SynthEdit supports both MIDI and Audio plugins via the same API....
What SynthEdit MIDI plugins do, is tell the host "Don't call my process()
routine untill an event arrives". I call it Sleep-Mode. It's also usefull
for inactive Audio plugins (e.g. a synth that's not playing any notes).
Inactive plugins use zero CPU. MIDI (should I say Music-Event) plugins
use next-to-zero CPU.
It's easy, efficient, and dosn't involve 'polling' event-based plugins.
Usefull concept???
