Midi

On the arduino I'm using the Arduino MIDI Lib to send and receive MIDI messages.

At the moment it's running over aruino's default USB-Serial with ttymidi to feed the messages into alsa. My version is slightly patched - the device strings for input and output are changed. If they are not the same mixxx thinks that are diffrent devices and doesn't send messages to the arduino.

I'm planning to flash the USB-chip on the Arduino to a HID-MIDI device with something like lufa or hiduino, but haven't yet decided which one to use.

The mixxx mapping files have to be copied or linked to /usr/[local]/share/mixxx/midi/ (mixxx <= 1.10) or /usr/[local]/share/mixxx/controllers/ (mixxx >= 1.11). I recently switched to mixxx-1.11 beta, but I don't use any new features of this version in the mapping, so they should work with 1.10, too.
