Synth modules

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: Transpos lets you transpose three CV channel with a single source.

Adder:

The voltage of each CV input can be varied by plus or minus two octaves depending on the switch and the potentiometer of each channel. Transpos uses precision regulators: for example if we increase by a fifth with the switch on "+" we reduce it by a fifth when we pass on "-".

Transposer:

The 1V/o CV input will influence each of the three channels. By turning the CV potentiometer you can globally increase or decrease the transposition of the three channels at the same time.

Notes: A passive multiple that fits nicely with the Klavis range.

Notes: Clever four-channel utility module designed to make it easier to achieve perfect oscillator tracking and transpose CV signals. Also includes some neat quantising and portamento features.

Supplier notes:
The CalTrans solves issues encountered when playing tonal music with a modular system: tracking problems, curves unrelated to Volt per octave ratio, limited octave range, cumbersome transpose, ...

The CalTrans corrects and expands the range of troublesome VCOs and brings V/Oct tracking to anything that oscillates.

Besides calibration, the CalTrans offers live play features. Each channel can be quantized and any combination of them transposed jointly.

A pair of rotary encoders with detent allow an precise selection of octaves and semitones.

VCOs whose tracking doesn't go high enough to follow the leader will see their pitch repositioned in their highest possible octave so that the global harmony is unaffected.

You can add a pinch of portamento and glissando to each channel and save the whole in user presets.

Notes: Digitally-controlled full-analogue path Granular + Multimode VCF

The Grainity brings a unique and never-heard-before concept to the world of analogue VCF.

While being based on analogue filtering only, the Grainity expands and enriches the sound in creating subharmonics, harmonies, unison, flanging effects and formant filtering all at once.

The module presents two sections, the granular filter itself and a typical multimode filter, each with its own output.

A third output offers a mix of both filter paths. Numerous controls and CV allow a very wide palette of results.

What is the Grainity

Granular?

The word granular was chosen for this filter module in relation to the concept invented by the composer Yannis Xenakis, and which is described as assembling small chops of sounds - he called grains - according to a pattern.

This is exactly what the Grainity does, no more no less ... but, digital control allows doing it in ways that are decades away from what tape and scissors allowed at the time.

Technology wise ...

In the granular section, the incoming sound cycle is determined in order to step through various filtering and phase variations of itself according to predefined patterns called structures.

The controls allow alterations to the cycling phase, cycling frequency offset (tuning), structure selection and frequency division of the filters cycling. This comes in addition to the usual filter frequency and resonance controls.

What the Grainity is not

Technology wise ...

Despite relying on a microprocessor, the Grainity is not a digital audio processor. At any time, the sound remains in the analogue domain and goes through analogue circuits from in to out.

The digital processor does not convert or generate audio signals; it is there to control the analogue circuitry and manage the interface and display.

Sound wise ...

Several digital modules offering granular processing rely on the layering of sound grains, which leads to blurry and cloudy textures.

Layering of the grains is a late addition to the concept of granular synthesis and is not a mandatory feature of the concept.

The Grainity does not use delay lines or sampling memory but is nevertheless true to the foundations of the granular synthesis concept.

The granular VCF in the Grainity is unconventional in that, most of times, it is not filtering the sound in the common expectation of removing something. Typically, the granular process adds more than it removes by expanding both the lower range, creating subharmonics, and the upper harmonic contents in multiples ways.

Notes: Focused versatility seems an oxymoron when describing the features that led us to design the Mixwitch.

With only a pinch of mixing, inverting and controlled switching, we brew up a plethora of combinations and uses.

This is voltage processing magic!
The Mixwitch design comes from a frustration with attenuvertors (bipolar attenuators-inverters) whose off (neutral) position is difficult to retrieve, especially in live situations.

We went for a digitally-controlled analog path where polarity inversion would be at the touch of a button. So, the usefulness of attenuating/inverting can be realized by turning the pot down, swiftly pressing the inversion button and reopening the level. The zero level is where you expect it, with the pot full down.

