MIDI: from Processing to DAW (Linux)


Hi everybody,

I’ve created a MIDI control GUI in Processing that I would have liked to link to Reaper to control some automation by sending MIDI CCs (using the MidiBus library).
Unfortunately, different from what I expected, I’m unable to exchange MIDI messages between the GUI and the DAW.

I’m using Jack and a2jmidid.
This is a screenshot of the following processing code line myBus = new MidiBus(this, 1, 2);:


This is a screenshot of my current audio midi setup:

Is there a way to show up the “Java midi output” in Patchage (don’t know another way to explain it)?
How can I make my MIDI messages from Processing being sent to my DAW?

thank you very much for your support!

Sending MIDI information to my DAW

Unfortunately, JavaSound on Linux only supports hardware interfaces. I haven’t done this for a while, but you’ll probably have to look into the snd-virmidi module to create virtual hardware ports.

Another option would be to send MIDI directly through JACK using JNAJack, rather than MidiBus - see
