voice architecture
two voltage controlled discrete analog oscillators
waveforms: triangle; sawtooth; variable width square. all waveforms output simultaneously. osc 2 to syncs to osc 1.

dedicated mini and quad discrete filter systems
streamlined internally mounted integrated filter board designs: option #1: mini filter. option #2: mini; s.e.m.; 303; 2600.

discrete analog ring modulator
external carrier input for external signal processing (bypasses oscillator 2 function).

discrete analog distortion circuit
per patch programmable level control.

three multiple stage envelope generators

attack; decay; sustain; release with inverting and multiple triggering. envelope 1 fixed to filter frequency. envelope 2 fixed to amplifier level. envelope 3 is assignable. oscillator 2 audio frequency modulation (cross-mod). destinations: osc 1 frequency; filter frequency.

two low frequency oscillators
waveforms: triangle; sawtooth; reverse sawtooth; square; noise; random. parameters: destination; depth; key trigger; phase; midi sync.

additional features
white noise generator. external input processor. exponential glide. parameters: time; autoglide interval; destination.

midi specifications
in and out. receives: program change; bank select; glide on/off; glide time; volume; sysex. controllers: dynamics; modwheel; bender; pressure (each with one destination and amount). fixed continuous controller assignments for all key functions.

modulation destinations