Once we had a clean polarity control, we easily added a mute function offering the benefit of pre- adjusted pot settings ready to be activated at will.

The next step was to bring something extra, useful and creative. There are plenty of analog switches controlled by a clock; but arbitrarily selecting an input with a voltage is less known. Having both control capabilities combined with our specific mixer features creates a unique fusion: welcome to the Mixwitch !

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.

More than ever, the Twin Waves is versatility at its best.

Notes: Another clever one from Knobula, this chord-based sequencer/arpeggiator adds versatile harmonic options to your creative process. Pair it with the Poly Cinematic module for best results.

Supplier's Notes:
Generate extraordinary chords without using a keyboard.

Chord Pilot introduces a whole new take on the task of chord creation and performance offering 192 chord memories, a strummer, an arpeggiator and an 8 step chord progression sequencer, all in one compact 12hp package.

Knobula have thrown away the music theory rule book and instead offer a module that encourages the curious mind to discover alternative musical pathways, whether for generative patches or for EDM riffs.

To generate a new chord, Chord Pilot uses a series of controls that alter the width and spread of 'fingers' over a virtual keyboard before conforming them into a variety of musical moods from the pure and harmonious to the terrifying and cacaphonic.

Like all Knobula products, Chord Pilot has been designed primarily with performance in mind, to inpsire by experimentation, to lose yourself in the moment, and to occassionaly generate impossibly hard to play super chords.

With the ability to store and transfer chords in sets of eight, Chord Pilot makes a great companion module for Poly Cinematic, but it is equally at home serving any poly synth with a midi input.

Discover Chord Pilot, your guide, navigator and explorer to a whole new universe of musical harmony, and beyond.

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.

Notes: This new device is a powerful new CV controlled effects unit for your electronic music setup and pairs extremely well with the KOMA Field Kit.

- Looper
- Frequency Shifter
- Sample Rate Reducer/Bitcrusher
- Digital Delay
- Analogue Spring Reverb
- 4 Channel VCA Mixer
- 4 Step Mini Sequencer
- Envelope Generator

All of this, combined with the new 4 Channel CV Interface which allows you to route four CV signals throughout the device, means an incredible control over sound and timbre and a great addition to your mobile performance rig.

The Field Kit FX is built up from 7 separate functional blocks all focused on mangling and changing incoming audio and CV signals. They are designed to operate together as a coherent addition to our Field Kit Electroacoustic Workstation or alternatively together with other pieces of music electronics with the ability to use control voltage signals.

Notes: An ultra-compact 10HP VC filter with bags of personality. Camber can be treated as a subtle, non-intrusive sound design tool, or something much more lively.

Camber is designed to be a fun, tactile filter with a small footprint. It's sound is neutral enough for basic filtering without a fuss, with a much more aggressive tone available using high resonance settings in three-pole mode.

Filter Core

The core of the filter is based on a state variable topology using 2164 VCAs and 1% tolerance integrating capacitors. Resonance and feedback control is provided by the fantastic circuit design originally by Neil Johnson "Voltage Controlled 3-Pole State Variable Filter" recently made available in Sound Semiconductor documentation.

Operation

Camber is switchable between low pass and high pass responses with one pole (6dB) and three pole (18dB) flavours of each. It has full CV control of both cutoff frequency and resonance amount. The input is DC-coupled allowing LFO and CV signals to be routed through the filter. The filter will also act as a simple oscillator producing a clean sinusoidal signal with the resonance control turned *almost fully clockwise, and no signal at the audio input. Dialling in the resonance so that it is just under the point of self-oscillation allows the filter to be "Pinged" by sending gate signals to the audio input. This is useful for tuned percussion sounds and FX.

Notes: Lush analogue EQ switchable between tilt and Baxandall high-shelf configurations.

Perform a variety of mixing and sound design duties ranging from subtle brightness and clarity adjustments to low-end rumble removal, boosted low-pass filtering and sweep EQ.

