If you don't have Nodebeat, now's the time to grab it. And you should. This is one of my personal favourite apps for coming up with quick unique and interesting beats/melodies, which I then AudioCopy/Paste over into Samplr and iKaossilator. Works like a charm.
It's free (as is Nodebeat HD for iPad.) Grab it.
Get it on the App Store for (currently) free.
