In the dark ..

Are there any ideas around making the text of the panel better readable in the dark?
Like fluorescence or modified buttons to light the text?
Some function are memorized after a while, but some I need to look up.

hmm. If it was fluorescent
I could.
A clip on reading light might serve you well
yeah, a light is an idea. --- The USB doenst give any voltage out right?
So I couldnt connect a usb led there? Would be ideal in portable mode.
For the more static usage I do use light anyway
Best.
I power my theoryboard no problem from deluges usb

I believe the USB port only powers external devices as long as the deluge is plugged in, which defeats your purpose (I could be wrong though).
So more of a diy idea. I'd love to see someone try this. Sound so stupid, but if it works...? 
A clip on reading lamp is the most elegant solution, I'd say.
Another solution would be to modify your unit and add a lamp with its own switch that connects to the internal battery.
Last one I can think of is to get power from the MIDI port: People in this forum have reported that they were able to use the MIDI to bluetooth adaptors which get their power from the MIDI port. Though honestly I wasn't able to find a MIDI powered reading light

If the enclosure was translucent, the LEDs would act as a backlight for the labels.
FYI - Oversynth has a new overlay for 4.0 available to USA ...
I figured I will give it a shot because I can't read the deluge font in my studio lighting. Just doing a quick visual comparison between the two images above, I don't see any major changes outside of the color.
That's because the images are still from V3, as it doesn't have the 'direction' text printed on them.
A laser cut acrylic case with silk screen printed labels would be rad!
I use an external power pack with a usb light. Totally portable, illuminates the Deluge really well and the one I use has 3 different colour temperatures and a very flexible neck.
The light was bought on Amazon and is the LEDGLE 3.4W USB LED Light Portable Reading Lamp.
And I have a desk lamp, bought it on Amazon...
