MCO:

Compact Multi Synth Voice

The MCO (mk II) is a highly versatile digital VCO and voice module inspired by 90s/00s digital synths shrunk into just 6HP.

It offers a broad collection of unique, high-quality synth voices, each with extensive, customizable parameters. These parameters can be directly controlled or modulated through assignable internal and external sources. Certain per-voice parameters support audio-rate modulation, including FM, sync, and DSP. Each voice also supports up to four-voice chords, external-triggered envelopes, multiple LFOs, and dual audio outputs for comprehensive desktop like synth functionality.

Each voice includes factory presets as well as the ability to store and recall user presets. All states are preserved across power cycles.

The MCO is designed to be familiar, quick and easy to use with a high resolution colour display and a rich visual user interface.

A USB-C connection allows for easy firmware updates, user wavetable upload and device config backup and restore. Axon expander modules are supported to increase CV control options.

Voice Programs

The MCO contains 8 different fully featured synth voice engines which cover many types of digital synthesis. These include:

DigiWave - Wavetable Oscillator

The DigiWave is a wavetable based voice that produces two simultaneous morphing waveforms from a factory or user uploaded wavetable bank. The waves can be combined in multiple different ways with pulse width modulation available across all shapes. A secondary one octave down sub oscillator output is simultaneously available with four possible wave shapes.

This flexible voice expands on the original MCO’s sound and unique feature set with the same wavetable and sub options.

ToneSum - Additive Synthesis

The ToneSum is an additive based voice that produces a range of physical and organic sounding tones entirely from twelve combined sine waves. It allows complex and nuanced tones to be shaped intuitively from familiar EQ and filter style spectrum controls as well as other unique options such as harmonic distribution and detuning.

This distinct voice can produce anything from bright, glassy sounds to woody plucks or eerie inharmonic sweeps.

BC8000 - Variable Mode Digi Synth

The BC8000 is a multimode synthesiser voice inspired by the specialty oscillator types available in the classic JP8000 synthesiser. It can produce an array of different textures and sounds from its Supersaw, Triangle Mod, Noise and Feedback oscillator modes. A built in resonant multimode filter and dedicated pitch-mod LFO make this voice the likely choice for organic and expressive sounds.

Sylon - Vocoder

The Sylon is a feature packed vocoder and FFT-based-reconstruction voice that produces rich robotic and harmonic sounds based on any source patched to the MCO’s External input. Similar to the ToneSum, it includes simple EQ and filter style controls for intuitively designing exciting, dynamic vocoder or FFT sounds. The additional Crush and Slew parameters introduce digital character and dynamics control respectively for further uses such as a unique percussion processor or spatial effect.

Virtana - 90s Analog

The Virtana is a 90s style dual oscillator ’virtual-analog’ synthesiser voice great for producing classic subtractive sounds with bright digital clarity. Along with controls for oscillator wave shapes, tuning and mix, it also includes a resonant low pass filter and special Drift control for adding subtle vintage style pitch instability. The Virtana naturally excels at thick detuned bass, dual oscillator chords, stirring PWM sounds and bright leads.

Oomph - Bass Synth

The Oomph is a one of a kind kick drum and bass synthesiser voice designed to produce powerful modern kicks, basses and tonal percussion sounds. It can operate both as a free running bass oscillator or as a drum voice when a ’Trig In’ is assigned to an envelope and a trigger is patched (revealing extra parameters).

It includes a specialised percussive pitch envelope with ’Click’ and ’Thump’ settings for sculpting transients followed by a ’Sub’ setting that produces a natural pitch droop over time as the sound decays. In addition, on board FM and numerous distortion modes take sounds further into experimental territory.

SID GUTS - SID Chip Emulation

The SID GUTS voice is a C64 style SID chip emulation based on our (now out of production) SID GUTS and SID GUTS DELUXE modules. This classic voice offers distinct lo-fi digital charm with aliased waves, pitched digital noise, ring mod and a slower update rate that produces idiosyncratic imperfections in the sound for tones reminiscent of classic 80s computer game music.

AEIOU - Vocal Synthesis

The AEIOU voice is a vocal synthesis engine that uses band pass filters to mimic the formants of a human voice for a range of phonemes. Morphing between the two phoneme parameters using LFOs, the built in envelope or external modulation can produce any sound from robotic whisper textures, to background chatter, to simple pronounced words.
