Already sick of playing the piano on your iPhone? Maybe it’s time to hit the drums.
Drummer can play up to 15 unique audio samples (one on each finger touch pad), and takes advantage of multi-touch capabilities, so you can play up to five sounds at once. You can even let your MP3s play in the background and provide your own accompaniment. There are pre-installed Rock, Dance, Electro and two Jazz sound sets, but can be easily updated with your own sound samples.
The application is currently in private Beta, so you won’t be able to get your hands on a copy for your jailbroken iPhone quite yet. In the mean time, you can read more over on MooCowMusic.
