Hello. Does anybody here has any successful experience sending MIDI messages from pure data to Ableton (11) via IAC bus on Mac? Midi indicator in the top right corner actually lights up, so the messages come through, I guess, but there's nothing going on on the individual MIDI tracks. I've also tried doing the same thing with ORCA, but there nothing works at all (though I haven't spent much time on that)
Also sending messages from Ableton to pd works just fine.
(There's a ton of tutorials on IAC in Ableton, I know, but literally all of them are about using Midi tracks for automation inside Ableton)

yeah I've fought with that - what's annoying is they show up but you have to dive deep into the Audio Midi setup to find it and checkmark the device to be Online once.. and then it will work.

I also like to go in and rename them to something more sane like ToThisIn and FromThisApplicationOut even tho they can be used either way, it's more for my sanity, I do the same thing with loopMIDI in windows,

fun fact - you can keep making more ports here as well just click the +.

Uhhh.... Creating the second bus did indeed do the trick

Actually, I'm taking it back. MIDI stopped working again. I've tried both IAC driver and MidiPipe in VCVRack and Vital and they work just fine, so it begins to look a lot like some bug in Ableton

yeah probably, coming from other OSes to mac later, I almost never have problems with coreaudio/coremidi.

MIDI Monitor is my goto on mac for diagnostics/ snooping - it can be set up to act as a destination too I think that works like a virtual port

another virtual port program is midi patchbay
