I didn’t so much like the wet/dry pot in the module. It resembled more a feedback option in practice. So I changed that and changed the gain factors of the op-amps (U1A and U1B) as well. Because one is inverting and the other isn’t they can be used to partly cancel each other’s effect out, but because of the wide range of the gain factor you can choose the cancellation point and measure of cancellation along the I-V curve of the LEDs. The amount of variation one can achieve in this way combined with adding the dry signal and switching the LEDs is quite large. Yep, this is a keeper!
One more change, I swapped the output elco for a non polar capacitor because the signal at the output of the opamp can have a negative or positive DC offset.
Note: I left out the attenuation pot at the CV-input. This was because I didn’t have enough space on my panel. You can of course leave that in if you like. I will make a passive or active multi with attenuation in the future, so that function will be implemented elsewhere.
