how to control LEDs on Novation Launch Control XL buttons ???
Does anyone know how to control the button LEDs (color and on/off) on Novation's Launch Control XL using Max?
I can control the button LED colors on the Launch Pad Pro just fine, but the Launch Control XL doesn't seem to function the same.
[I'm fine receiving data from the Launch Control XL ... and I've read the "Programmer's Reference", but I still cannot figure it out]
Thank you for any help you can provide!
The track focus and control button LEDs use ctlout messages and the knob LEDs use noteout messages. There's a great patch at the end of the article linked below that has the values you need. you'll need to add a control out for the button LEDs. it isn't in the provided patch.

Thank you @dwingus for the reply! I finally figured it out. All of the LEDs require noteout messages (knobs and buttons).
For factory setting 1: (MIDI channel 9)
You send the same noteout number (pitch) for each of the buttons that you used to received info ... but for the knobs I cannot figure out any good rhyme or reason for what they chose. The far left three knobs are 13 (top), 14 (middle), 15 (third down) ... the next three 29, 30, 31 ... next three 45, 46, 47 ... etc.
Hi Ben,
Can I be cheeky and ask for any tips on controlling LED’s on Launchpad Pro (as mentioned above).
I am new to all of this!
Many thanks
Roger
