Actually, I see advantages in both methods. The MIDI way is certainly
more appropriate for realtime, but Csound's approach makes many things in
synthesis much easier (or even possible). For instance, try designing a
MIDI-controlled sound that crescendos linearly from zero volume at note-on
to maximum volume at note-off. Impossible unless you can predict the
future. I guess both MIDI and Csound use models that are well-tailored to
their respective original purposes.

Good point. Don't throw out the baby with the bathwater.

I understand what you're saying, but I can't think of an example where the
difference _would_ be dramatic. It comes out about even each way --
sometimes merged is more useful, sometimes separate. Please prove me
wrong, so I can make a good decision.
