1) Could it be possible to have an autoload option while browsing drumsets.
2) You have an undo button, could you have a redo button too.
3) In drumpad mode, could you have a lock feature which locks a drumpad so the sound/sample on that pad cannot be changed.
eg. if I find a drumset with a good kick, snare, hi hat and open hat but want to change the rest of the kit, I could lock these sounds and continue browsing the drumsets.
It would also prevent changing the wrong sound by accident and not been able to remember the sample you were using. (I've mananged to do it a couple of times