In the default tilt mode, turning the control knob clockwise simultaneously boosts treble and cuts bass. Turning anti-clockwise boosts bass and cuts treble. These boosts and cuts are pivoted around the mid-range. With the control knob at 12 o'clock the frequency response is neutral.

With Baxandall high-shelf mode enabled, turning the control knob clockwise past 12 o'clock introduces and gentle high-shelf EQ weighted around the upper mid-range. Turning the control knob anti-clockwise results in a wide high-shelf cut with subtle bass and mid-range adjustments.

Patching the channels in series allows for radical sound shaping and band-pass responses. Each channel provides up to +/- 8db of low and high-frequency gain control, summing into a low noise output stage. Hot input signals over 15vpp are saturated by active Zener diode clipping.

Notes: Tilt is the first in Laine's series of core modules, which will take cues from the main product line and strip back the features so both the module width and cost can be shrunk dramatically.

Comprising an 'Ambler' style tilt EQ network similar to the 'Stilts' topology, Tilt allows simultaneous cut and boost of low and high frequencies using a single control.

Tilt control circuits are known for the transparency of their cut and boost curves, coupled with the inherent emphasis gained from cutting one end of the frequency spectrum whilst boosting at the opposite end.

It sounds pretty good on all audio source material but is especially suited to tracking drums, guitar and lead, or manipulating effects sends and returns.

With the control knob at 12o'clock the sound passed is neutral. Turning the control knob clockwise will boost high and cut low frequencies pivoting from a fixed mid-range point. Turning the control anti-clockwise below 12 o clock will in turn boost low frequencies and cut the highs.

In addition to the EQ there is a soft clipping network which will begin to saturate signals over 15 volts peak to peak.

Tilt uses the same high quality OPA op amps, Alpha pots and ENIG PCBs as found in our main product line.

Notes: Winnows, a dual VC resonant filter with damping.

Winnows brings radical resonant filtering to the 1U row. Make your basslines growl like it's 1999. Create clean resonant tones and layers, tuned percussion, steep filtered peaks, vowel filters and more. Each filter channel comprises two state variable filter cores, the first producing a 2-Pole band-pass response, with resonance and self-oscillation amounts set by a 3-Pole feedback network. Signals are then routed through a 1-Pole low-pass damping stage to remove harshness if required. This can be routed to the channel output, or switched and routed through a second series of resonant SVF and 1-Pole LPF damping stages. This circuitry is identical per channel.

Features and uses

Steep and spiked or wide and smooth, resonant bandpass filters
Zone in on and reinforce a sound's dominant frequency, create overtones using both channels
Create sharp resonant peaks, dull or remove any harshness with VC damping
Use the resonator as a sound source by shaping and triggering tuned percussion tones or kick drums
Per channel: 2 x VCA based SVF, 2 x 1-pole damping LPF, 1 x 3-Pole resonance core
Identical circuitry per channel, CV and audio jacks are normalled between channels
Combine both channels in series for vowel filter responses and creative filtering

Notes: Motomouth is an analogue 3-Band, Sedra + Espinoza Bandpass Filter (DABP) with resonant frequencies that are tuned to the same resonant frequencies found in the human mouth and nose cavities, and these can be varied, independently, to form different 'mouth shapes,' to emulate vowels such as A, E, I, O and U. Motomouth can emulate 16 vowels and 'morph' or 'glide' between each vowel using a single Control Voltage input (1V/Oct), and a Gate to 'snap' to each vowel when required.

Two of the bands (F1 and F2) are used to form the mouth cavity, and the third band (F3) is used to form the nasal cavity, which is reasonably static. Varying F3 makes little significant difference 'in the mix,' but having it is important.

The single Control Voltage is decoded to control F1 and F2 independently, because the frequency bands for each vowel are not proportional to each other over the vowel range. So Motomouth has learned how to 'speak,' so to speak, but it still needs to learn more, and that's where you come in.

