Novation Launch control XL - Knob lights

Hi, I bought Bome midi translator pro to translate the midi input from the novation launch control xl to a video editing software. The project is coming good but I am stuck with the led feedback. I can control the intensity and the colour of the button, but I can't control the knob light. I found in this forum the file that I attached here, it is intended for the APC mini, I tried it and some knobs leds switch on, but the project seems to complex to me to understand. Someone can explain me what I have to send to turn on a knob light (and the color) ?

Thank you in advantage

Hi,

The Launch Control XL MIDI LED map is quite different than that of the APC MINI.

The best way to control the LED’s would be to use the Sys Ex protocol that they define in their programming manual.

You may want to look around for an example on our forum for some other user. If you want I can provide an example on controlling a few LED’s.  The color map is different as well.

On the APC MINI example I provided, it is fairly complex and I used a bitmapping method to control LED’s.  For changes, I set the bitmap to the new values of the LED’s and then use timers to iterate through them and send LED display messages back to the controller to update their color.

Again, if you can give me an example of one or two buttons to push, which LED’s you want to control with them and what color, I could put together an example here on this board for free. If you want a complete project solution, then reach out to me in email with your detailed requirements and I can provide you an estimate.

The below example uses the first track focus button to alter the color  of the first knob LED.

There are two translators but only one enabled.

The first translator, when enabled uses standard MIDI note messages to alter the LED value (color).

The second translator, when enabled uses Sys Ex to alter the LED value (color).

Only enable one translator at a time.

The programming guide that I provided the link shows the Sys Ex format and LED color values. I documented the note numbers within the translator for note type of LED control.

Perfect! The note method is better for me (better to understand). My error was that if I open the launch control editor and show the label, I see that all the knob are control change (and there isn’t listed the note for the LED) so I used control change, and does’t work. thank you so much for your help!

Glad to help. Yes I found it odd that the note numbers were not documented in the manual. I found it on another forum web site. I guess someone had to trial and error to find the note numbers needed.
