Is the following possible.
When the switch is engaged, the volume block is enabled, but all other expression controls are disabled. When I hit the expression pedal switch, the volume block is disabled and control of all other parameters carries on as normal?
Essentially emulating two separate expression pedals with one.
when you say ‘all other XP controls/parameters’ carry on, which do you mean?
What else do you have it connected to?
(the switch can only toggle between 2 states, On and Off. You can invert the bypass state of some FX in the XP settings menu- those in an Inverted state will toggle ON when anything else toggles OFF. As long as you’re using the ‘Switch’ setting you can toggle between two states. It gets tricky if you have more than 2 fx assigned, but it can be done)
In the past on my old Helix, I would have two expression pedals.
One was just for volume, the other controlled.
Amp Gain/Volume/EQ, Delay/Modulation/Reverb parameters.
So I could go from a clean little effected tone to lead just by using the expression pedal.
I essentially wanted to replicate this with a single expression pedal and a switch.
I can only think of two work arounds.
a) Duplicate the signal chain, and switch between the two, one chain with no expression control, the other with expression control
b) Add an extra scene (Is expression control at the patch or at the scene layer?)
pretty much “A” is the only option available on the QC; the XP assignments are per preset- you can’t alter them per scene except for ‘bypass’ state.
