MIDI: from Processing to DAW (Linux)


#1

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);:

processing_midi

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!

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
