Extra oscillator at A 440 for tuning
Noise generator
Filter with cutoff frequency control and resonance control, "keyboard" CV control, and envelope control
ADSR envelope generator which can control the VCA, the VCF or both
LFO with frequency control that can be directed to the oscillator (vibrato), the filter, or the amp (tremolo)... or all at once. The LFO has an LED indicator to indicate frequency.
VCA with initial gain (Hold) knob, which allows you to control the knobs and sliders of the synth without having to hold a note on the keyboard and an ADSR knob to control how much the envelope shapes the volume of the synthesizer.
2.5 octave keyboard
Variety of outputs including RCA and quarter inch. Level control switch, hard or soft tone switch.
Small size and light weight, excellent for playing at gigs when you don't want to tote a large, heavy, or temperamental analog synth to a gig."
