Hmm, so you're saying that the device sends keyboard events. How did you find out which kind of data it sends out? Sending out midi note events is easy with RTMidi, check out the section on midi out section. It contains a section on MIDI note output. I don't have much experience on grabbing keyboard type events using a daemon. I would recommend finding a cross platform solution. If not try finding out how to read keyboard events while being a daemon. Like a keylogger I guess. C++ isn't much of a jump from C so it should be easy to pick up and go.

Being that the little I know is C, is it much more difficult outputting notes using the alsa api? alsa midi device. uhm, i'm not sure... the driver (snd_usb_caiaq) actually takes care of the soundcard built in the pedal, and on the way also makes the buttons create keyboard events, and the pedal EV_ABS
