Using PD to generate MIDI notes. Sending through IAC bus into Pro Tools. If I play a chord, the root note will be recorded far earlier than the rest of the chord. I suspect poor MIDI timestamp compatibility between PD and Pro Tools.
Funny thing is doing this via PD -> IAC -> Garage Band, it works fine.
Also, going PD -> IAC -> Kontakt Standalone Instrument -> IAC -> Pro Tools works fine too.
Any suggestions on making PD -> IAC -> Pro Tools work correctly?

This is my version of a MIDI IAC bus. Fixed my problem! Not the most elegant solution, but it works!

Now I can finally stop wasting my time troubleshooting and get back to making art. Phew!
