"Exquisitely rare little box with one each of VCO, LFO, VCF, and AD envelope. Built-in power supply. The unit is about the size of a small pocket
calculator in width and height, but is about four times deeper. One of the first expanders, maybe inspired by the Oberheim SEM.
Three waveforms; LFO level, rate, beat and vibrato controls; VCF frequency, gain and resonance; EG - attack, decay, sustain, damp;
VCA trigger-controlled audio gate; +/- triggers out; VC Filter in; calibrated and uncalibrated VC in; signal out; trigger in.
This rare expander is in perfect working condition and in excellent physical condition. Very minor scuff marks on the bottom as shown in these actual pictures..."
