Demo
Normally the cool stuff is here so I can catch your curiosity. Video / YT incoming ?
Introduction
Transform your old computer’s parts (and not only) into midi instrument. list of features
Technical Part
For me, the cool stuff is here
Interfacing with DAWs (Reaper / linux ATM)
Serial Arduinos (mini pro, micro)
plug the arduino and verify with dmesg to which device it is mapped map with midi2serial/usb with ttymidi -s /dev/ttyUSB0 -b 115200 -v check all the instruments with aconnect -l map 2 of them (reaper out ttymidi in) with aconnect 129:0 128:1 for instance
USB Arduinos (due)
connect the board to native usb port. reaper should see the arduino as midi device directly
