This module is very similar to HetrickCV's Flip Pan. It pans two input signals by flipping their channels (i.e. the left input is panned right, the right input is panned left). This sounds simple, but it is very versatile.
-Plug one signal in and monitor both outputs to use this as a traditional panner. -Plug two signals in and monitor only one output to use this as a crossfader. -Plug one signal in and monitor the opposite output to use this as a VCA.
