Great idea - I’ve been thinking about building out the right hand side for a while and wondered about racks (or at least more shelving); hadn’t thought about rack mount audio gear - thanks!
Regarding lighting the faders/power lights, I would do what I’ve done with the three boxes at top right (the ‘Laser Grid’); replace the LED’s and add them to the ‘Instrument Lights’ circuit, which is 12v PWM, hence variable brightness, effects etc.
This circuit also illuminates the gauges, main power switch and trap cave light, maintaining consistency across the whole system. At standby they sit at 10%, but when the system is active (IE; during trapping, compressor re-pressurisation, EPR filter purge etc), they come up to a nominal 100%, less system ‘load’ - so they fluctuate up/down depending on how much (virtual) ‘power’ is being drawn at any given time. (This effect is mirrored by the ‘Trap Operations’ illuminated buttons, again for consistency).
Additionally I’d add bright white LED’s inside the chassis’, behind cooling vents and add them to the ‘Panic Grid’, an effects only circuit that strobes during shutdown or power events.
Again, not all this is strictly necessary…
If you’re already familiar with the Pi and Python, I’d start by looking at the excellent gpiozero module: https://gpiozero.readthedocs.io
(Note that to get jitter-free PWM on all GPIO pins you’ll want to use the ‘pigpio’ pin factory rather than the default).
But don’t worry if none of this makes any sense, I can help you out!
