After researching the app more closely, I can say that it is going to get a lot of folks into making music on their computer, folks who would not have thought to do that beforehand. I for one think that's ONLY a good thing. Ever since I got into the techno scene, I've envisioned music moving away from a creator/listener model, and more toward a form of two-way communication, where we kind of lose track of who originated what. This is a HUGE paradigm shift, but it is happening, and I think it's actually very good for our species. We may in fact be evolving, even if it's pretty much only mentally at this point. It's like when literacy started to become more commonplace (which is still going on in many places, of course) -- sure, the priest-class lost a lot of power, but it empowered people as a whole. I see this change in the way music is created and shared as being analogous.
