Greetings!

Buttons are brighter with the lights off. Part of the hijack patch for button illumination includes an automatic sensor - if the headlights are on (as registered by the empeg) the brightness factor of the LEDs (as measured by the hijack setting) is cut in half!!! This is not configurable from any known menu or configuration, but is hard coded into the kernel...

I have always meant to post a wish list item about making that configurable somehow...

Edit: This is the way it is supposed to behave. With the headlights on, it is assumed it is dark / night out, and you want to dim the LEDs accordingly. Unfortunately, the brightness is not controlled by the dimmer percentage mechanism through software, but via hardware, so the player and the LEDs do not share matching dimmer configurations.
