Tags: Oscillator module

Notes: Best value Buchla module ever? An official Buchla module produced by TipTop Audio, the 258t is a dual triangle-core oscillator, with sine/sawtooth wave shapes in the top half and sine/square at the bottom. Bags of character.

Supplier's Notes:
Two independent voltage-controlled oscillators. Each has one processing input, a frequency modulation input and a 1V/oct input.

Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

Trimmers:

There are three trimmers for each oscillator on the back of the module:

1V/oct is the octave tracking trimmer and is set at the factory using high precision instruments.
SHAPE is the trimmer that set the sine wave, for the lower harmonic content of the sine wave.
VC WAVE SHAPE sets the response of the waveshaper to the incoming control voltage. Both SHAPE and VC WAVE SHAPE trimmers are used to adjust the sine wave purity.

Size: 18HP
Depth: 45mm
Power: +12V 70mA / -12V 40mA

Notes: A compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain.

The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.

Notes: Belgian analogue innovators Joranalogue serve up an ultra-versatile filter module. Multimode flexibility meets self-oscillation for added sonic versatility. A hell of a lot of filter for the money.

Supplier's notes:
Representing the cutting edge in modular analogue voltage controlled filter (VCF) design, Filter 8 offers more possibilities and higher fidelity in 12 HP than ever before.

Starting from the classic OTA-style 4-pole cascaded lowpass (LP) topology, Filter 8 features separate LP outputs, each with their own character. Additional filter responses are achieved by pole mixing: 1-pole highpass, a special band boost and notch response, phase shifter and 4-pole bandpass. All outputs are available simultaneously.

Key to Filter 8's performance is the innovative resonant feedback circuit. By increasing the resonance, all outputs will resonate at the filter frequency, without any low frequency response loss. At higher resonance levels, self-oscillation is achieved, turning the module into an excellent 8-phase sine wave voltage controlled oscillator (VCO) with temperature and switchable gain compensation, low distortion, constant amplitude and accurate frequency tracking over at least 5 octaves. At sub-audio frequencies, Filter 8 can function as an 8-output voltage controlled slew modifier or 8-phase low frequency oscillator (LFO).

Simultaneous exponential and linear frequency modulation is possible, for classic FM tones or chaotic modulation. A hold feature is also provided, 'freezing' the output voltages manually or under gate control. This is useful for halting modulations, or as a sync-like effect at audio frequencies. The dedicated 'ping' input allows you to easily create crisp percussive sounds with different timbres.

While rooted in the legacy of classic synthesisers, Filter 8 provides a new approach to musical signal generators and modifiers: instead of simply a VCF, VCO, slew modifier or VCLFO, a single analogue module can now be any of those, and anything in between.

Notes: Polyphony is back!

Chord v2 is a plug and play solution for bringing musical polyphony to your system. It contains four oscillator voices, a multitude of waveforms, and intelligent tuning functionality. This new version features an expanded sonic palette and feature set in half the size of the original.

It features three primary modes of operation: Chord, Free Running, and Unison. These three modes allow the oscillators to be tuned as diatonic chords, run independently of each other, or be tuned to the same internal frequency for external v/oct sequencing through independent CV inputs.

The timbral possibilities of the Chord v2 bring its polyphonic tones to life. The module ships with eight banks of waveforms encompassing traditional shapes, vocal synthesis, organ emulation, and chiptune sounds. You can also load custom wavetables using the SD card slot on the front panel.

From harmonic drones to Switched On Bach, the Chord v2 is an unparalleled addition to any Eurorack modular.

Changes from v1:

- Half the size! 14HP down from 28HP
- Eight banks of waveforms
- Full polyphonic mode
- Harmonize in minor mode
- Custom wavetable compatibility
- Expanded chord types
- Improved synthesis engine

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

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

Notes: The Spherical Wavetable Navigator (SWN) is a six-channel synthesiser that makes it easy to create slowly morphing drones, polyphonic melodies, evolving sequences, and rich textures.

