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: http://www.borg.com/~jglatt/tech/midispec.htm

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 http://www.audionerd.com/projects/pd/tips/midi_clock_out

Hi, I'm new on this list and new to PD.

I wanna sync a PD patch to an external Sequencer via Midi. I thought about using Midi-Clock but I recognized that the sysexin-Object doesn't work under OS X. Maybe there's an external which does the same and does work with OS X?

Or do you have an Idea how I can sync without Sysex?

Thanks,

Veit
