I was just trying to use [midiout] to send clock messages (to test a MIDI sync clock in other software).

I've already verified that Pd's ALSA MIDI project is connected to SuperCollider's input port. I can send note messages out of Pd and SuperCollider receives them. So there is no communication problem. (Linux btw.)

The only documentation says that [midiout] sends raw MIDI. So I looked up the clock messages in the MIDI spec:

11111000 = 248 = tick
11111010 = 250 = start
11111100 = 252 = stop

I'm sending these numbers to the left inlet of [midiout] and exactly nothing is happening in SC.

• MIDI communication Pd --> SC is working.
• I already set up the MIDIIn.sysrt function in SC.

So I have to conclude that my input to [midiout] is wrong.

However, I can't possibly figure out what the input should look like based only on the phrase "raw MIDI."

Can anyone clarify?

@ddw_music Your patch should work and maybe you can test it with something other than SC?
There are some refinements and notes to be found here...... https://forum.pdpatchrepo.info/topic/9545/generate-midi-clock-messages-from-pd/3
