Why not changing the colour of the frame but keep the font in white for all kinds of status.
Good thinking. Let me give it a try, see how it looks...
I have a small problem with the playback buttons switching off by holding them for more than 1 second. And the space for the desklight is lost space. What about 4 buttons in this space for switching off cues like "bank on top of screen off", "all banks on top of screen off", "bank on top of faders off" and "all banks on top of faders off"?
I won't argue the functionality of the desklight with, because there isn't

We just found it a cool idea to fill up that empty space. Sure, if we find anything anything usefull to put in the desklight's place then it's gotta go.... we'll work in the 'dark'! Let me have a think about an easy way to release the playbacks, maybe we can think of something systematic... 4 buttons for roughly the same function feels a bit 'expensive' to me, however, a get the your point: it would be great to make 'releasing' faster.
Is it possible to connect to different controllers. e.g. a BCF 2000 and a Nano pad and put the same funktion on both controllers? Like blinders on a fader on the BCF and on a pad on the nano?
Cuelux is set only to listen to one midi controller, so if you want to use two controllers it becomes difficult, but not impossible.
What you would need is one midi controller with a MIDI input that can merge the incoming MIDI stream into its own, eg. the BCF2000 or use a software tool like midiyoke. Then you would need to create your own midimap file. You would need a basic understanding of XML to create a new file that combines for instance the BCF mapping of that of the Korg nanopad. Just keep your new file in the 'midimaps' directory and Cuelux will load it next time. This 'midimaps' folder is difficult to acces on Mac Os, I'll move it to the user directory in the next release to make things easier.
Is it possible to use a playback button with a controller which is on a bank that is not selected on the screen - like bank 1 on the screen and controller controlls bank 2?
No, unfortunately this is not posibble; the banks on the screen and midi are sync'd.