The SWN features six wavetable oscillators with independent pitch, level, and waveform controls. Six LFOs (Low Frequency Oscillators) can be used as modulation sources and/or envelopes, making it easy to add dynamic motion to your patch. Each channel is a full voice and can be "played" using the top row of buttons, the internal LFOs, or note-change detection on the 1V/oct jacks. The SWN ships with 12 three-dimensional (spherical) wavetables and an easy interface which allows you to record and edit custom wavetables from live audio. Open-source software for Mac, Windows, and Linux called SphereEdit can be freely downloaded and allows you computer to create, edit, and convert .wav files into Spherical wavetables to transfer into the SWN with an audio cable.

New firmware available which adds extra features, visit https://4mscompany.com/p.php?p=820&c=5 for details.

Notes: Third-party clone of the open-source Mutable Instruments Plaits oscillator/sound source. All the same functionality in a compact 8hp format with full-size knobs for the key functions.

Supplier's Notes:
Functionally identical clone of the Mutable Instruments Plaits. Beehive strikes a nice balance between size, reducing 12hp down to 8hp, and playability by offering full size knobs for the four main functions. Beehive also retains the same depth of the original module at 25mm. This module uses After Later's new aluminum knobs which have a nice non-slip texture and allow for more finger space over the standard 1900H Davies knobs.

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

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

Three Modes Packed Into 1U:

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

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

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

Notes: The Ensemble Oscillator is a unified polyphonic voice of sixteen complex oscillators combining additive, FM, phase-distortion and wavefolding synthesis techniques in new unorthodox ways. By quantizing the oscillators to scales or series of harmonics, the Ensemble Oscillator allows you to explore the sonic boundary between musical chords and rich evolving textures. Easily create a wide variety of sounds ranging from aggregates of pure sine waves to pulsar synthesis or pristine harmonic tones and lush wide chords to rich dirty drones and rumbling glitches. Custom scales can quickly be "learned" and saved using a CV keyboard or by manually entering notes with the controls.

The Ensemble Oscillator is designed by Matthias Puech and 4ms Company.

It has had glowing reviews from Surgeon and Surachai, and I am personally very excited about this module!

It has a simple interface, with 3 different synthesis algorithms allied to a number of different controls / CV inputs which have different effects, depending on which mode you choose. Simply hook up a number of modulation sources to the 4 inputs and start wiggling!

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: Highly sought-after utility tool that always sells out quickly. Full colour display gives visualisation as an oscilloscope, spectral analyser, spectograph, tuner and more. Waveform and clock generator options too.

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.

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.

All of the original features are present: a top selection of synthesis techniques, each with their key parameter directly at hand, enriched by a full set of complementary features.

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

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

Notes: Really clever noise-based oscillator from AJH. Drones, sweeps and bleeps aplenty, ranging from tamed to out-of-control filth. Also doubles up as a more conventional ring mod and distortion module.

Supplier's notes:
This 14HP wide module is a voltage controlled noise based oscillator, or noisillator for short. It generates 1/f noise and this is then sent through a feedback loop which allows the noise to be "tuned" to varying degrees depending on the settings of the frequency and resonance controls, or incoming frequency or resonance CV's. The tuned circuit can be FM modulated too, for some thunderous sweeping sounds. We have bright and dark outputs, which are pre and post filter respectively. The Bright output will always have a degree of noise present in the signal, whereas the Dark output can be tuned noise only when 4 pole resonance is selected. We also have an external Sync input, which will reset the resonant waveform, and we also have an Audio input, so that an external signal can be mixed into the resonant loop. Combinations of external waveforms to these two inputs can create some massive drone sounds, or sweeping sync sounds.

There is also an XOR ring modulator, which can be used as a module in its own right too. Lastly, we have an XOR amplifier, which is another independant circuit that can be used to add noise and distortion to any audio signal.

Notes: Creatively inspiring business from Xaoc as usual. The Erfurt is a digital phase accumulator, digital oscillator, binary counter or clock/audio frequency divider. Versatile stuff.

Supplier's Notes:
Xaoc Devices Erfurt is a digital module that may be used as an 8-output clock and audio frequency divider, a bi-directional binary counter, or a component of the Leibniz binary system, i.e. a programmable digital oscillator.

Erfurt features an 8-bit register which holds its current state: an 8-bit number representing digital values from 0 to 255. The state is available at the front panel via eight binary (5V gate) outputs and reflected by the 8 status LEDs. There are three clock inputs: one incrementing the state at each impulse, one decrementing, and one resetting the state to zero. The state may also be changed manually with two buttons.

When operating alone, the state of Erfurt changes by 1 at each impulse from the clock inputs, so that it counts from 0 to 255 in a cycle (modulo 256). This yields the signal frequency divided by 2, 4, 8, etc. up to 128, available at individual bit outputs. Depending on which clock input is used, the clock patterns correspond to the so called mathematical or musical divisions of the rhythm.

With two different clocks patched to the inputs, the counter alternately increases and decreases its state, and ultimately it counts with a rate proportional to the frequency difference between the clocks. A third clock patched to the Reset input may be used to shorten the sequence thus making the cycle incomplete for even more rhythmic diversity.

When there is a Leibniz data source connected at the back (even as simple as Lipsk), the state increases or decreases in larger steps, depending on the data present at the Leibniz bus (eg. the value programmed by the Lipsk buttons). The counter overflows quicker, and produces more complex patterns.

The state of the counter may be used as a phase input to a digital wave table. Connected to other Leibniz modules, Erfurt may play various roles, eg. it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc. Since Erfurt is based on CMOS logic (no CPU!), it can be clocked at very high frequencies (exceeding audio rate), therefore some selection switches are provided for clock pre-scaling.

Notes: Introduce some precisely controlled chaos to your patches with the Orbit 3, based on the orbit of a particle through 3D space. Audio and low-frequency modes allow it to work as an oscillator or LFO.

Supplier's Notes:
In everyday usage, 'chaos' means 'disorder, 'randomness'. In mathematics however, chaos has a very specific meaning. Chaos theory deals with systems exhibiting highly irregular behaviour, seemingly random yet completely deterministic.

Applying this to the world of modular synths opens up a whole new world of modulation opportunities, introducing a natural irregularity to otherwise purely 'mechanical' music, yet with much more control and repeatability than just simple randomness.

In chaos theory, the combination of all possible oscillations at a specific set of parameters is known as the 'attractor'. Orbit 3 incorporates a modified electronic analogue of the classic double-scroll attractor. Since it contains some (bi)stable regions in addition to chaotic ones, this type is known as a 'strange' attractor.

The voltages at each of the module's outputs can be thought to describe the orbit of a particle through 3D space around two equilibrium points. The positions of these points, as well as the distribution of the orbits and rate of movement can all be adjusted under manual or voltage control.

Not just limited to low frequency modulation use, Orbit 3 can operate in the audio frequency domain as well, yielding a variety of waveforms from its three complementary output pairs. These span a wide range, from near-sine waves to white noise. The addition of temperature compensation and calibrated pitch tracking makes for an unconventional and lively, yet also accurate audio oscillator.

And when you need a break from all that musical chaos, simply connecting any pair of outputs to the XY inputs of an oscilloscope will surely not disappoint!

Notes: The Stereo Triggered Sampler can record high quality stereo files, while simultaneously playing two different stereo files. A maximum of 600 samples can be loaded from the removable/swappable microSD card, in a variety of formats up to 96kHz/32-bit/stereo WAV. All sample parameters (1V/oct pitch, sample file selection, length, and start position) are CV controllable.

600 Samples:
A maximum of 600 samples can be loaded at once, arranged into banks of 10 samples each. Samples and banks can be re-arranged on the fly using the simple on-board Edit features. Newly recorded samples can be instantly played back and re-pitched, reversed, chopped up, etc... the result of which can even be bounced down and re-recorded to as a new sample! Sample files are limited to 4GB each, which is over 6 hours at 44k/16b/stereo.

