I finally grabbed all my small screen casts i made of synthmate as i developed it. It begins with the original concept, inspired by and using Matt Gemmell's multi-touch demo (http://mattgemmell.com/2010/05/09/ipad-multi-touch/). It then moves on to the control panels and initial look and feel. Later, there are some different visual ideas i played with before arriving at the final look. Enjoy.
