So I'm using an expression pedal through the PCB over midi to control a BigSky. What I'd like to do is have my heel down position be let's say 10% mix of the reverb and the toe down to be 50%. Is there a way to set a limitation like that to a specific patch? I use my set up for a fiddle and 10% is my normal "clean" sound, but when I play ballads I like to ramp it up into the 30-60% range depending on the song. I don't want to have 6 presents for different ballads with different reverb mixes. Any help would be appreciated.
