I'm surprised that people are using the Arduino devices for MIDI. Has
no one been able to get the full resolution out of the Analog In pins?
For the simple switches, I don't see it being a problem, but I'd
rather have more than 128 numbers for continuous controllers. Has
anyone had success with that? (I suppose we're no longer talking about
Linux audio.)

I'll suggest two options:
A) Get a Arduino Uno (so you have the flashable USB chip), and make it
appear as a class compliant USB MIDI device. ALSA will pick it up, and
automatically list it as a MIDI I/O device. Done.
B) Use a hardware MIDI output from the Arduino: setting the serial
baudrate
to 31250 (midi baud rate), and writing the bytes you want using
Serial.write() does the job. The hardware MIDI output is very simple:

Hi, there's a third option, use the VUSB software USB emulation with a
simple AVR chip. I used this SW to build a simple MIDI I/O device that works
fine with Linux:

There are already some projects using my MIDI code:
