Synth modules

Notes: The Triple Cap Chaos(C^3 Chaos) is a 2hp analog, chaos based, noise oscillator, pseudo ring modulator/harmonics generator, and audio mangler Eurorack module available as a DIY Eurorack kit, PCB and Panel, or built.

It is a unique module, like the Diode Chaos, because it has never existed as a musical instrument until now. There is also no other module to my knowledge that can do exactly what the Triple Cap can do. The circuit(with several modifications) is based on the paper "Simple Autonomous Chaotic Circuits" by J.C. Sprott and Jessica R. Piper. As opposed to the Diode Chaos that generates control voltage this module focuses on the audio rate.

The "Emanate" potentiometer controls the coarser overall spectrum of the chaos, from lots of activity counter clock wise up to less chaos and more of a steady oscillation. The "Width, CV ATT" potentiometer can be thought of as more of a fine control for the chaos/oscillator. When something is inserted into the "CV" in the voltage normalization from the width knob is broken and the potentiometer now acts as an attenuator for the incoming cv. The Triple Cap is not a traditional volt per octave exponential VCO, and has a sort of narrow frequency range to exploit the chaotic behavior.

It expects a +5v to -5v max signal in to modulate the chaos. The "IN" jack is an A.C. coupled input for audio in, although cv and audio can work for both the "CV" in jack and "IN." The "IN" will interfere and interact with the onboard chaotic oscillator depending on the frequency of the input, which may take some experimentation. It can create ring mod ish sounds, to added harmonics, to almost bit crushed sounds depending on the "X" or "Y" output. The "X" output is a more windy noisy sinusoidal based output and the "Y" output is more squared off and aggressive, harsher sounding output.

Some quirks about the Triple Cap: The "X" output can offset negatively or positively a little bit depending on the pot settings, but both outputs tend to stay around 10vpp. With the "Emanate" and "Width" pots all the way up the typical frequency will be around 150hz although some will reach 200hz at this setting. With the "Emanate" pot full counter clock wise "Width" pot full clock wise the frequency will be around 250hz. It is possible to send signals into the triple cap that can bring it out of the desired range causing the oscillation to cut out.

The Triple Cap has a double sided panel. meaning one side has the classic graphics and the other is Soulless with less graphics.

Notes: Additive synthesis oscillator based on the concept of building up harmonics from sine waves. A complex idea nicely executed for ease of use.

Suppliers notes:
Odessa implements the principle of additive synthesis controlled by a set of carefully tailored macro parameters to harness thousands of sinusoidal partials that altogether form the resulting sound.

The interface is kept simple and accessible, so you can easily build rich and full, great sounding timbres of very complex spectra, that can be either harmonic or inharmonic. Even though inharmonic spectra yield non-periodic waveforms, all partials are frequency related to the common fundamental controlled by a V/oct input. The series of harmonics can be squeezed or spread apart, tilt, and pruned by a comb-like frequency response, resulting in a variety of unearthy sounds. Animating the comb response yields radical effects similar to flanging and phasing. Additional, often sought after features are implemented: through-zero linear frequency modulation, and unison detune: up to 5 copies of the sound can be spread apart for a fat and dense cluster of voices.

There are nine parameters, each controlled by a dedicated knob, so the workflow is as smooth and immediate as possible. Furthermore, every parameter has a dedicated CV input, allowing live animation for organic audio effects. Odessa sports two main outputs for banks of harmonic partials that can be further scaled in frequency, as well as an additional output that can either spit out a square wave or a single sinusoid of the fundamental frequency. Interesting spatial effects, crazy modulation feedbacks as well as synchronisation is possible that way.

The hardware is based on a powerful FPGA chip offering massive parallel computing. The synthesized signal is devoid of aliasing through the entire audio range thanks to intrinsically bandlimited algorithm. A simplified spectral analyser helps you to keep a visual track of what is actually happening to the harmonics.

For even more control over Odessa, you can use the Leibniz subsystem (or just the Lipsk) that can be connected to a header at the back of the module.

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

Notes: An updated version of the excellent Batumi quad LFO, version II introduces performance updates plus compatibility with the new Poti II expander. Original Poti I breakout functions are now included in the Batumi II.

Supplier's Notes:
Xaoc Devices presents Batumi II - a greatly improved and enhanced new iteration of the modern day classic that is/was the original Batumi, preserving its layout and form factor. The premise remains the same: four LFO's with individual outputs for sine, assign and rectangle waves. The channels can operate independently or they can be linked - phase shifted, divided or multiplied (new mode alert) with regard to the first channel. Multiple major and minor improvements have been implemented, e.g. when synced to an external clock source, each channel's frequency slider selects a clock division for that channel's outputs.

Xaoc Devices have managed to incorporate the features of the original expander into Batumi II (sync mode switching and assign waveform selection) without changing the size of the module which opened up new possibilities for the new optional expander. The Poti II expander for Batumi II adds multi destination inputs for sine wavefolding, assign output waveform selection or rectangle pulse modulation with the destination set for each channel independently. Poti II also features frequency input attenuation as well as sine and assign output attenuation. All adjustments may be performed separately for each individual channel or for all channels simultaneously.

