"DScratch is the first module made using Protein engine - it's a little audio manipulation software running on DS which ables you to play with an existing .wav file or recorded audio sample; you can pitch it, scratch it, rewind, mute and apply effects on it. Moreover, DScratch sends MIDI through wifi connection, which ables you to control external applications, like a VJing software as I do." - From the site Creators site http://gorgull.googlepages.com/home2 His demo (watch this if you are on the fence, its really good) http://www.youtube.com/watch?v=u6D1M_URBow I'm off to go try it out!!!
