This patch is set up to play 16 single midi notes C4 to D#5 that correspond to the 16 pads in sEGments. This allows you to play up to all 16 pads on the app sEGments by Elliott Garage, with the Tonality Pads. It is also setup to quickly midi learn each pad to an external midi controller. That makes this patch a good workaround for easily midi mapping and playing the sEGments app on your external Midi Pads/Keys/Controllers
