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.

the GEM library extends PD into video manipulation, enabling video inputs, which can be analyzed with [pix_multiblob] or other [pix_]. if you have the extended packages loaded, you should be able to simply type 'pd -lib Gem' from the command line, if you're using linux or mac. With the image you have attached I might suggest checking out arse.sourceforge.net. It's still very early in development, but it converts audio into spectral images in bmp format, and converts back.

hack it up!
