Inside the Korg Polysix. Analog synths with Storage


YouTube via sounddoctorin. via Nusonica.
"Bob Weigel of http://sounddoctorin.com goes over the layout of some of the more significant components in the Korg Polysix, a synthesizer which sold around 22,000 units produced from 1981 to 1983 or thereabouts. Korg simplified and cut cost in many ways on these units but they stand as one of the few fully analog (with a discrete VCO for each voice if not two) polyphonic synthesizers ever mass produced along with the Prophet 5/10, the Oberheim OBX, OBXa, and OB8, which had BOTH memory and full editing from the panel without toggling through menus etc. Later a MIDI retrofit was also introduced bringing this unit and a rather nice one I hear. Hopefully I can get mine working that I just purchased broken :-). That unit is not shown in this demo though. The MIDI board lays over the top of the CPU's and a connector actually goes into the cpu sockets and the cpu's set on the new MIDI retro board."
