the fastest and most useful sketchpad for pop music

Hands down the fastest and most useful sketchpad for pop music available. The simple combo of step sequencer, live keyboard entry to patterns (great with a click pattern going on drums) and the fantastic synths and useable default settings (even Init setting sounds great on the Hybrid synth) make this a joy to use.
I keep experimenting with other apps like Yamaha mobile music sequencer and others and keep coming back to this one for its ease of use and fantastic sound.
Thank you, icegear!
Only thing missing for me is patch preview in the list of presets.

Edit: Oh, and by the way this product rivals even Gadget! How? Ultra low latency. No waiting. You tap and sound is emitted right away. No lag.
