[Alsa-user] Using a USB serial device as a MIDI source

[Bill Purvis]

I'm currently working on an Arduino-based project which generates MIDI
output.
Under Linux it appears as a /dev/ttyUSB?. How can I persuade ALSA to
treat it as a MIDI
source (and possibly destination).

Your hardware should correctly implement the USB MIDI protocol in the
first place.

Anyway, you could try a tool like ttyMIDI.

Hi Bill,

i've tried this for a simple Arduino based MIDI pedal (ttyMIDI wasn't
available at the time). If you're running JACK this could be an
alternative:

https://raw.githubusercontent.com/7890/jack_tools/master/example-clients/tty.c

using this library for Arduino:

I don't know how tty.c differs from ttyMIDI, you have to try what fits
best your case.

Greetings
