Picked one up today to help speed up step sequencing. Select scale mode on the launchpad pro, select your key and scale and then use it for note learn on the pyramids step sequencer. I know theory and my scales, but it is a faster and easier way to very very quickly program melodic loops.
I bought the old pro, which is heavily discounted at sweetwater, as I didn’t need the sequencing functions of the MK3.
Very happy with the combination right away. Next will be the blackbox to capture loops.