Two Stereo Playback Channels:
Each playback channel has a knob and CV jack for Sample File selection, as well as a Start Position knob and CV jack for controlling where in the sample playback will begin. The Length knob and CV jack determine how much of the sample is played back: from tiny grains, to percussive hits, to longer loops... or just the entire file. These are powerful tools for re-arranging a sample, joining multiple samples, and creating dynamically re-sized loops within a larger sample. Combined with the Play Trigger jack and the 1V/oct jack, the STS can be two complete multi-timbral pitch-tracked stereo voices!
There's also a Reverse button and jack for backwards playback, and an End Out jack for synchronizing loops, or cascading sample playback with other events.

Looping and Sync:
Looping is easy: just hold the PLAY button down for two seconds to toggle loop or one-shot. The loop timing clock will output from the End Out jack. Or, send a clock into the Play Trig jack to sync the loop to external timing.

Stereo Recording:
Whether you patched 47 modules to create the ultimate percussive blast, or you want to capture your four hour ambient performance, recording high-quality .wav files on the STS is simple. Just hit the REC button or fire a trigger and a new stereo .wav file will be created on the SD card. Do as many takes as you need: the STS never deletes your files. Re-ordering or re-arranging samples into banks is easy, even without a computer.
You can even fill a bank with 10 different variations and immediately use them for playback.
By default the STS records at 44.1kHz/16-bit, with an option for 24-bit (a future update may increase the sample rate to 96kHz)

Easy sample loading:
Using a computer is completely optional with the STS, since samples can be recorded directly to the module and placed into the bank of your choosing. But for users with large existing sample banks, the intuitive automatic bank loading features make dragging and dropping your entire sample library a snap. You never have to rename your files again!

Notes: The Furthrrrr Generator has a main oscillator (carrier) with an extensive and fully voltage controllable wave multiplier and a modulation oscillator (modulator) that can cross-modulate the carrier. Each oscillator has hard and soft sync and also features an integrated tuner: if both LEDs are lit the VCO is at note A. Left LED is lit at note Ab and right LED at A#. Frequency potentiometers are ten-turn models and thus allow for easy tuning. Frequency range of the VCOs is 10Hz-10kHz (and much lower in modulator's LFO mode). Both VCOs feature 2 frequency CV inputs (1x with bipolar attenuator, 1x with 1V/octave), one FM input (jumper selectable between linear and exponential FM) as well as separate input for hard and soft sync. The voltage characteristic can be selected between 1V/octave and 1.2V/octave (Buchla norm).

The main oscillator (carrier) outputs the waveforms sine, saw, square and white noise. The two outputs marked with the magic eye are outputs of the "harmonic section" that generates very complex sounds by the wave multiplier and its parameters symmetry, order and Furthrrrr in the module's right-hand section. Symmetry lowers the level of even harmonics and amplifies the odd harmonics (this affects the pulse wave's width as well). Order adds saturation to the high order harmonics and resembles a low pass filter. Furthrrrr alters the level of harmonics set by the other parameters and produces very interesting, partly brute sounds with lots of harmonics by clipping and folding the wave. All three parameters can be voltage controlled. The carrier oscillator also has inputs for hard and soft sync, the sync-switch can synch directly to the modulator.

The modulation oscillator (modulator) has three wave forms with direct outputs: sine, saw and square. Using the internal modulation via the "mood section" the waveform is selected with a button; an additional staircase wave form is available here, but it can be overridden by inserting a signal into the external input socket. A switch activates the LFO mode.

The Mood section is responsible for the internal modulation of the carrier by the modulator. Switches determine the modulation destination(s) that can be activated simultaneously. These are the Furthrrrr parameter of the harmonic section, the amplitude and the frequency of the carrier oscillator. The "balanced" switch activates the ring modulation between both VCOs. intensity of modulation is controlled by the "mood index" potentiometer and the according CV input with bipolar attenuator.

Notes: The 2OSC/d module contains two 1V/octave hybrid oscillators. Each of them features:

- One frequency knob plus a range switch +2 octaves
- CV input (1V / octave)
- PWM input
- SYNC input
- Sawtooth/Square/Sub-octave output

The pulsewith knob controls either the pulsewidth of the first oscillator (with the second one having a fixed pulsewidth), or via a switch the second oscillator is also controlled by the pulsewidth knob. Both oscillators can be pulsewidth-modulated independently by their PWM inputs.

