Going from the Exp out on the pedal to the Exp 1 in on the QC did you assign the Exp 1 input to a Wah block in your preset? The Hotone pedal Wah will not work through the Exp 1 input. It you want to use the Wah in the Hotone you need to run a standard TS cable from the Hotone Out to Input 1 or 2 on the QC like you would to an amp.
Looks like you can run both at the same time but the switch on the Hotone cannot control the Exp function only the Wah.
I’d be tempted to use the SP as a stand alone wah along with the expression pedal but I don’t see a way to decouple the wah and expression pedal function on the SP. For instance if you have tne exp out assign to control the gain on an amp when you turn on the SP wah it would still be contolling that gain too.
Digging out this thread…so, there is no way that the Hotone SoulPress II’s foot switch controls the Exp2 to activate/deactivate blocks?
When I try to calibrate it, it just goes to 100% all the time.
That means your switch is working. You just need to go to a block, and then it’s settings menu, and to “assign expression pedal”.
You can follow the rest from below video. It’s possible to assign any block by switch, or turn on/off by expression pedal position etc. many many possibilities.
