Did you ever get this working? I'm using an Akai mini to control Dashlight, works good, but just like you there's no light on the buttons of the Akai controller.
Is there a way or program that i can use to control te button color en light?
Go to Input > Midi Note Options and play around with the values till you get something lit up on the controller... I have the same problems with the launchpad i run.
