Archive of the former Yahoo!Groups mailing list: Discussion about the Korg PolySix synthesizer

And one more update:

If a note is held down and the "hold" button pressed the pitch raises also
by roughly 1 cent.

I'm starting to suspect this has something to do wih the fact that the
Polysix has no separate power supplies for digital and analog 5V. Most
instruments under computer control have separate regulators and rails for
digital and analog supplies.

I also wonder if the additional +5V supply line going direct from the power
supply to the LFO LED was an attempt by Korg to deal with a similar problem.