Notes: The basis of the module is a version of the transistor ladder with low-end compensation at resonance, to which Machineroom have added aggressive Overload and linear VCA. Thanks to three audio inputs, FILTH can work with polyphonic patches, if you add Trilobite (or another triple osc) and ADSR to it, you will get a paraphonic synthesizer. 2 VCA inputs in the classic case allow you to use loudness envelope and voltage offset (for example, velocity) at the same time, but there are many more options for their application.

Works in LP/HP and 12/24 db modes

In the 24db mode, the filter self-oscillates and can act as a sine generator with perfect pitch tracking in the range of 5 octaves.

Despite the name, without overload, the module can be used as a vanilla filter, but its brutal version is generally more preferrable.

Notes: MachineRoom PRODIGY DUAL VCO is an analogue dual oscillator based on the legendary Moog Prodigy synth schematics. MachineRoom improved Bob's design by incorporating ICs with better thermal stability, increased the range of secondary oscillator, and also added cross-modulation possibility. As usual for this limited run of full-analogue handmade modules, MachineRoom used only thru-hole components.

The module features 3 octave registers and 3 waveforms per oscillator.

OSC1 generates SAW, SQUARE, and TRIANGLE waves with 8, 16, 32 octave registers.
OSC2 generates SAW, PULSE, and TRIANGLE waves with 4, 8, 16 octave registers.

Unlike the original version, PRODIGY DUAL VCO allows switching OSC2 to the LFO mode to modulate OSC1 or other parameters (LFO range is from 0.1 Hz to 8.6 kHz). Precise pitch tracking is up to 7 octaves.

PITCH control has a range of +/- of 1.5 octaves with a central point (to have the ability to quickly return to the initial frequency with precision). The rise/fall time of the GLIDE/SLEW is up to 5 seconds

HARD SYNC switch allows syncing the phase and frequency of oscillators.
LINEAR FM input has a built-in attenuator.

OSC2 UNISON control has a range of +/- 7 semi-tones (increase/decrease relative to the Detune central point).
OSC2 V/Oct Tracking switch activates or disables the OSC2's LFO mode. When disabled, OSC2 stops v/oct tracking, and the UNISON knob becomes a control for the LFO frequency.
OSC1 - OSC2 FM switch enables OSC2 as an OSC1 modulator.

When HARD SYNC is switched ON, Pitch/Sync knob controls the phase of oscillators.

The output level of each oscillator is about 3.5V which allows passive mixing. PRODIGY DUAL VCO is analogue so should be allowed 5-7 minutes to warm up before use.

Skiff-friendly design.

Notes: TRILOBITE is a triple oscillator analogue module inspired by the original Moog schematics and made with thru-hole components only.

The module features:

- 4 octave ranges
- 3 waveforms (triangle, square, saw),
- UNISON (FINE) control with a range of +/- 12 semi-tones
- Independent LIN FM and PWM inputs with attenuators
- White noise source

Independent audio output is provided for each oscillator. A mixed output is also present featuring a level control.

We are recommended to use independent audio outputs to avoid distortion, in this case MiX output works as WHITE NOISE source with attenuator.

V/oct input of the first oscillator is normalled to all 3 oscillators, so OSC2 and OSC3 would track it too, however, connecting other signals to the other V/oct inputs make each input independent.

The minimum frequency of each oscillator is as low as 3Hz which makes it possible to use them as LFO.

Each oscillator tracks up to 9 octaves.

V/Oct range: 0-10 V

NB: Trilobite as is a full analogue module so should be allowed 5-7 minutes to warm up before use.

Notes: The Dual Stereo Gate (DXG) music synthesizer module is a Dual Stereo Low Pass Gate and Mixer. It follows in the footsteps of the QMMG, Optomix, RxMx, DynaMix, and LxD. Unlike its predecessors, the DXG is specifically oriented around mixing stereo signals, making it an important addition to any system containing modules like XPO, QPAS, Morphagene, Mimeophon, and other stereo modules by Make Noise or others.

