I'd advise against it: I know perhaps the "wireless" thing is nice on stage, but in the end a cable you can (usually anway!) rely on, while with bluetooth, I wouldn't be too sure. 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: http://arduino.cc/en/uploads/Tutorial/MIDI_bb.png Depending on if you interface has hardware MIDI I/O, B might be OK, and saves buying an Arduino Uno. That said, the simplicity of just plug & play USB MIDI anywhere is awesome! HTH, -Harry PS: I have python script to read serial data using the "PySerial" module, and turn that into ALSA MIDI somewhere... leftovers from a similar project :) That allows using the Decimilia as a USB MIDI device, so long as the python script is running. Note that its obviously not ideal: with Python being rubbish for speed, and its a very non-portable solution since the Py-ALSA-MIDI / PySerial modules aren't common.

One of the "features" for professional audio production that is currently missing is a way to use a bluetooth controller with JACK transport. AFAIK no one has taken on that job yet. I am very interested to hear if you make any progress with that. It should be possible to route the signals from PA through to an OSC or MIDI controller or maybe we just need a plugin for bridging directly between PA and JACK. -- Patrick Shirkey Boost Hardware Ltd