The Batumi II software has been rewritten from scratch to ensure best performance. The hardware has also been updated to allow for V/oct tracking and stable operation up to audio rates (more powerful CPU, precise, wideband converters, antialiased waveforms).

-4 LFO's
- redesigned from scratch - both the hardware and software
- new waveforms for the assign output (including random)
- new frequency multiplication mode
- all features of the Poti expander incorporated into the main module
- very wide frequency range well into audio rate
- 1V/oct tracking = so can be used as 4 VCO's
- in the Phase/Divide/Mult modes the random waves at the ASGN output follow the values available in the master/A channel
- 10HP
- +90/-50mA

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

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

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

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

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

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

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

Notes: Inspirational west coast sounds from one of the masters. Additive oscillator with eight harmonics, direct outputs and powerful CV control to scan, tilt and mix the waveforms.

Supplier's Notes:
For the first time in Eurorack, this oscillator module provides outputs for the first 8 harmonics as sine waves. Also included are triangle, saw, square waves.

A voltage controlled mixer with various methods of address allows the user to scan, tilt and mix the harmonics from both panel and external voltage control. It is built on a discrete, all analog triangle core with an old school discrete transistor exponential converter. It has inputs for linear and exponential FM, the exponential with a reversing attenuator. Of course there's a 1 volt/octave trimmed CV input as well.

HP : 32

Notes: The Dual LFO Module from Tobinski combines two low-frequency oscillators, each based on Electric Druid technology: the TapLFO3C and the LFO10. This module provides a wealth of modulation possibilities, with flexible synchronization, waveform shaping, and dynamic CV control to suit any Eurorack setup.

The TapLFO3C (left side of the module), syncs to an incoming pulse, allowing precise alignment with external clocks or rhythmic triggers. Its built-in frequency multiplier/divider further extends its range, enabling intricate timing patterns. The output can also be set to +-5v bipolar or 0v to 10v unipolar.

The LFO10-based LFO, on the other hand, resets to an incoming pulse, ensuring repeatable, synchronized modulation. The output can also be set to sample and hold mode allowing the LFO waveform to act as the signal to be sampled and the reset pulse to act as the sample trigger.

Each LFO features 16 selectable waveforms split into two banks of eight, accessible via manual switches.

Power consumption: 40mA at +12V and 45mA at -12V and 11mA at +5V

Notes: Clock generation meets waveform manipulation in this analogue harmonic oscillator. Combine with the Tobinski sequencer and/or interpolating scanner modules for the best creative results.

Supplier's Notes:
The Harmonic Timing Generator is a versatile Eurorack module that combines advanced clock generation with harmonic waveform manipulation. Combined with the Tobinski Sequencer, the module is a great tool for rhythmic and sonic creativity in the modular system.

As a reference clock generator, the Harmonic Timing Generator produces a base frequency with analogue multipliers (x1 to x8) to generate complex timing signals. Three selectors provide manual or voltage-controlled frequency switching, offering flexibility for intricate sequencing patterns. An LFO mode enables slower clocking rates, ideal for driving sequencers or generating modulation sources.

When used with the Interpolating Scanner, the sawtooth outputs of the Harmonic Timing Generator are transformed into sine waves. This allows the module to function as a harmonic oscillator at audio rates or as a versatile modulation source in LFO mode. Its dual functionality ensures that it can adapt to a wide range of patching needs, from rhythm generation to rich harmonic exploration.

The Harmonic Timing Generator is a versatile and creative tool, offering rhythmic and harmonic possibilities that complement any modular synthesizer setup. Its integration with other Tobinski modules ensures a cohesive and expansive sonic palette.

Notes: Vortex 6 us a polyphonic 6-voice wavetable oscillator inspired by the hardware design and sound of the PPG Wave 2.2, and it is the only oscillator of this type that uses true 8-bit vintage audio converters from the '80s. Dozens of wavetables are provided internally, and user tables can be loaded via an SD card. VORTEX6 has built-in vibrato, glide, and six wavetable-scrolling envelopes, all with CV. The ART-in jack and a built-in voice manager take care of incoming notes and distribute them to audio, gate, and velocity outsieither through per-voice 3.5mm jacks or the Polytip jacks. Together with OCTOPUS, one or more OCTOSTAGES, OCTOPASS, and OCTOGAIN, along with a few Polytip patch cables, it forms the world's first complete six-voice polyphonic modular synth. Alternatively, VORTEX6 can be patched to discrete mono modules or use its voice mix-out for paraphonic soundscapes with up to 12 oscillators in detune mode.

Size: 20HP - Depth: 40mm

Power: +12V 190mA / -12V 50mA

Notes: A classic all analogue saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analog polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. TipTop consider the ATX1 the best sounding analogue VCO they have ever created.

Size: 8HP - Depth: 40mm / 1.5"

Power: +12V 105mA / -12V 33mA

Notes: Dual tidal modulator with max, min & mix outs

FranKinksTides is a 18hp dual Tides (based on the Swirls pcb layout) with the max/min circuit from Kinks and some switches for sync, quadrature, pll and fm operation . It can be a double/complex oscillator, a dual function generator or any combination of oscillator, Lfo and Envelope generator with lots of cv control plus some interesting cross-modulation and sync features.

