Hello @srl0! Changing both snapshots as well as pedalboards via MIDI is possible using MIDI Program Change (PC) messages. First you need to edit the file /var/modep/profile5.json. It should have the following lines:
“midiChannelForPedalboardsNavigation”:0,
“midiChannelForSnapshotsNavigation”:0
You need to change those values so that they correspond to the channels you want your snapshot and pedalboard change PC messages to be received at. They need to be different. You can set them to any channels you like, but it seems like a lot of people tend to set them to channels 15 and 14 for pedalboard and snapshot changes respectively. A PC 0 switches to snapshot 1, PC 1 switches to snapshot 2, and so on. Similarly, for pedalboards, PC 0 switches to the first pedalboard in your list of pedalboards, PC 1 to the second one, and so on. One important thing to note is that pedalboard changing works only when the web UI is closed. And by default, once the web UI has been opened, you need to restart all the modep-mou-ui service before it starts working again.
Hope that helps!
