Totally doable.
BONUS #1: If you want the entirety of each path to be sent out separate outputs, select the Mixer block and set A Pan to "L100" and B Pan to "R100".
- Press MENU and then FS1 (Signal Flow).
- Turn the Big Knob to select any block and then turn Knob 2 (Path) to move it to parallel Path B.
- Turn the Big Knob to select the Split block and then turn Knob 1 (Move Block) to move it all the way left.
- Touch FS3 (Split Y) to display its parameters. Turn Knob 1 (BalnceA) to "L100" and Knob 2 (BalnceB) to "R100." This routes the L/MONO input to Path A and the RIGHT input to Path B. Both signals will be merged at the Mixer block at the end.
BONUS #2: Instead, if you want each path to be completely stereo, select the Mixer block, touch FS2, and turn Knob 2 (Path B Output) to "Send12." In this case, the Main L/R outputs are fed by Path A and the Send 1/2 outputs are fed by Path B, both in stereo. Yes, HX Effects could conceivably process two separate band members, each with their own input, stereo processing, and stereo outputs.
BONUS #3: If you want to quickly switch between two completely separate paths, select the Split block and change it to a Split > A/B. Assign the RoutTo parameter to a footswitch (or expression pedal if you want to blend between the two paths).
There's a reason we hide this kind of stuff in the Signal Flow menu.
Thank you!!!! This is one hell of an info post.