Some improvements in version 1.2:

-Mix output is now buffered, no signal bleeding on single outs.
-Mix pot controls also the balance of the signals sent to the max/min circuit.
-Uni/bi switch now also determines the signal sent to FM1.
-Clock/sync switch has now a center OFF position, no need of plugging a dummy cable in the Clock1 when using Sheeps firmware to avoid ultra fast sound bank changes.
small improvements for DIY:
-Bigger font size on the pcb.
-Parts renumbered for easy DIY.

Notes: FM synthesis for the AE!

The FMOS is a new digital oscillator that brings FM synthesis to the AE modular! It offers the basic FM synthesis with one oscillator and one modulator, running both with sine waves or triangle waves. The modulation depth and frequency ratio of the modulator can be set with a knob and additionally by CV control. If you want pure sine waves, this is for you too - simply set the modulation level to 0.

The module is based on a simple 8-bit microcontroller and an adapted design of Jan Ostman.

Notes: The Mankato Filter is a four-pole lowpass filter with positive and negative outputs at every pole, giving you slopes of 6 dB/oct, 12 dB/oct, 18 dB/oct, and 24 dB/oct simultaneously. The negative slope outputs allow you to use the Mankato as a quadrature sine oscillator with 8 available phases. The Mankato will self-resonate from subaudio to superaudio, and responds to one volt per octave through its unattenuated control inputs. When resonating, the 6dB/oct outputs are slightly hotter than the others and can be driven to lightly saturate at full resonance. The signal inputs are DC coupled, which allows you to use the Mankato as a voltage-controlled slew limiter at very low cutoff frequencies.

Notes: T-generator takes the concept of merging modulation sources and destinations into a single module.

T-generator is a multi-parameter Thru-Zero FM VCO. Main outputs are a pure sine wave with its warm sounding harmonically rich wavefolder, a triangle and a morphable square oscillator.

Notes: The SetonixSynth SkyWave is an all-analogue voltage controlled oscillator capable of producing many different timbres and unique harmonic behaviours, thanks to an original step-based control scheme which allows the user to dial in completely different wave-shapes and levels for successive oscillator cycles.

This complex VCO uses an internal feedback loop with the clock output of the oscillator triggering a step sequencer which in turn cycles through settings at the frequency of the core oscillator, thus changing the shape and level of the waveform output on a per-cycle basis while also staying in tune and tracking pitch like a typical VCO.

Notes: The Serge GTO is a newly designed, complex multi-functional module which can be patch programmed to provide various slew and sample functions both for audio and CV signals, but also act as a (dual) oscillator or filter or bitcrusher or ... It is one of the essential Serge modules. The GTO is an offspring of the famous Serge SSG.

The Smooth section will place a positive and negative slew on input voltage transitions for lag effects, voltage controlled portamento and for low frequency filter applications. In Cycle-mode (cycle jack patched to the input), the Smooth side “will oscillate yielding a voltage controlled triangle wave LFO. A high level into the HOLD input will enable the Smooth Function to be used as a track-and-hold circuit with voltage controlled slew rate.

The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. In Cycle mode, a pulse applied to the Sample input will generate complex staircase waveforms for control voltage applications and for use as audio signals.

Each side has a temperature-compensated 1V/Oct input for use as an oscillator with a frequency range of up to 20kHz (left) and 8kHz (right). Each side tracks over 5 or 6 octaves.

The Coupler is an internal comparator which compares the output levels of the Smooth and the Stepped Generators. This output is useful for generating complex control voltages or random voltages.

Notes: *** Free software update available as a free download, along with updated documentation, at the Mob of Emus product page on the Rossum Electro-Music website***

A lot to unpack here. Six-channel multipurpose oscillator/noise source/modulation generator with quantisation, trigger generators and even more. Seriously powerful all-round digital goodness.

Supplier's Notes:
Mob of Emus is a powerful music and sound design tool that packs an enormous amount of creative power into an amazingly compact 16HP module.

Mob of Emus gives you six channels of oscillators, noise sources, cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes), sample and hold waveshapes, slow random modulators, triggers, rhythm patterns, and quantization (of both internal and external signals) in pretty much any combination (well, any combination of six channels, anyway).

In addition to being able to independently program the function of each individual channel, Mob of Emus' Hex Mode provides a macro control layer that allows you to control all of its channels simultaneously (while maintaining the relationships of each channel's independent programming).

What's more, Mob of Emus' "harmonic" control structure makes it extremely easy to combine its oscillators into rich additive timbres, to combine its LFOs into stacked harmonic low frequency modulation waves, and to create modulation sources and triggers with intricate polyrhythmic patterns.

With an external trigger input, six CV inputs that can operate in six different control modes, six independent outputs, and an assignable mix output, Mob of Emus can operate as the heart of an almost unlimited variety of patches. And its 8 real-time controls will give you immediate hands-on access to a channel's (or all six channels') key parameters, inviting (and rewarding) exploration and improvisation.

Mob of Emus features include:

Six channels that can function independently or can be further controlled by a Hex Mode macro layer that lets you control all six simultaneously. Channels can be:
Wide-range digital oscillators
Noise sources
Cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes)
Sample and hold waveshapes
Slow random modulators
Triggers
Rhythm patterns
Quantizers (of both internal and external(!) signals)
Six CV inputs that can function in six different control modes
Eight real-time controls for immediate access to key channel parameters
Six individual channel outputs and an assignable mix output
The ability to store and recall 12 user presets
And much more.

