There is a users manual for the actual VCOs, it can be found HERE
The panels have two VCOs which give tri, saw, processed saw, pulse and pan pulse outputs. The inputs include 1V/oct CV, AC and DC FM, soft-sync, phase modulated sync, pulse width, pan pulse shape and processed saw shape.
There are two DC mixers which can process CV or audio signals.
The VCA is built around a vactrol and is based on early Korg designs with a three input mixer on the front end.
There are two LFOs delivering a variety of waveforms, these have inputs which allow frequency control or can be used as a sync control.
The AR envelope generator has a delay setting and can be switched to cycle or start from a gate/trigger. it can also be switched to deliver very long or short, sharp envelopes.
