I've tried em all ... this one is the best.
I really have tried the other drum apps. This one is the most fun. I love the variable attack. There are several tricks to make it work well: I prefer to play with the iPhone up-side-down so that the kick is on my right side, snare on the left, and toms decend from right to left ... just like a real kit (for right handed players). Per the instructions, it does help to turn the phone to airplane mode to reduce latency. I try to hit every instrument once before playing .. it's almost like the first time you strike each one, it has to call it up from memory, but after that the latency is nil. Set the iPod control on the home button double click. Launch the drums, then double click the home screen to control music. Put on some nice head phones, crank up the volume ... playing on top of tracks is a lot of fun! A previous commenter railed on tuning ... which he obviously prefers a heavily muted drum. Real drums sing.
