Hi, nice pad app, thanks! I find that most of the times that I hit the various controls at the bottom, it was accidental. (Tested on an iPhone) This kills the rhythm. The interuptions trained me to avoid the bottom of the pads, so the bottom row pads are effectively shorter than the top row. I never need those controls mid-drumming session anyway. Perhaps put the controls in a partially transparent "menu" button in a corner that is hold to activate. If it is tapped, it activates the pad its partially covering, (assuming thats what the drummer intended) but also changes to "hold" briefly, and fades back to normal. If its held for half a second or so, the menu is displayed. This would give the user the entire screen for drumming. Thanks for listening!
