[PD] SysEx Data and MacOS X (Sync-Problem)

[eric skogen]

Is Pd going to control the sequencer as the master midi clock? If so, 
set up a midiout object and send it the decimal commands for MIDI clock 
as messages:

250 will arm the external sequencer
248 should be sent 24 times per tick (generally, 24 times per quarter 
note) to advance the sequencer
252 will stop the external sequencer

details are here:

I haven't tried MTC or any other form of sync, but midi clock was enough 
to sync a drum machine to Pd at a show once with good results. The 
difficult part is generating a steady clock, and matching the clock to 
the latency of your patch.

I'll post an example at
