I still a bit confused on the button assignments for the MB-LC. Since it's a logic controller, most of these buttons should auto assign. http://www.ucapps.de/midibox_lc/midibox_lc_buttons.pdf specifies what the buttons should do, but what if I want them to do other things? Same with the faders and encoders? Will I just have to manually assign everything in Ableton? Just looking for a little clarification on the matter, thanks!
