Thanks for the information. Could you be so gentle to try the poliphony
in realtime with your machine? In the 1.7 version is included files
miditest.orc and miditest.sco.
Please Try this simple instr with ar=44100 and kr=441, and then with ar
=40000 and kr=400 (-e flag must be actived for allowing non-standard ar
and -P99 if you want use midi sustain pedal)

holding down the sustain pedal and playing notes once a time with my
master-keyboard, I achieved the following realtime performace before
incurring in dropouts with my P133:
at sr=40000 and kr=400 I achieved 50 oscili or 90 oscil polyphony
at sr=32000 and kr=320 I achieved 64 oscili or 126 oscil polyphony
at sr=16000 and kr=160 I achieved 144 oscili or 280 oscil polyphony

I'm curious to know how PPro behaves!
Thank you
bye and happy csounding!
