I got my G2 about a week ago and I'm trying to recreate the Hordijk Twin Peak filter on the Nord Modular G2. It's basically two 18 db lowpass filters running in parallel that share a resonance knob. Instead of adding both of the signals together, it subtracts them and outputs the difference. However, this subtraction takes place before the signal is filtered. I think this is done by splitting the audio signal into two and inverting one of them. I'm still pretty new at using a Nord Modular, so any help would be greatly appreciated!
Below I have attached a diagram of both the TP filter and the differential amplifier.
