[sdiy] Midi Polyphony question

[Tom Wiltshire]

+1 agree with the points raised.

The new note must be played immediately. Which voice is stolen to do it is down to the particular implementation, but stealing the oldest note is probably commonest.

I've recently developed a Karplus-Strong string synth that measures the amplitude of each voice and when a new note-on message arrives and all voices are busy, the voice with the least current amplitude is stolen.  Other synths are done with oldest note, or round-robin, but in all cases, my code uses voice theft, just with different algorithms to compute which voice to steal.  In no case do I simply drop a note, or let the note play late.
