At the moment i 'm working on an installation, to generate sound out of an ink dripp, falling down on a perspex plate (vertical/gravity). Does gem got a tutorial about video tracking and any additional information to get me started on this visual/audio experiment? And does anyone can give me ideas on the issue of converting visuals to midi?

thanx

The attachment shows an example of my artwork. the goal is to generating in real time sound during the creation of an visual artwork.
