Expression pedal w/ reverb minimum

[jo_fi]

Hi, I was wondering if there was a way to set up an expression pedal to control the mix of a mercuryx where the toe is 100% wet and the heel is just whatever the initial mix is in the mercuryx preset. I was to be able to ramp it to max but not have to guess where I was before ramping it up. Would the best way be just to somehow set the minimum cc value to correspond to whatever the mercury preset mix is and do that for each preset? Or is there a way it can figure that out itself?
Thanks!

The PBC doesn't have any information about what's going on in the Mercury X, and doesn't have any way to find out, unfortunately. So, setting presets up with specific levels as you mention above is the only way. You can set up an expression pedal override in each preset that has the desired range.
