I need to send specific bytes over USB/MIDI. How can I accomplish this?
I want to program a midi controller with an Arduino. But first, I want to test how I have to send the messages.
The amidi tool allows you to send arbitrary MIDI commands. For example:
amidi -l # find out what the port number is amidi -p hw:42,0 -S "C0 65 90 30 7F"
