MackieOS doesn't have to operate in the RT league for DSP, because as
you point out, thats all done on slave DSPs. But the "pentium class
(133MHz)" host/master processor *is* responsible for automation data,
motor control for the faders, MIDI time code handling and variety of
other tasks that all call for pretty good (say, 5ms or better)
latency.
