<clueless question> roughly what latency/accuracy requirements does the
MIDI clock have, and why is it an advantage if Linux generates it? What
generates it otherwise - external MIDI hardware? Or was the problem
mainly not latency/accuracy but that Linux couldnt generate a
finegrained enough clock?
