The presentation, the sounds, and the idea is nice, but by the latency (delay) can be on tap unfortunately no rhythms. At least no normal fast. The application has probably not much for it, it is likely to provide hardware (in my Nexus 7) and Android itself. What would have been nice would be a loop recording mode with metronome. Where to for example 16 bars can type from the front with an additional track easily again. Presumably, however, would also here the latency make the fun a spanner in the works. Everything a shame because the app would have been like for all nervous finger drummers me a real asset.