Mob of Emus is 16HP wide and 25mm deep.

Power requirements (max): 130mA +12V, 25mA -12V. Reverse polarity protected.

As of March 2021, there has been a been a small bug fix to the recent software update for Mob of Emus.

The update fixes a bug where holding the Channel Selector Buttons for a short time to select a single channel and deselect any others was not working correctly.

The update fixes a bug where some Hex Mode parameters were not ignored when Hex Mode was set to off.

The update introduces a feature allowing users to double-click and hold the Hex button to reset all Hex Mode parameters and set Hex Mode to on.

Notes: Welcome to the Rosci soundscape. Rosci is a digital VCO that generates random waveforms to create unique, rich, and full sounds. You are able to control how complex the sound is-add harmonics and have a completely unique shape generate using the generate button/trigger. BUT, it can also be tuned to output basic waveforms (sine, square, sawtooth) if you so desire.

Tunable parameters breakdown:

COMPLEXITY: Essentially a generation of unique timbre.
ROUNDNESS: Set the basic shape of your waveform. Go from from sharp to soft sound, similar to filtering.
HARMONICS: Add up to 6 harmonies to your sound. The choir's here.
FORMANTS: Accentuate certain overtones in your sound (like a voice singing "ooo", "ahh", "eee").
DETUNE: Add a classic 'detune' with a changing phase wave for extra wide sound.

How does it work?

It is a pipeline of algorithms, which generates and modifies a waveform starting from top to bottom. Rosci works on a principle of key points: the generate button generates key point location and amplitudes to be passed down the pipeline.

Tunable parameters:

Beginning with complexity, you set the number of key points (even numbers only to create a waveform). Lowest complexity sets two points, and highest complexity sets up to 20 points. The number of key points will vary with each waveform generated. From there, the roundness sets the type of interpolation of the key points, from square to sine. Adjusting the harmonics creates copies of the waveform and adds them to the original waveform at double, triple, ... up to 6x the base frequency. Formants maintains the frequency of the wave, but squishes it so there is 'empty space' in between (this is also called pulsar synthesis). Finally, detune copies the waveform and 'detunes it' by increasing the frequency ever so slightly. And there you have it: a unique Rosci soundscape :)

Notes: Universal drum synthesizer with roots in the analogue world on a swappable oscillator platform

Basimilus Iteritas Alia is a parameterized digital drum voice with its roots in the analogue world. At its heart, the BIA is a simple six-oscillator additive and FM synthesizer with waveform, harmonic spread, and envelope controls. An adjustable noise oscillator and an extreme take on a wavefolder round out its synthesis abilities. Its straightforward controls make sound design fun and performable: create sub-shaking kicks, snares, hats, and unique drum hits with just a few tweaks.

BIA is a classic percussion module but you'll be blown away by how much more it can do. Use it for leads, basslines, or build a whole drum kit with some external CV. Plus, the envelope output means you can use the BIA for shaping and modulating other parts of your patch.

Notes: Warp is a novel synth engine that combines the best of additive and wavetable synthesis.

In the center of Warp's control panel is a colorful XY LED matrix that represents the sound space from which Warp draws its sounds. This XY sound space consists of 32x16 frequency spectra. Each of Warp's four voices can move freely and independently across the XY space. It always uses the surrounding frequency spectra to calculate a wavetable based on 512 sine waves in real time using additive synthesis. By changing the position, wicked wavetable sounds are possible, playable with four voices and eight oscillators and navigable in two directions. An intuitive integrated editor allows playful modeling of your own frequency spectra.
With Warp's SPEC effects the frequency spectrum can be filtered and deformed in realtime before a wavetable is calculated. The wavetable can then be modified with WARP effects like wavefolder, PWM bend, overdrive and redux. The resulting wavetable serves as source for two oscillators per voice, which can be detuned and also synchronized to each other. Each voice is followed by a 12/24dB/octave high pass and low pass filter.

Warp offers an integrated editor, with which you can playfully draw and modify your own frequency spectra. The XY-Sound Space is seen as a canvas on which you can draw your own frequency peaks. Several drawing algorithms are available as tools to edit single or a group of harmonics in a musically meaningful way. There is also the possibility to derive frequency spectra from audio samples from the SD card or to put whole wavetable audio files into the XY sound space. Likewise, the XY sound space can be exported to the SD card as a wavetable audio file of any length and bit depth, so Warp can also be used as an intuitive wavetable generator for other synthesizers.

Also on board are two internal ADSR envelopes and two LFOs, which can be routed to a variety of internal destinations using a modulation matrix. To keep the overview, all modulations are color-coded and are additionally visualized by pulsating LEDs in the modulation matrix view.

Navigation through the menu is as intuitive as with our QUASAR module and is simply done via a push-encoder and a back button. The display always shows which function the four surrounding aluminum encoders currently have, and colored LEDs next to the encoders provide visual assistance. Likewise, the tuning of the module is done via a detented encoder, which adjusts the pitch either in fine steps, in semitones or in octaves. An octave switch is thus already integrated.

