Cool App I found for the iPhone/iPod Touch called TouchOSC. It’s basically a touchscreen midi controller that uses wifi as a connection. It’s idea and presentation is similar to a Jazzmutant Lemur which go for like 3k or something stupid like that. So the TouchOSC is affordable option though not sure how well it would really work out in the live setting or really recording because it is so small. None the less looks flashy.
