This is a really simple experimental MIDI router implemented in Raspberry Pi.
The idea is simple: I have a synth that has the only MIDI-In over USB and lacking plain MIDI-In. At the same time I want to send external events to it.
To deal with that I use Raspberry Pi B and just translate all midi messages from USB keyboard to MIDI device.
Update FROM and TO in connect.sh and run the service. You can get those values by running aconnect -l.
To enable auto-start in Raspberry Pi checkout the repository to /usr/local/midirouter on your Pi, then run:
sudo ln -s /usr/local/midirouter/midirouter.service /etc/systemd/system
sudo systemctl enable midirouter
sudo systemctl start midirouter
Check if it started up correctly:
journalctl -u midirouter
You should see lines like this:
Feb 13 23:43:36 raspberrypi connect.sh[472]: + aconnect -l
Feb 13 23:43:36 raspberrypi connect.sh[472]: + sleep 1
Feb 13 23:43:37 raspberrypi connect.sh[472]: + true
Feb 13 23:43:37 raspberrypi connect.sh[472]: + grep -q Connecting To
Feb 13 23:43:37 raspberrypi connect.sh[472]: + aconnect -l