For all its feature-richness, Warp still remains a playable and performance-oriented instrument. The large potentiometers serve as macro controls to control several parameters under the hood at once. This keeps the instrument straight forward with a manageable number of controls, but they are all very expressive.
Likewise, the module offers the ability to save and load presets and also comes with audio files and presets on board. Thus, Warp is ideally suited for both detail-oriented sound design and hands-on performance.

In the standalone version, Warp is a monophonic four-voice synth voice that can also be used as an oscillator. With an expander module, it will also be possible to play Warp four-voice polyphonic via MIDI and CV/Gate in the future.

Warp uses a novel hybrid engine that combines the best of additive and wavetable synthesis. With the integrated editor you can playfully draw your own frequency spectra like on a canvas into the colorful XY sound palette. Warp is a feature-rich powerhouse that lets you create all kinds of sounds, from glassy clean to crunchy crunch. Thanks to expressive macro tone controls, extreme morphs are possible in a single pot turn.

Notes: TRINITY is a 3 channel Digital Drum Synth Array packed into a 20hp eurorack synthesizer. Effectively, Trinity performs as 3 powerful drum voices packaged into one beastly drum module with a few tricks up its sleeve.

The name Trinity refers to the 3 drum channels and tips its hat to the core elements of any modern beat driven composition which is typically Kick, Snare and Hat. Trinity takes this simple idea and flips it on its head with 3 channels and an array of drum synth algorithms that use various types of synthesis (Analog Inspired, Additive, FM & Noise). This allows for a wide range of drum design capability that achieves and reaches far beyond the conventional kick, snare ,and hat.

Trinity's array of digital drum synth algorithms are very malleable by way of the 7 knobs and 4 mini-pots, each of which control a specific parameter and characteristic (Pitch, Sweep, Time, Shape, Grit, Decay, EQ, Clipper, Hold, Volume and Character) for each drum type. Each drum channel has its own trigger and v/oct in addition to extensive CV input options per channel.

Trinity's uniquely performable and switchable output matrix allows for the routing of each drum channel's output to the mix output, the individual drum channel output or both. This makes for easy performability, mutable output, parallel processing, or side chain source.

Lastly, Trinity's midi over USB connection allows for midi control over various parameters via one usb cable. USB midi makes integration a cinch by connecting one usb wire from Trinity to a groove-box or computer - instant integration

All in all, Trinity packs a hefty punch and weighs in at 20hp, 11 knobs, 3 drum channels, 3 triggers buttons, 4 drum synth algorithms based on 4 different types of synthesis, 24 CV inputs, 3 way output switching with 3 individual outputs, a mix output and a midi over usb connection.

Drum Synth Algorithms
BLOCK (Analog Inspired): Drum synth building blocks featuring sine and triangle core. Great for traditional electronic drum creation.
HEAP (Additive): Additive drum synth with 8 partials. Great for fun natural sounds and pitched percussive sounds (i.e. bells, chimes, steel drums, and wood blocks etc.).
NEON (FM): FM drum synth engine. Great for high quality FM drums, clangorous metallic percussion and more.
ARCADE (Noise): Quirky noise generator synth, reminiscent of classic 1980's arcade games sounds - zaps, crashes, explosions etc. Great for claps, hats, even some vinyl noise approximations, and all sorts of fun percussive and degraded noises.

Modes
Cycle Modes
The cycle modes can be enabled and disabled per channel.
'Round Robin' mode will switch between each drum synth type sequentially with each new trigger to the drum channel.
'Random' mode will generate a new random drum sound with each new trigger to the drum channel.
Stack Modes
The stack modes group the channels together allowing 2 or 3 drum channels to be triggered by the primary channel's trigger and v/oct inputs.
Stacked drums can be spread out similar to unison mode on a traditional synthesizer. Stack modes are inspired by the characteristics of chopped breaks where drums tend to overlap and fan out depending on the content of the chopped source material.

Notes: Based on a new digital hardware platform, the Spectraphon is a powerhouse spectral oscillator, capable of everything from analogue-style dual complex oscillators to FM and much more.

Supplier's Notes:
The Make Noise/Soundhack Spectraphon is a dual Spectral Oscillator coded by Tom Erbe of Soundhack. It uses real-time spectral analysis and resynthesis to create new sounds from those that already exist. It is inspired by classic electronic musical instruments of the past, including spectral processors, additive synthesis, vocoders, and resonators especially the Buchla 296 and Touche, but it takes a physical form more resembling the classic analogue dual complex oscillator in the lineage of the Buchla 259 and the Make Noise DPO.

The Spectraphon is the first module to be built by Make Noise on its new digital hardware platform. This hardware, engineered by Jeff Snyder and Tony Rolando, provides more i/o at higher resolutions, and a lower noise floor than we have ever had access to in a digital module, allowing us to unleash Tom Erbe's DSP code to a previously unattainable degree.

The Spectraphon has two nearly identical sides, A and B, which oscillate in one of two ways: Spectral Amplitude Modulation (SAM), or Spectral Array Oscillation (SAO). In SAM, instead of oscillating at all times like an analogue VCO, sound at the Spectraphon's input is used to modulate the amplitude of a set of harmonics. In SAM the Spectraphon can be sequenced and frequency modulated like any VCO. At any time the current spectrum can be used to create an Array for later use in SAO mode where the Spectraphon oscillates at all times, with the spectrum at the Odd and Even harmonic outputs being drawn from those stored Arrays.