The module is designed as a hybrid digital/analogue module; the oscillator frequencies are determined digitally and are therefore quite stable and have a good tracking; the output wavefom itself is created analogue. It's a new idea/concept that I have implemented here; the design causes the waveform to get a bit gritty at higher frequencies (but not "digital noise") - it's the character of this thing!

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.

Power consumption: 120mA at +12 V and 90mA at -12 V

HP : 32

Notes: Deckard's Voice is an entry level semi-modular synth from Black Corporation for eurorack systems. Sharing the same paradigm and circuit as it's bigger brother Deckard's Dream, trimmed down for eurorack and supplemented with the flexibility available only in a modular format.

Notes: Module A-143-9 is a derivative of our planned thru-zero quadrature VCO. It is a voltage controlled sine LFO with 4 outputs. The phase shift between the outputs is 90 degrees. The sine shifted by 90 degrees is also called cosine, the sine shifted by 180 degrees is nothing but the inverted sine, and the sine by 90 degrees is nothing but the inverted cosine.

The frequency range is from some minutes to frequencies beyond audio with three ranges selected by a toggle switch:

- Switch position H: about 30 Hz ... 3.5 kHz with the manual frequency control ("Frq."), beyond 20 kHz with additional external CV
- Switch position M: about 1 Hz ... 150 Hz with the manual frequency control ("Frq.")
- Switch position L: about 0,1 Hz ... 10 Hz with the manual frequency control ("Frq."), down to several minutes with additional external CV

Two exponential frequency control inputs are available: CV1 without attenuator and CV2 with polarizer. Consequently the module can be used even as an experimental sine VCO but does not feature an exact 1V/oct CV input! The precision CV input will be left to the thru-zero quadrature VCO.

Two LEDs display the positive and negative share of the sine output.

The core of the module is a so-called quadrature circuit that generates a sine a cosine signal with very low distortion. The quality of the sine/cosine signals are much better than those generated by a waveform converter with a sawtooth or triangle signal as starting point.

The output levels are about 5 Vss (+/-2.5V) but can be adjusted internally by a trimming potentiometer (P5 "Shape").

Typical applications:

- External sine/cosine oscillator for the frequency shifter A-126
- Modulations with pure sine/cosine waveforms
- Quadrature/barberpole effects (e.g. with the voltage controlled mixer A-135)
- Experimental sine/cosine VCO (e.g. for FM sounds)

Many users suggested to add a common output level control, i.e. four VCAs with one common control (manual + CV without attenuator + CV with polarizer) for the output levels. This is why we also designed the Quad VCA module A-132-2 with the possibility of an internal default connection to the four outputs of the A-143-9 (no soldering required, short 10 pin flat cable with removable connectors on both ends).

The A-143-9 is also a meaningful addition for the Frequency Shifter module A-126. It enables frequency shifting even below 50 Hz generating e.g. these mellow beat sounds with a few Hz frequency shifting only. The following document describes how to connect the A-126 and the A-143-9: A126_A143_connection.pdf.

The thru zero version of the A-143-9 with temperature compensation is the module A-110-4.

Notes: Fusion VCO2 is a full analogue sound source with lots of distinct features.

The core of the module is highly stable AS3340-based VCO with three simultaneously available waveforms, transistor-based suboscillator and detune function - two BBD delay lines that make frequency shifter that is mixed back to the principal oscillator in order to emulate two detuned VCOs. Tube crunch - distinct tube overdrive - is added on the top of the mix. Furthermore, Audio input mixes an external audio signal with the principal oscillator which results in crazy sonic experience. Fusion VCO2 is exactly what you need, if you wish to get really low frequencies and have a sound that sets your modular system apart from mass!

" Full analogue design
" Great tracking over 8 octave range
" Detune function for thickening the sound
" -1 oct transistor based suboscillator
" Tube overdrive circuit
" External audio input
" VCO synchronization

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.

Rossum Electro-Music made a change to the behavior of the LEDS when using the utility 'Display Software Revision'

Notes: Module A-171-2 is a voltage controlled slew limiter with a lot of additional features beyond a simple slew limiter. It's mostly a licensed copy of Ken Stones VCS which is in turn based on the Serge VCS.

