Not a true lightshow, but something cool nonetheless.
Besides the X/Y pad on the padKontrol, another cool feature is that each individual pad is configured by default to light up upon being pressed.
Did you know that you could make those pads light up by themselves?
All you need to do is configure your sequencer to send midi to the padKontrol’s midi in. Any messages it receives that are currently assigned to the pads will light up the respective pad.
Configure your sequencer, turn off the lights, hit play, and see just how difficult your drum parts are to play one-handed.
