Circuit Overview:
     A simple 1 vco monophonic synth with very basic controls (A-D envelope, VCF LF and HP cutoff dual sliders they call 'traveller', triangle, square, saw and two chorus effected waveforms, LFO and repeat rate controls and some useful toggles for a preset attack bend, lfo delay, sustain (release preset) and Exapand (applies the VCA EG to the VCF) and "Bright" which added some resonance. Great sounding little units.

Service Tips:
     Typical cleaning issues. Haven't heard of any specific typical failure otherwise. The service manual was hard to read, hoefully a better one will arise.

I have drilled replicas (instead of flat holes for shaft). Super nice precise mold. - $7 ea.

I believe you'll draw mostly blank looks from Korg on these units. I have some parts that are the same so feel free to ask what the current stock is on a given thing. Some of the less common parts are getting quite hard to find though. THings pop up on ebay now and then.. Contact
