Since many people don't know where to start when composing microtonal music, I put up a short tutorial on how to get microtonal playback using either and AXiS-49 keyboard or your QWERTY keyboard and some freely available software, with a few examples at the end of different scale structures and chord progressions that are only possible in microtonal music:
