlled analogue oscillators, the Castor & Pollux modernises the 80s design with a built-in LFO and hard sync.

Supplier's Notes:
Twins that dance in and out of phase, never completely together but never fully apart, bound to each other in the infinite universe.

Castor & Pollux is a dual oscillator that echoes back to the legendary Roland Juno but shines with its own unique, massive voice. It contains two digitally-controlled analogue oscillators implemented using a faithfully modernized version of the original Juno 106 design. It builds on the classic '80s sounds of its inspiration by using the second oscillator and internal LFO to layer in thick detuned sounds and harmonically complex hard synced waveforms.

Castor & Pollux II brings a redesigned interface and moves individual waveform outputs to an included expansion. Both versions have the same features and use the same firmware.

Notes: The 2CVADD-HQ is a dual precision adder especially for adding 1V/octave (pitch-controlling) CVs. This makes it possible e.g. to transpose a sequence. Compared to general purpose CV mixers (like POLAMIX), this module does the summing of the CVs very precise (within a few millivolts), so the desired pitch is not affected.

The module offers three CV inputs for each of the both units; the first unit has an additional fourth input where the CV is subtracted - meaning "transposition downwards".

If you would like to have transposition buttons to shift by one or two octaves (or a free offset), take a look at the CVADDER-HQ module.

Notes: The classic ADSR envelope with CV control for all parameters

The ADSR module offers the classic four-stage envelope (Attack, Decay, Sustain, Release) that is not only loopable (patch the end output into gate input) but also accepts CV control over each of the stages! For the time values (A, D, R) the value set by the knob can be increased to five times the duration by the corresponding CV value. For the Sustain value the knob and CV value are simply added.

Notes: The CVADDER-HQ is a precision adder especially for adding 1V/octave (pitch-controlling) CVs. This makes it possible e.g. to transpose a sequence. Compared to general purpose CV mixers (like POLAMIX), this module does the summing of the CVs very precise (within a few millivolts), so the desired pitch is not affected.

The module offers four CV inputs where three of them are summed, and the CV at the fourth input is subtracted - meaning "transposition downwards".

This module also allows transposing the incoming CV by one or two octaves or a variable offset by buttons.

A separate output provides the voltage of the internal transposition (+1, +2 octaves / free).

If the transposition buttons are not necessary and you prefer to have a dual precision adder, take a look at the 2CVADD-HQ module.

Notes: The CVSHIFTER module is the AE version of the well-known analogue shift register modules that are around in the modular world since a long time. It works like this: The CV input is sampled with each trigger input signal and this CV is sent to the CV 1 output; at the same time, all CV outputs 1-4 are shifted by one.

Compared to the "classic" circuits, this module is digital based and therefore doesn't suffer from drift as some analogue ASRs and S&Hs do. The result is, that you can e.g. control the pitch of up to four oscillators which is a first step into polyphony.

The CVSHIFTER module offers three modes:

Classic: Each trigger shifts the CV outs by one position, the new CV goes to output CV 1
Cycle: Each trigger sends the CV to the next output channel, restarting at out 1; additionally a gate signal at the according output.
Random: The CVs are sent in random order to one of the four outputs, plus a gate at the according output.

Notes: The Erica Synths Envelope Generator 2 is a re-triggerable, looping envelope generator with some unconventional features that are very useful for experimental setups. What sets the Black EG2 apart from other envelope generators is its optional GATE LENGTH setting, which allows for generating full ADSR envelopes even if a short trigger is used at the input. Likewise, in LOOP mode, the module outputs a full ADSR envelope instead of a classical AD envelope. The gate length is both manual and CV controlled, which allows for using this envelope generator in compact modular setups controlled by trigger sequencers only.

LOOP/SINGLE

Select between SINGLE SHOT or LOOP modes. When the internal gate is o , the rise and fall times are set via the A and R knobs. When the internal gate is on, all knobs have an e ect on the envelope shape.

The LED gives visual feedback on the envelope state.
GATE ON
Engage the internal gate and you have a full ADSR envelope in loop mode and with a trigger applied to the trigger input in single mode.

G. LENGTH

Set the internal gate length manually

LENGTH CV

This is the internal gate length CV input.

The CV is added to the gate length potentiometer setting

GATE

This is the GATE input

A / D / S / R

These knobs adjust envelope stage times and sustain level

TRIGGER

This is the TRIGGER input. You can retrigger the envelope and start the attack stage again, even if the gate is still high (see Figure 1).

If you wish to use the envelope generator with an internal gate, patch the incoming trigger signal here. The internal gate is linked to the trigger input, not the gate input.

EG OUT

This is the envelope generator output.

Inspired by the legendary Moog CP3 mixer, the 713 tweaks the old-school discrete circuits into three stereo inputs and one mono channel, summing to stereo with adjustable feedback and clipping to add character.

Supplier's Notes:
ADDAC713 is the stereo version of ADDAC System's 703 Discrete Mixer.

Inspired by Moog's CP3 mixer, this is a fully discrete analogue mixer and it's not, by any means, your standard breakfast mixer, although it can behave like one.

This is a wolf in sheep's clothing. Despite its harmless looks there's a dark snarly soul behind that panel that wants to take your sounds into a realm of gritty gnarly growls.

This new version was initially thought of as a percussion mixer, with mono inputs and panning, to allow placing percussive voices in the stereo field, while keeping channel 4 in mono for low end sources like a kick drum or Bass. In the development process ADDAC System slightly changed this initial idea, adding stereo inputs for the first 3 channels, but still kept the 4th channel in mono.

All four [GAIN] controls go to extreme levels, the first 3channels also feature [PAN] controls. Feedback is used to overdrive the whole mix. As the control is turned clockwise the sound will be clipped harder until it goes completely off, this happens as feedback is increased the audio bias reference also moves up, at extreme levels it offsets the whole signal upwards until it completely goes above the top rail clipping the whole signal hence the resulting gate effect.

The [MASTER OUTPUT] sets the overall output gain of the mixer, the two leds monitor the audio output signal. The Soft clipping switch engages an anti-click circuit which adds a low pass before the output, the switch allows 3 states: Soft low pass / Off / Hard low pass.

Features:

Three channels with stereo inputs, gain and pan knob
One channel with mono input and gainknob
Feedback/gate knob
Master output volume knob
Soft clipping switch
Two Led Monitors for Left and Right channels
