The Movement I-V is an iPad app that explores the various possible movements of the hand and the fingers in sound manipulation. Included are a set of sounds by me (some of them are used on the upcoming Alog album, set for release in early November. The album use this app as one sound source). You can also upload your own samples in .wav or .aif format through iTunes. 

Here is a link to the app page on iTunes

The development of the Movement I-V was supported by Arts Council Norway and BEK, Bergen center for electronic art
