as a matter of fact
hit shift+program
hit drum 1-2-3-4 and press what ever pad you wanna change. once you've chosen the pad, now you scroll down and change the note. ya dig?
havent used a 2k for a minute , but what i always did was change the pads midi notes, saved the program as a template with no sounds on it, and everytime you need a new program...... load up the temp. program so you dont have to keep changing the midi notes!
