3× single-cycle wavetable-lookup oscillators per voice

3 independent LFOs

3 independent envelope generators which can be programmed to modulate any number of parameters.

8-track MIDI sequencer that can run either its internal sounds, external MIDI equipment, or both, with a capacity of 24,000 notes (expandable via cartridges). It provides quantization, step-editing, primitive forms of copy/paste editing, and can be synchronized with external MIDI or tape-in clock.

Can store 40 presets internally, and features a cartridge slot for additional storage capability

Each oscillator can be independently volume-controlled via its dedicated digitally-controlled amplifier, and modulated. Oscillator amplifiers provide room to be overdriven, and thus produce moderate analog distortion as an additional effect on, for example, synth leads or organ sounds.
