This video shows how to set up a Novation LaunchPAD to give LED feedback with Ableton Live. I send MIDI Clips to the LaunchPAD to activate the LEDs. I also show how the Launch function works to trigger the next clip in the arrangement.
IMPORTANT NOTE: The launchpad triggers MIDI Notes between C1 and B6, so when MIDI Notes are sent to the controller, the PAD which is assigned that note will light up.
