Lighting LEDs Using SysEx Messages
$
It is possible to control Launchpad MK2’s LEDs using SysEx messages. This allows a number of
LEDs to be updated quickly with one message. The index of the LED is taken to be the same as
Session layout, regardless of the layout Launchpad MK2 is currently in, with the top 8 round
buttons indexed as 68h to 6Fh (104 – 111).
