You will get 9 different drumkits and 13 loops to jam with. Just download and play.
Note: Of course a phone app cannot replace real drums. The reaction time and accuracy depend on the hardware of your device. So don''t complain about the software, when your cell sucks ;-).
Have fun playing...
... and PLAY WITH HEADPHONES! It will make a great difference.
Thankx for using, Spaceware <3 you!