Typical applications:

- VC Slew Limiter / VC Portamento / VC Low Pass Gate:

Cycle switch = off, no trigger signal applied to Trig socket: Voltage controlled Slew limiter or portamento generator: the signal applied to the signal input is "slewed". The slew up and down times are controlled manually by means of the Up and Down controls, the effect of the CV Up and CV Down control voltages are controlled by the CV Up and CV Down controls, in exponential mode these controls also affect the slew shape (see symbols at the CCW and CW positions of the controls).

If an audio signal is applied an short slew rates are chosen the module works as a simple VCF/VCA combo.

- A/D Envelope Generator / Pulse Delay / Subharmonic Generator:

Cycle switch = off, trigger signal applied to Trig socket, no input signal: Simple Attack/Decay envelope Generator, the rise and fall times are controlled like the slew up/down times above, including the shape of the falling/rising slope of the envelope, the exp. CV input can be used to change both attack and decay simultaneously.

At the End output a pulse appears as the end of the envelope is reached (less than about 20mV), this can be used as a pulse delay.

If a series of triggers are applied to the VCS faster than the total rise and fall times, the module will divide the incoming signal by a whole number. In the audio range the output will be the sub-harmonic series.

- VCLFO / VCO:

Cycle switch = on, no trigger signal applied to Trig socket, no input signal: Voltage controlled LFO/VCO, the rise and fall times of the waveform are controlled like the slew up/down times above, including the shape of the falling/rising slope
the exp. CV input can be used like the CV input of a VCO or VCLFO, the response is exponential but not exactly 1V/oct.

Notes: Module A-126-2 is a fully analog frequency shifter for audio signals. A frequency shifter is an audio processing unit that shifts each frequency of the incoming audio signal by the same frequency. If the shifting frequency is e.g. 200Hz an incoming audio frequency of 1000 Hz becomes 1200 Hz, 2000Hz becomes 2200 Hz, 3000 Hz becomes 3200 Hz and so on. Pay attention that this is different from pitch shifting where all frequencies are shifted proportional (e.g. 1000>1200Hz, 2000>2400Hz, 3000>3600Hz) !
The frequency range of the internal quadrature VCO is about 8 octaves (about 20Hz ... 5kHz). If required an external quadrature VCO can be used.

The module is equipped with these controls, inputs and outputs:

Frequ. 1: first manual control of the shifting frequency (factory setting: coarse, range about 20Hz - 5 kHz)

Frequ. 2: second manual control of the shifting frequency (factory setting: fine)

by means of internal jumpers the sensitivity of Frequ.1 and 2 can be swapped (i.e. Frequ.1 = fine and Frequ.2 = coarse)

the relation between coarse and fine control is about 25:1 (corresponding to about 8 octaves to 1/3 octave)

FCV In (socket) and FCV (small control without knob): control voltage input with attenuator for the external voltage control of the shifting frequency

Mix: manual control of the up/down shift panning unit, fully CCW = down shift, fully CW = up shift, in between a mixture of down and up

Mix CV In (socket) and Mix CV (small control without knob): control voltage input with attenuator for the mixing unit for external voltage control of the up/down mixing

Audio In (socket), Level (small control without knob) and Overload (LED): audio input with attenuator, typ. audio in level = 1Vpp, the level control has to be adjusted so that the overload LED just begins to light up a bit, when the LED is fully on clipping/distortion occurs, when the LED is permanently off the input level is too low and the signal-to-noise ratio increases

Audio Out (socket): audio output of the frequency shifter

Squelch (small control without knob): controls the squelch function: fully CCW (Env.) the output VCA is controlled by the envelope signal, which is derived from the audio input signal, fully CW (open) the output VCA is permanently open (no squelch function), in between the squelch intensity can be adjusted

Quadrature VCO Outputs (sockets Sin and Cos): outputs of the internal quadrature oscillator, about 12Vpp level (+6V/-6V)

