Just tested the Bias pot, this works too. although the range is smaller
but this can work as a coarse & fine setting.
The range of the pots is indeed small With the LDR’s , you can use the remaining ‘dead’ range to fade in from white or black. This works great!
and tested CV input with a hacky vactrol. WORKS!
cv input: LFO. the vactrol is not super fast. it can do some audiorate modulation though. horizontal scrolling bars were visible.
1v video signal: I need to change the led resistor to see if this works
I tested the Gain pot, with a yellow (clear) led & 1k resistor + LDR and some electrical tape.
