Hi Mike, thanks for that, maybe this works too.
Since my own Poly-800 is mostly malfunctioning right now, would you want to try the mod yourself?
If so, here is what should be done:
First, get short sequence running with a few different single notes.
Then, take a wire and connect one piece to Pin 7 of the left most chip of the Chorus board. Keep that one connected.
Touch the other end of the wire to Pin 14 of the same chip, and let go. Try to do the ON/OFF contact on Pin 14 more or less in sync with the sequence notes.
You should hear some form of simple Karplus-Strong synthesis, i.e. Physical Modeling by waveguide, which provides for rather realistic string sounds.
And best of all, it's pitched correctly!
