Hello, I'm thinking of buying a Helix and wondering if this is possible. I would like to run the main outputs in stereo to one power amp and a stereo output from of the FX sends to another power amp. Both outputs on all of the time but controllable via an expression pedal where toe down is signal to one amp, toe up is signal sent to the other amp and midway the signal goes to both amps. Thanks in advance, David
