I use my cell phone camera for taking pics of wire configurations when I'm going to disassemble and for those 24 digit model numbers written in small font. As a close up camera it's great. I guess everything has a place.
This app looks a lot like another app called loopy which is a really successful app. I can see why Cake would be doing this. I don't think they will sacrifice X3 to develop/promote this. I'm hoping for more compatibility with Sonar in the future. A little Sonar that plays with the big Sonar. Like most other apps you can probably export what you do in this and load it into something else.
In the video I watched it looked as if the vocalist making use of it live was firing off samples that were somehow locked to a click. At least the drummer was in time with it.
