hi! I have a version v.3 of the resonators, and i would like to use attenuators on the single cv inputs like for the new version, so since they are normaled to the internal LFO what should i do with the LFO depth pot pads? can i replace it with a resistor between pin 1 & 2 and 3 to ground?
i'm trying to build a kind of Double Trouble, so also the x-panner is involved, but i would like to have single outs for the resonators using switched jacks before to go the 3 inputs jacks of the panner so this could give the option to run the single resonators outs to a delay or a reverb, before to go back to the panner....
does it sound doable??

no resistor. just solder a wire from pad '2' to '3'. pad '1' (GND) is not needed.

no problem at all. you just might want to solder a short protection resistors (330R to 1k) between the sngle outs of J8 and the jack sockets.

exactly. this will protect the opamps output. you might have seen those 1k resistors in other schematics as well.