The Slide and Focus controls are mode-dependent: in SAM, they determine how the Spectraphon responds to sound at the input for Spectral AM, while in SAO, they are used to modulate the Array.

In either mode (SAM or SAO), the Partials control works as a combined amplitude and timbre gate for the Odd and Even harmonic output and the FM Bus will create high definition internal frequency modulation from the opposing side of the Spectraphon. The two sides can also interact via the internal FM Bus, the Follow and Sync modes, and by patching them together.

Compact and skiff-friendly module

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

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

Notes: Mûmack is built from a temperature-stabilized analog source producing the three classic waveforms: triangle, saw, rectangle. This basic signal can be altered or enriched in several ways, which can be combined with each other, and associated with one VCA per mode.

Peak Compressor:
In the central position the signal is not modified. Turning the potentiometer to the right or to the left will compress the signal positively or negatively. It is this signal that will then feed Usual, Mûm and Hack. An LFO is dedicated to the compressor, controllable in speed and amplitude. A CV input with attenuator can also control the compressor.

USUAL:
The three waveforms are freely mixable, a CV input and a potentiometer can change the shape of the rectangle wave (PWM). The compressor intervening upstream, it can strongly influence the final form and the amplitude of USUAL. This produces complex analog waveforms, moving in time with the LFO or the CV input. The linear potentiometer makes it possible to mix the signal with the others, and to dose the volume of the direct output. The rotary potentiometer acts as an attenuator for the VCA input.

MÛM:
The Waveform potentiometer move the waveform of Mûm continuously from a attenuated triangle to a more pronounced triangle, then to a sinusoid and finally to a square wave. An LFO allows you to add a vibrato adjustable in speed and amplitude. The linear potentiometer makes it possible to mix the signal with the others, and to dose the volume of the direct output. The rotary potentiometer acts as an attenuator for the VCA input.

HACK:
Mûm's signal is taken up in a Wavefolder + compressor. Depending on the settings of the Peak compressor, and the three LFOs, we obtain complex, moving, organic waveforms. Again the linear potentiometer allows to mix the signal with the others, and to adjust the volume of the direct output. The rotary potentiometer acts as an attenuator for the VCA input.

ALL:
The three channel (Usual, Mûm, Hack) are mixed and brought together in a single output. The output volume is adjustable and a CV input with attenuator works like a VCA.

MIXER & VCA
The voltages produced by Mûmack, as is the case with many analog VCOs, can be high. The mixer allows them to be attenuated if necessary. Each of the three channels, and the product of the three, can be controlled by the VCA, with attenuator. The VCA is designed to add distortion at high values. The mixer is exponential for more subtle adjustments in low values.

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

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

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

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

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

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

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

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

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

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

Notes: Kermit is a 4-channel programmable supermodulator with morphing wavetable generator and internal modulation matrix. Four channels operate as LFOs, audio rate oscillators (with 1v/octave response on two channels), 1-shot envelopes, random voltage generators, or sample-and-holds, all responding to manual control, external control voltages, or synchronization to the module's master tap tempo clock. Designed for maximum patching power in small systems, Kermit carries an unmatched functionality-per-HP factor with an easily readable display that shows parameters in their real-world units.

The module has a 16-bit DAC to accurately render subtle changes of voltage at extremely low frequencies. The oscillator mode is best suited for bass frequencies, and the waveform "character" modes restrict the morph behavior or degenerate the audio to a minimum of 8 bits with limited horizontal resolution, like the Konami SCC chip used with the MSX computer. The tap tempo facility features an input jack and a manual button. The tempo is shown on the OLED display in BPM. The relevant units (hertz, seconds, volts, etc) or selected waveform of each channel are contextually shown on the display as the user programs the module.

List of operating modes per channel:

LFO (1 volt/octave)
LFO (with reset)
Tap tempo LFO
Audio oscillator
Audio oscillator (unison)
Code scan
1-shot envelope
Gated repeat envelope
Tap tempo envelope
Smooth random
Stepped random

Three parameters on each channel can be modulated: frequency, amplitude, or waveform. Both external CV input and internal cross modulation are programmable with hotkeys. For example: assign the output of Channel B to morph the waveform of Channel A by holding the Channel B button while turning the Channel A Waveform knob. All channels have manual control of frequency (coarse and fine), phase, wave bank, waveform morph, and amplitude. Channels A and B have full controls, C and D have single knob controls with deep parameters accessible by hotkey combinations. Still deeper functions are accessible through the Mark III menu system.

Kermit has a microSD card slot for loading custom waveforms, like its big brother Piston Honda. The SD card accepts one .WAV file in WaveEdit format (free software editor) containing 64 waveforms, also compatible with several other Eurorack modules. When loaded into Kermit, the waveforms are organized into 8 banks of 8 waveforms each. Each oscillator can select any of the 8 banks, and the 8 constituent waves can be smoothly morphed from one to another.

The Mark III morphing preset manager is in full effect on Kermit. The discrete preset mode quickly and reliably recalls all parameters in response to triggers or CV, accessing the true power of the module as detailed, carefully programmed settings are effortlessly loaded and changed. The morphing mode causes delightfully unexpected variations of the basis preset.

