Probably to make MIDI control as deterministic as the audio
processing. (Not much point in running a synth with small buffers and
SCHED_FIFO otherwise.)
Another motivation would be to avoid having MIDI timing quantized to
audio block granularity under heavy audio CPU load. This would make
sense only if events have to be timestamped in the context of the
MIDI thread, and then it would require that the MIDI thread gets
higher priority than the audio thread(s).