Unique to the DXG is a new low pass gate circuit that does not use vactrols. This circuit is 100% analogue and its response was arrived at after many months tailoring it to meet or exceed the expectations that have been set by all the vactrol low pass gates that Make Noise has created over the years.

In the past, Make Noise produced the Dynamix module and Dynamics circuit in the 0-COAST, both of which are vactrolless LPGs; however, the DXG is a completely new approach which better implements the gentle single pole filtering of a low pass gate, while also emulating the slow decay and memory of the vactrol based low pass gate. This new circuit makes possible the consistency of response necessary for versatile stereo use, while also keeping the module small and affordable so that it can be a key part of just about any modular system.

As on all of Make Noise's low pass gates, the DXG's Control parameter is used to set both the amplitude and the frequency content of the sound that passes through it. The control parameter tends to open faster than it closes, imparting a subtle decay phase onto any envelope shape that is used to modulate it.

Unlike previous low pass gates made by Make Noise, all the DXG's inputs and outputs are stereo. Each set of inputs is normalled so that the left input can be used for a mono signal, sending a copy to both left and right outputs. The Auxiliary inputs are also a stereo pair with mono normalization. These normalizations allow for the DXG to be used as a simple three channel stereo mixer, with one or two of the channels additionally being used for dynamics control and note event generation. The Aux inputs can be used to chain together larger decentralized mixes using additional DXG modules, or X-PAN, Optomix, modDemix etc.

Features

- Make Noise's first Stereo Low Pass Gate

- Vactrol-free design for classic Low Pass Gate sounds, but with the balance and consistency needed for true Stereo

- Fully Stereo i/o for easy integration into a Stereo-equipped modular synthesizer

- All Left inputs normalled for easy use with Mono signals

- STRIKE Input allows use of Gate signal to trigger Low Pass Gate circuit, creating "plucking" or "pinging" sound from any Gate

- Summing stage with Stereo AUXiliary IN allows for chaining of multiple units, creating larger mixes

- Part of a decentralized mix console integrated throughout the system along with X-PAN, Optomix, XOH, etc.

- Pairs well with XPO, QPAS, Morphagene, Mimeophon, Spectraphon etc.

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.

Notes: Arkan

Dual Voltage Polarizer

You may have heard this before: "You can never have enough VCAs". A voltage polarizer (also known as a bipolar VCA or a 4-quadrant multiplier) is often viewed as the VCA better suited for CV. As it can be used as a unipolar VCA and it allows you to invert a signal when it is modulated with a negative voltage. Resulting in interesting movements in your modulations.

What sets Arkan apart from other voltage polarizers is the curvature control, a feature usually only seen in unipolar VCAs. By taking a different approach to the classic voltage polarizer circuitry, Malstrom have devised a unique solution that provides a new way to shape your audio and CV. The non-linearity of the polarizer also makes Arkan really good at reaching silence when presented with a 0V CV signal.

At audio rate, Arkan acts as a ring-modulator with four controls to change timbres.

Boosting adds odd harmonics (symmetrical distortion), while offsetting adds even harmonics (asymmetrical distortion). The modulation curve changes ring modulation sharpness, and modulation strength determines the carrier dominance.

Two identical channels with carefully selected features will make Arkan your go-to modulation control hub. Arkan is especially useful for common utility duties such as mixing, scaling, inverting and offsetting. As well as CV modulation, feedback patching, and waveshaping. All this makes Arkan a very versatile tool that will certainly have a place in your patch!

Features (per channel)

- Input attenuation with inverter switch gives you more precision and range, with voltage inversion and quick silencing.
- Bias input with attenuverter control to offset your input signal or mix/invert another signal.
- CV input with curvature control allows you to shape the polarizer and improve its 0V attenuation.
- CV modulation control to fade in the modulator, allowing you to determine the amount of modulation.
- Voltage gain and polarity led indicators showing you exactly what is happening under the radar.
- Output normalled internally and externally (to other Arkans) to easily mix signals.

Additional features

Optional signal boost (x4 / +12dB) via switch on the PCB to increase voltages when needed.
