Does anyone know of any good Drum Machines on the iPhone? I could use Beatmaker but I was wondering if there is anything with a more intuitive UI for just drums only. I would need it to make a beat, be able to edit the beat, and it have a tempo change. This would mainly be used for metal-type music to be played along with, but one for all genre's of music would be helpful as well. Sorry if this is posted in the wrong area (probably is) but I thought I would ask. Edit: Don't give a damn about the price either.
