Yes, of course! I keep forgetting that fabs() is an FPU operation. :-) (Life's not that nice with ints on most CPUs...)

If you want to make sure you *cannot* overload the CPU with the current net, just have the host test it by turning all silent buffers into cleared non-silent buffers. Varying CPU load is not a problem in RT systems, but non-determinism is. They may look confusingly similar from a practical POV, but they're different things. //David Olofson - Programmer, Composer, Open Source Advocate .- The Return of Audiality! --------------------------------. | Free/Open Source Audio Engine for use in Games or Studio. | | RT and off-line synth.