Insert a master clock signal and you're ready to go. Kermit is a reliable provider of endless rhythmically coherent modulation voltages and a reasonably competent "voice module" providing most common synthesis functions on each channel with an internal modulation matrix.

Notes: A unique analogue percussion module, based on principles from the legendary 909 twisted into new sonic territory. Capable of everything from classic kicks and snares to more experimental hits and complex VCO effects.

Supplier's Notes:
A machine is born

The Machine began as a quest to create a rich-sounding eurorack snare drum synthesis module to complement the existing Mutant Drums. The project quickly became too large and costly to justify the module being capable only of snare drum sounds. So, the decision was made to learn from the architecture of the TR-909's snare and kick circuits, in order to develop a module capable of generating multiple forms of analogue percussion, and various other effects.

Like the other Mutant Drums, the Machine has its roots in classic analogue percussion synthesis. Even though it can create totally alien sounds, it still has the capability to deliver those classic 909 house snares and kicks if you want them. There are no microcontrollers in the Machine. The signals and waveforms are all generated by discrete components and ICs, for a distinctly analogue sound, and user experience.

Features

Microcontroller-free analogue percussion synthesis engine
Unique Inverter Core oscillators form the MEMBRANE. Each analogue oscillator has three waveforms to select from
Capable of synthesizing everything from heavy-hitting bassdrums to classic 909-style snares and other complex timbres
Modular design gives the Machine many auxiliary purposes, great for modular sound design of many varieties, and not just percussion
The SNAPPY section is comprised of a voltage controlled noise oscillator, for modelling the noisy part of drum timbres
Both MEMBRANE and SNAPPY elements have an external input for replacing the built-in sound sources, opening up many avenues of possibility
13 control voltage and audio inputs, for a fully modular drum experience
7 audio and CV/gate outputs for maximum integration with other modules
Dedicated outputs for each WAVE and NOISE oscillator mean you can use the Machine as a complex VCO in your system, when not synthesizing percussion

The MEMBRANE's waveforms can be scanned through automatically by the wavescanner's voltage controlled clock generator, or an external clock or VCO can be used
SCAN FREQ CV forms a unique form of timbre control, making the Machine act like a complex oscillator at its WAVES output
The ENABLE input allows you to gate the wavescanner on and off with a CV or gate signal

Notes: Building on the familiar dual VCO core arrangement of Carrier and Modulator, Mindphaser is a complex oscillator which departs from this bit of ancestral DNA with a modern toolkit focused on searing, phase-modulated leads, percussive basslines and other-worldly effects!

A diverse palette of intermodulation and harmonic experimentation is offered through the Modulation Bus, its unique Waveshaper and the dedicated Thru-zero Phase Modulation Bus. An intuitive interface provides colour-coded visual feedback and responsive indication while performing in dimly-lit environments.

Two precision analogue oscillator cores

Precision, wide-range V/oct ramp cores, each ranging from deep subsonic to supersonic frequencies (ramp cores, and not triangular, deliver the ideal waveforms for analogue phase accumulation in the TZ-PM Bus)
Each core generates fundamental waveshapes which interact and mangle one-another through the complex Modulation Bus and TZ-PM bus
Simultaneous waveform outputs for each base shape
Dedicated button to toggle between RAMP or SAW for each core, inverting the phase of the ramp output
V/oct, linear FM and exponential FM inputs which are all independent of the TZ-PM functionality. The Carrier's FM occurs inside the core itself, separate from the TZ-PM bus.
DC-coupled linear FM

Carrier

The heartbeat of Mindphaser, focused on audio-rate generation. Drives the WAVESHAPER and TZ-PM bus. This core's frequency range spans the audible spectrum.

- An external hard SYNC IN forcibly resets the core, useful for punchy sequences, percussive basslines and drum synthesis -- or to sync to another VCO.

- Coarse and fine controls conveniently span the audible spectrum. Ranges further with external CV.

Modulator

An extremely wide range oscillator, spanning from deep LFO frequencies all the way up to supersonic sound! Four base waveforms and diverse internal routing options form a versatile palette of modulations for the CARRIER to feed on.

- Activating hard SYNC on the Modulator locks its core to the Carrier's heartbeat. The effect can be dramatic. Try this while phase modulating!

- Octave RANGE switch lets you quickly flick up and down between octaves. All the way beyond audio-rate and LFO speed octaves. Perfect for experimenting with different PM sidebands and taming the wide frequency range of the Modulator.

- Manual PW (Pulse Width) control and dedicated CV input for PWM.

Waveshaper

This isn't a classic waveshaper! Developed anew from the ground up, this waveshaper is focused on deep harmonic experimentation and audio obliteration. Each waveshaper parameter is capable of being "turned up to 11".

FOLD up to 5 octaves above the fundamental Carrier frequency. A ceiling forms at maximum, imparting additional harmonics.

FEEDBACK the waveshaped and phase-modulated audio through a signal path internal to the waveshaper.

AMPLITUDE modulation spans thru-zero, allowing for full-range ring modulation effects with bipolar CV or audio signals.

