[SOLVED] MIDI Pedalboard change after closing web UI

Patchbox OS MODEP
3

I modified the file to add the lines shown above and went through the build and setup processes. It was a bit of a pain setting it up again, but I was able to do so. I can confirm that pedalboard changing starts working as soon as all the active browser instances are closed, without the need to restart the modep-mod-ui service.

However, I later found out that there’s actually an easier way to implement it than going through the entire process I did. You just have to change the contents of one file. So for anyone wanting to give it a try, here’s how they can do it:

  1. Run nano /usr/lib/python3/dist-packages/mod/host.py
  2. Scroll down to line number 1565. You’ll see the following text:
if not self.hmi.initialized:
    callback(True)
    return
  1. Replace those lines with the following lines instead:
if not self.hmi.initialized:
    # typically initialize_hmi takes care of this but without HMI we need to do it manually
    midi_pb_prgch, midi_ss_prgch = self.profile.get_midi_prgch_channels()
    if midi_pb_prgch >= 1 and midi_pb_prgch <= 16:
        self.send_notmodified("monitor_midi_program %d 1" % (midi_pb_prgch-1), callback)
    else:
        callback(True)
  1. Restart MOD UI using sudo systemctl restart modep-mod-ui.

Now you should be able to change pedalboards after closing the web UI, without needing to restart the service. @Giedrius maybe this can be implemented in the next release of MODEP?
