Hello,
Having some bare keyboards and raspberry-sortof boards, I'd be interested in
connecting both of them without using a midi interface, but only the available GPIO pins
available on the board. This is as well to save external components and as a programming
exercise.
After searching for information, nothing revelant was found, except a experimental python
script to read gpio and using the mididings library to output messages.
Is there a existing project which would scan rows/colums of a keyboard from the
designated(configured) gpios, and throw midi message to an alsa midi port ?