CLIP the final stage of amplitude with the switch to introduce a last stage of harmonics before the complex signal exits through the final OUT.

Switchable inverting attenuators on each CV input, for quickly inverting the behaviour of your modulation. The indicator illuminates red to tell you the attenuator has been inverted.

Two distinct waveshaping modes

A press of the shape switch toggles Mindphaser between RAMPOID (green) and TRIANGULAR (yellow) waveshaping modes.

These modes have a remarkable effect on the behaviour of wavefolding and overall character of the final complex OUT, in addition to TZ-PM Bus character.

RAMPOID mode folds more asymmetrically, with raucous, buzzing harmonic artefacts as you sweep and introduce TZ-PM

TRIANGULAR mode folds more symmetric, splitting the complex sine wave at its peak centre of the waveform. TZ-PM character is less raucous, and more smooth.

TZ-PM Bus

Thru-zero phase modulation in the ANALOGUE realm! Unlike its digital counterpart, analogue TZ-PM has its own character we've come to expect from analogue circuitry!

A dedicated, voltage-controlled phase modulation bus completely separate from the Mod Bus
Modulator's SINE wave normalled to the PM SOURCE input
SOURCE input allows you to modulate phase with any signal you patch in
Dedicated voltage-controlled INDEX (amount)
Manual phase lets you zero in (or not!) on the base phase before introducing modulation
Independent of the Linear FM circuitry in the Carrier core

Mod Bus

The internal modulation powerhouse, normally fed by the Modulator core, but external signals are patchable as well.

Select from the PULSE, RAMP/SAW or SINE output of the MODULATOR, or inject your own SOURCE to the bus.

Voltage-controlled INDEX behaves like a macro control when combined with various amounts and polarities dialled in at each CV destination.

Internal sends include the Carrier's classic Linear FM, Amplitude, Feedback and TZ-PM Index, with variable amounts and polarities!

Modulator waveforms internally feeding the Mod Bus behave unipolarly, for predictable modulation of every Mod Bus destination, without external patching. By patching in one of the Modulator's bipolar waveform outputs manually (or any external signal), you can override this behaviour.

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.

Notes: The VCZIII voltage controlled oscillator modules are Feedback's latest creation and are based on the VCOs of one of the most revered analogue instruments, the famous British pin matrix synth released in 1969.

The VCZIII series VCO is a result of the collaboration of Feedback modules and CMS-LAB and is a modern re-creation of those temperamental, organic and beautiful sounding VCOs from 1969 but with enhancements and adaptations to the Eurorack needs of 21st century.

There are two type of VCOs, VCZIII A based on VCO1 with variable shape SINE & SAW waveforms, VCZIII B based on VCO2 & VCO3 with variable TRIANGLE & PULSE waveforms.

Also, each VCO comes in two versions, one with normal fine tune potentiometers and one with precision multiturn potentiometer.

THIS VERSION IS WITH BOURNS MULTITURN FINE TUNE POTENTIOMETER.

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

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

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

Notes: Erica Pico Voice is amazingly versatile sound source in just 3HP. It features 8 sound generation algorithms: Karplus Strong, Chords, Wavetable, TB303 bassline emulation, PWM, Supersaw, Wavefold and Harmonic saturation, with three adjustable parameters per algorithm and CV control over one user defined parameter. Despite the small size, Pico Voice sounds bigger than it is!

Notes: Better known for analogue modules, it turns out Erica Synths are pretty damn good at digital too. Draw your own waveforms, build wavetables, tweak in real time and get freaky. Killer VCO.

Supplier's notes:
Erica Synths Graphic VCO allows you to draw your own waveforms, arrange them in wavetables and wavetable banks, morph between two selected waves and alter the resulting wave in advanced ways (FXes) - apply FM, phase distortion, ring modulation, wavefold/wavewrap, bitcrush.

Waves, wavetables, FXes and other settings can be saved and recalled from the memory instantly. The module has two outputs - the main output and the output with configurable suboscillator.

NB! To have the module functionality up to date, we recommend you to check the Erica Synths home pageor our social media from time to timefor announcements about firmware updates for the Graphic VCO. You can update the firmware of the module via miniUSB cable. More detailed instructions of the firmware update can be found in the User Manual.

The sound is clean, modern, punchy and detailed thanks to the unit running at 96kHz - quite different to some low bit-rate wavetable oscillators on the market. Wavetable interpolation is smooth as butter and with the built-in effects you can dirty things up in many different ways. The module scores highly on the sound front. The Graphic VCO is a very capable oscillator module with excellent sound quality and a lot of features that could make it the right choice, especially if live performance is your thing. - Sound On Sound
The bottom line is that the Graphic VCO is a joy to use. It's a module that's unashamedly digital, yet unmistakably eurorack. I think Erica showed a great deal of careful judgement and restraint in the design of this module. It would have been easy to have made it bloated and cumbersome trying to cram as many features as possible into it, but they kept it fairly simple which keeps the module fun and immediate in use. It's capable of a huge tonal palette ranging from beautiful to brutal that is bound to fit in with a lot of different styles and systems. - Ask Audio
The ability to draw and then effortlessly jump between different custom digital waveforms in this way feels unique on the Eurorack stage, and allows for a wide range of tones and transitions between them. - Orb Mag
