I was finally able to arrange a testing session with Tony, a very good drummer. We worked on my project for a few hours calibrating, changing, editing, stripping and simplifying my code. It was realised that I originally attempted to allow for too many drum sounds, and because of movement and sensitivity issues the output sound was poor, and contained errors. There is a massive difference between the video at the start of the day and the video from the end. The button nun-chuks works fine for the foot actions, but the general weight, shape, feeling and lack of tactile response results in a sore wrist after short periods of use.
