Hello,

I'm away from my studio, but inspired to put an idea into effect that would necessitate bridging the divide between PD and my larger studio.

I have worked with the noteout and makenote, but for this experiment I'll need to have PD generating the master clock to some Elektron boxes. I've yet to find a sync module, nor have I found any tutorials that cover this.

What modules should I investigate? Is there something that takes metro output and resolves that as midi sync?

Sorry for such a basic question. Again, I'm not at a system that has Pure Data loaded to explore.

Can't you send 248 to [midiout]? That's the MIDI clock byte. Just setup a [metro] to the desired tempo and connect its outlet to a "248" message. Then use a MIDI interface to send that to your other devices.

Perfect. I'll give that a shot (far easier than I was anticipating).

Thank you.

Edit: I see this message is sent 24 times per quarter note, I assume I'd want to multiply the metro bang into 248 by this factor (assuming I send a quarter note tick)? Oh well, I'll experiment.

Most devices expect a clock-start message (250), and then the 24ppq series of 248 clock ticks, and 252 to stop.

Here's a patch I had made awhile back, to test a MIDI-clock-in class I hacked up in SuperCollider. [pd runclock] has all the MIDI logic. You can ignore the OSC control and just click the toggle at the top. Set BPM at right.

midi-clockout-2.pd

It uses pddp/ezoutput~ for an audio metronome; you can just delete that bit, if you don't need to hear a metronome.