Ext. Inputs Sin and Cos (sockets): required when an external quadrature VCO (e.g. A-143-9 with a wider frequency range or A-110-4 with thru zero feature or A-110-6 with different waveforms) is used instead of the internal quadrature VCO, the levels of the external VCO should be about 10Vpp (8...10Vpp are OK) and the signals have to be symmetrical around zero Volts, the sockets are normalled to the internal quadrature VCO (i.e. the sockets are equipped with switching contacts that interrupt the internal connection as soon as a plug inserted)

VCA ext. CV (socket): used when an external control voltage (e.g. from an envelope generator) should be used to control the output VCA instead of the internal squelch unit, the socket is normalled to the output of the squelch control (i.e. the socket is equipped with a switching contact that interrupts the internal squelch connection as soon as a plug inserted). From about +8V external control voltage the VCA is fully open.

Internal terminals (pin headers, e.g. for a DIY breakout module):

envelope follower output

dome filter output 1

dome filter output 2

ring modulator 1 output

ring modulator 2 output

Up shift output

Down shift output

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

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

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

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

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

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

Notes: 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: Wow. Oscillators don't come much more special than this. Two contrasting, fully independent VCOs with waveshaping and complex cross-modulations, plus the 'Thru Zero Trinity' of FM, phase and amplitude modulation. Beautiful.

Supplier's Notes:
Thru Zero Complex Oscillator

A new complex oscillator, featuring two independent VCO's. Both voices have a unique signal path and flavour. Complex cross modulations entangle them together, opening up completely new timbral territories.

Features include the Thru Zero trinity; Frequency, Phase and Amplitude modulation.

Each oscillator also has its own Low Pass Filter, which works great to mellow the harsher tones from complex intermodulations.

Each VCO has great tracking and temperature stability, there is no distinction between a carrier and modulator.

The FM bus lets you modulate the index of each individual voice, with linear and exponential inputs for external sources. There are also inputs for Sync in, with both soft and hard sync.

VCO 1

The left VCO signal chain starts with a shape function, that let's you morph between triangle and saw. This waveform is also available as a separate output.

Next is a sinusoidal wavefolder, which changes its response dramaticaly based on shape of the waveform. The circuit is based on a modified version of a design by Barrie Gilbert from 1977, popularized by Open-Music-Labs (used with permission).

This circuit also creates the possibility of Thru Zero Phase Modulation, here the depth is controlled with the third slider. The source is normaled to VCO 2, but external modulation sources can be patched in, and the depth can also be modulated with CV.

Lastly there's a 2-pole Low Pass Filter, before going out the MAIN output. All parameters can be CV controlled, and feature handy attenuators at the inputs.

VCO 2

The first slider is a continuous waveform shaper, that morphs from sine to tri to saw.

This waveform then enters the Thru Zero Amplitude Modulation (Ringmod) section. The slider sets the depth of modulation, with the source normalized to VCO 1. The depth can be CV controlled, and an external source can be patched as well. The result is also available on a separate output, pre wavefolder/filter (VCO 2 sine).

The third slider is a wavefolder, it's based around a novel wavefolding topology, with a unique and more aggressive sound compared to the sinusoidal folder of VCO 1.

The wavefolded signal goes into a 2 pole Low Pass Filter, and out of the MAIN output.

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

Notes: 'Vintage' black panel version of Doepfer's updated frequency shifter module, offering weird and wonderful effects by shifting all frequencies by a fixed amount. Unique sound, not to be confused with pitch shifting.

Supplier's Notes:
Module A-126-2 is a fully analog frequency shifter for audio signals. A frequency shifter is an audio processing unit that shifts each frequency of the incoming audio signal by the same frequency. If the shifting frequency is e.g. 200Hz an incoming audio frequency of 1000 Hz becomes 1200 Hz, 2000Hz becomes 2200 Hz, 3000 Hz becomes 3200 Hz and so on. Pay attention that this is different from pitch shifting where all frequencies are shifted proportional (e.g. 1000>1200Hz, 2000>2400Hz, 3000>3600Hz) !
The frequency range of the internal quadrature VCO is about 8 octaves (about 20Hz ... 5kHz). If required an external quadrature VCO can be used.

