Hey Memo As long as you don't read from inputs or generate output needlessly, having execute: atTime: withArguments: called in QCPlugInTimeModeIdle should be of trivial cost, and would be the 'proper' way to do this. As far as I can tell, QCPlugInTimeModeIdle is there for exactly this sort of functionality.
Have you experienced a performance hit doing it this way? I don't see the reason for your (or Christopher's, I see he just replied) aversion to it.
