ALSA: snd-usb-caiaq: Add support for Maschine
William Light [Mon, 10 Oct 2011 15:54:23 +0000 (15:54 +0000)]
This adds partial support for the Maschine controller by Native Instruments.
Supported now are the 1x1 MIDI interface and the 41 buttons, 11 endless
rotary encoders, and 16 pressure-sensitive drum pads. Still to work on are the
dimmable LEDs and the two monochrome screens.
