Hi Thanks for the responses. I’ve tried setting the exp pedal to control input vol but that also kills all audio when in the heel down position.

As for using the left foot switch, yes this work but I was hoping to assign multiple hotknob parameters to the exp pedal to get more control, rather than just on/off. I also would rather not have to step on the H9 all the time! I could use an external foot switch but I still don’t get the variation from using the exp pedal.

One thought I had today was to split the signal and use both inputs, then in the delay have A set to permanently dry and B set up as the delay. I could then use a vol pedal on the 2nd output. Not sure if thus will work. Will need to experiment.

Thanks
