I love my 57 and it sucks because i love it so much when i gig out with some people i dont bring my 57 because i would rather no one else touch it lol, and i get withdrawals from it..... Anyways i use the 57 to do everything and when im scrolling through the tracks i use the expand feature to have a much bigger view. I sort my tracks by bpm and i was wondering if there is a page up page down feature that i am missing where i can skip 20 songs at a time instead of spinning the knob a million times (Im afraid im going to wear out the knobs pre maturely). And it would make it much easier :).
