Cgs synth

Hello,
Does anyone know if the CGS led boards could be made signal sensitive?
For example turning freq, res, cv in, vol ect. to 100% the led would be at its brightest and at 0% low or off without effecting the actual signal. I would like to have this option as well as the other options with the Led boards.
I know it's prob a dumb question with a simple answer.

Whats not to like about adding an led to everything?
Thanks,
Steve

Replace the pulldown 100k resistor with a 1N4148 diode (cathode to
transistor base). You may need to increase the value of the input (100k)
resistor. The value of the input resistor will depend on the hfe of the
individual transistor. You will never get it to track accurately down to
zero though, because the transistor needs 0.6 volts to turn on.
