[sdiy] Midi Polyphony question

[Scott Gravenhorst]

This is not a simple subject and in my view depends on exactly what the 
synth is doing.  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.
