Monome as keyboard for Supercollider

I would like to use the monome as a simple keyboard input to Supercollider, where each key corresponds to a single pitch. They would be laid out like a guitar fretboard: Rising chromatically along the rows, and by some bigger interval (say 5 halfsteps) along the columns.

Has this been done?

not exactly that, but the SC tutorial should show the way quite well:

Stretta’s “fourths” does a similar thing, not sure it was made for supercollider though
