Voltage-controlled monophonic digital sound source

Sound source… like an oscillator? Not really. Most of the timbres it generates are so complex that approaching them with a classic analog modular setup would require a full case of oscillators, filters, VCAs, waveshapers and ring-modulators – that’s why they call it a macro-oscillator – intricate digital synthesis algorithms wrapped in oscillator’s clothes.

Each synthesis algorithm is controlled by two voltage controllable continuously variable parameters, Timbre and Color. Very often, these parameters simultaneously affect several dimensions of timbre, creating very complex movements which would be hard to generate with a traditional setup.

Voltage-controlled digital oscillator featuring 33 synthesis algorithms from 8 categories:

analog VCO emulation (morphing through triangle/sine, sawtooth, square, pulse waveshapes)
direct digital synthesis
vowel/formant synthesis (VOSIM, vowel synthesis, additive harmonics)
2-operator FM
physical simulation of tubes and strings
wavetable synthesis with smooth XY interpolation
filtered/coloured/pitched noise
granular/particular
Bonus features: Auto-calibration, note quantizer, sample/bit rate controls, basic AD envelope to modulate the timbre when receiving a trigger.
