There are a growing number of sample/sample loop players on the iPad. RGBSOUND Pro is another albeit a pretty one which could find it’s place on stage or in an art show. I also found it interesting how by stoping/starting clips the loops launch at different times creating some nice Minimal style “get in your head” sequences. There is a free version for a limited time. I like it.
“By tapping the colors you play sounds and you launch infinite electronic loops, by shaking the device you change your music pattern.” – rgbsound.com
