@lucayala welcome to the community!
First off, modifying the UI of modep is possible but could be a difficult and time consuming task.
Beyond that there are a couple of options:
- Use the PiSound app if you have an android device. You’ll need to put the pedalboards that you want to be able to select from in a specific bank.
- You could try out my node-red dashboard app that can be installed on the pi: Node-Red and MODEP
I made a diy midi controller and am in the process of expanding that code to allow for selection of a pedalboard but that project is not progressing very quickly.
