I think this is a mighty clever app; I'm not really sure why there are so many negative comments.

It would be nice if the url changed with the sample combinations though. It looks like you can record a chunk of the sound and share that, but I'm far more interested in sharing the exact combination that I come up with than I am the sound itself. I'd love to just send a link to a friend so that they could not only see the combination in action but also dive in and make it their own.
