Discussion about the Korg PolySix synthesizer

The actual waveform generation happens on KLM-366, the large rightmost
board. You'll see the six voices on the right part of it. This board also
takes care of the key assign duties and the arpeggiator.
Do the LED's for the six voices light up for each key pressed? Press a
single key repeatedly and the voices should become (visibly) active one
after another.
