almost everything works in the traditional way except that I use the "loop out" button as my shift key (modifier) to control all functions on decks C & D (leds are already mapped, so you can have visual help on every deck), also I've mapped the "loop in" button to activate the loop function controlling loop size with "- pitch bend +" buttons... If there is any error please lt me know so I can fix it... feel free to use it & customize it as you wish (beware with the MIDI notes on LEDS because are not the same MIDI notes than buttons...) I use grup fx & make no changes on it
