No you can’t change the leds, the color or brightness. I use color tape to give me a quick visual of what track I’m using. Especially the tracks in the middle. It can get confusing, so beware of that. I love using the Launchcontrol XL personally and it’s opened up the OT for me in completely new ways. Now I can’t live without it. The knobs and faders work fantastic. The knods are not continuous but I only stay in 1 page. CALC from Novation wrote the user map on for the LCXL and he did a great job. He has a youtube demo of it. The interface I use between the Launchcontrol and OT is an iconnectmidi 4 and it works perfectly. The iconnectmidi has a great advantage because it’s a midi merger, router and thru box. I can merge a midi keyboard and Launchcontrol xl to control the OT. You should definitely look into that combo. If you really need to configure your leds then maybe a launchpad pro, Livid or Keith McMillan midi controller. I not totally sure on other options.
