Did not know if this was the best section for this but... Looking for a relatively simple drum machine app for my iPhone. I browsed the app store and most of them seem to have a Hip Hop marketing slant. Does anyone use one that works well as a regular old drum machine? I want it to do a variety of styles, you know, some jazz, blues, country and rock. I am planning to use it more as a practice tool and am not trying to record some legacy album or anything. Any recommendations?
