Drum Kick [Final Animation]

Please watch the full animation here: http://goo.gl/6XgXC

A drum kick generator I'm working on. Two kicks to blend, four effects to mix and two independent parameters (decay and tone) from each kick. The circles around the main one will be the step sequencer. A show/hide step sequencer is also included to have more precision on the iphone.

Trying to have a much more digital approach and get advantage of all the features multitouch screens can handle instead of going with knobs and faders.

Your feedback is much appreciated.
Thanks for watching.