The module is equipped with these controls, inputs and outputs:

Frequ. 1: first manual control of the shifting frequency (factory setting: coarse, range about 20Hz - 5 kHz)

Frequ. 2: second manual control of the shifting frequency (factory setting: fine)

by means of internal jumpers the sensitivity of Frequ.1 and 2 can be swapped (i.e. Frequ.1 = fine and Frequ.2 = coarse)

the relation between coarse and fine control is about 25:1 (corresponding to about 8 octaves to 1/3 octave)

FCV In (socket) and FCV (small control without knob): control voltage input with attenuator for the external voltage control of the shifting frequency

Mix: manual control of the up/down shift panning unit, fully CCW = down shift, fully CW = up shift, in between a mixture of down and up

Mix CV In (socket) and Mix CV (small control without knob): control voltage input with attenuator for the mixing unit for external voltage control of the up/down mixing

Audio In (socket), Level (small control without knob) and Overload (LED): audio input with attenuator, typ. audio in level = 1Vpp, the level control has to be adjusted so that the overload LED just begins to light up a bit, when the LED is fully on clipping/distortion occurs, when the LED is permanently off the input level is too low and the signal-to-noise ratio increases

Audio Out (socket): audio output of the frequency shifter

Squelch (small control without knob): controls the squelch function: fully CCW (Env.) the output VCA is controlled by the envelope signal, which is derived from the audio input signal, fully CW (open) the output VCA is permanently open (no squelch function), in between the squelch intensity can be adjusted

Quadrature VCO Outputs (sockets Sin and Cos): outputs of the internal quadrature oscillator, about 12Vpp level (+6V/-6V)

Ext. Inputs Sin and Cos (sockets): required when an external quadrature VCO (e.g. A-143-9 with a wider frequency range or A-110-4 with thru zero feature or A-110-6 with different waveforms) is used instead of the internal quadrature VCO, the levels of the external VCO should be about 10Vpp (8...10Vpp are OK) and the signals have to be symmetrical around zero Volts, the sockets are normalled to the internal quadrature VCO (i.e. the sockets are equipped with switching contacts that interrupt the internal connection as soon as a plug inserted)

VCA ext. CV (socket): used when an external control voltage (e.g. from an envelope generator) should be used to control the output VCA instead of the internal squelch unit, the socket is normalled to the output of the squelch control (i.e. the socket is equipped with a switching contact that interrupts the internal squelch connection as soon as a plug inserted). From about +8V external control voltage the VCA is fully open.

Notes: Combining the power of multi-oscillator wavetable synthesis with the percussive detail of sampled sounds, Pianophonic is a powerful hybrid synth engine featuring 8 voices of polyphony. Not limited to Piano sounds, the voice architecture of Pianophonic is extremely versatile and easy to use with the essential controls laid bare on the front panel, and the most significant CV inputs and outputs provided for full integration within eurorack patches.

Taking its inspiration from the wavetable/sampler keyboards of the 90s, Pianophonic revisits a lean and mean approach to digital sound creation but instead with 24bit 48Khz quality and fingertip control of the parameters that really matter.

With a built in SD card and an online re-synthesise utility, allowing users to create their own sound banks, the possibilities for sound exploration are limitless.

-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.

Notes: Based around the logical assumption that a decent drum pattern starts with kick, snare and hi-hat, the Trinity is a three-voice digital module designed to cover all the main elements. A lot of versatility in a nice format.

Supplier 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 (Analogue Inspired, Additive, FM & Noise) allowing for a wide array of drum design capability that achieves and reaches far beyond the conventional. 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 voice. Each drum channel has its own trigger and v/oct in addition extensive CV input options per channel.

Trinity takes its capabilities a few steps above and beyond most with the addition of its Cycle modes (Round Robin& Random) and Stack modes (2 Stacks & 3 Stacks).

Round Robin cycle mode cycles through the drum algorithm types one after another with each trigger. Random cycle mode randomizes the parameters of a channel's chosen drum algorithm type with each trigger.

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. Trinity's take on it? Stack modes allow 2 or 3 drum channels to be triggered by the primary channel's trigger and v/oct inputs. 'Stack Spread' allows for fanning the stacked drums out to taste.

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 trigger 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.
