6 years ago It's designed to translate MIDI from an external controller. If you want to use hardware lines on the Pi as controllers you'll have to write your own code to do so. You can build on the low level communications code I've written - that was the hard part.
does katan-midi-bridge force me to use an extra midi controller? I am hoping to get this set up on my pi and use strictly the pi to control my katana amp. Reading through your repo I am still unclear as to whether or not using an external controller via midi to usb is required or simply a feature that you support.
