[sdiy] FW: FW: Communications with voices in a polyphonic synth

[cheater cheater]

So not so easy after all?

with OSC, you don't have to support anything, so you can just
implement 1 hook and ignore the rest, and nothing bad will happen,
because OSC########## works on packet data. The state machine for that
 is taken care of in the network layer.
