I look at this thing as if its now a full fledged Kaoss Pad! Sound on sound, motion loopers, multi fx, recording...get the f@#% out of here! For something like $4?!?! If you use it with an interface like any of the ones he lists (I use an iO Dock) youre set.
This is the most cared for music app Ive maybe ever had. Consistent updates and quality sound. Having experienced the early days of this app its funny to compare to because it was always simple and still looks the similar but internally is basically unrecognizable and very capable. Truthfully the Koass Pad analogy is spot on, this may just be better bc its not $300, does the same things AND, with an interface, has better ins/outs! Very happy with this app.
