Wouldn't it be more universally compatible to have a powered knob that outputs a adjustable constant control voltage? You'd probably want trim adjustments on it too.

Yes, there'd be an extra wire to the power supply module, but that seems fine for a modular.

Maybe other's modular synths look/work differently than mine, but when all the panels are installed, there is no way to pull a cable from underneath the panels/inside the case to the outside, without drilling new holes through some panel or the sides of the case. So not sure how you'd pull a cable from the power supply to the front side of a panel when it's closed like that. My case is a Intellijel Palette 104HP, maybe other cases expose the power supply to the outside?

Yes, but there are already many of these in modular form (usually attenuators normalled to +5V in the absence of input voltage or just fader modules without inputs). This is new :)
