Thanks Victor,

I rewrote the .csd instrument with suggested p-field but I still couldn't get 'csoundSetScoreOffsetSeconds' to work until I sent the score statements programatically, instead of putting them in the .csd, like before.

Anyway... the playback system is working great now and it's much faster/cheaper than I was expecting -- I'm getting 50+ fps on 3d model operations during audio playback, even on my aging laptop -- which is a nice reminder of why dealing with csound's quirks is worth the trouble. Wonderful, wonderful!!! Csound proves it viability once again!

As a side note: I'm loving the discovery that csound adds volume envelopes when starting and stopping playback (no "pops" regardless of where start/stop occurs in the score). It is a big relief knowing I don't have to code that -- especially after banging my head on the wall trying to get the playback system working.

Thanks again,
-andy.f
