Anyone on the list know how to persuade an Arduino to look like a MIDI
device?
I've got it generating MIDI signals via a MIDI breakout unit, but want
to connect direct
to my PC using the USB. I've got it sending what appear to be valid MIDI
messages to
/dev/ttyUSB1, but qjackctl doesn't see it as a midi device so it can't
connect it.
Any useful information would be welcome.
Thanks in advance
Bill

There is code for doing that with the Uno onwards, but it reprograms the USB
module itself, which means that afterwards you can only reprogram the processor
via the 6 pin connector and a proper programmer.
Try here for a start.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

Arduino by default enumerates its USB port as a virtual serial line (that's why
your device is named /dev/tty*). In order to automatically enumerate its USB
port as MIDI, you need a board with a processor that features an on-chip USB
controller so it can be reprogrammed to also enumerate as USB MIDI [1].
Alternatively, for Arduinos without on-chip USB, you can simply send your MIDI
via the virtual serial line and run a ttyMIDI daemon on your receiving host
which will mediate between serial line and ALSA MIDI [2].

Thanks, Hanspeter! Two useful links there.
I tried searching on the arduino forum, but got fed up after seven pages
of completely
unrelated messages.
ttymidi looks really useful, and works with my current code. I haven't
plucked up
courage to try MIDIUSB as it messes with the setting of the USB
bootloader and
I haven't figured out how I'd get out of it if it then decides to refuse
further
uploads. Maybe it's OK, but I'll postpone that for now. I can always run
several
copies of ttymidi when I get round to adding further complications to
the project.

Yes, look it up om the arduino forums.
I couple of quick URLs from my arduino tab:
http://vusb.wikidot.com/start
https://github.com/adafruit/Adafruit_ProTrinket_Bootloader
Or use a Teensy - http://www.pjrc.com/teensy/
or - http://www.pjrc.com/teensy/td_midi.html
I'm using one in a midi to 1V/oct analog synth driver that I hacked together.
