Then only reason I'm sharing this is that it's not well defined in the official manual and it drove me crazy trying to figure it out.
Changing CC# for sliders and buttons.
Edit > CC(button) > move the slider or button > Then Use Value Knob to change Value.
IMPORTANT > BEFORE pushing the STORE Button ...
Press Top of Value knob to set the change ***BEFORE*** Hitting the STORE Button!!!!!!
THEN: Press the STORE button
THEN Press the top of the VALUE Knob.
Great Keyboard controller but the worst manual I've ever seen.
