Hey, so I’m trying to use a Roland EV-5 expression pedal to adjust parameters of presets, but no matter what I’ve tried it only adjusts the volume. I’ve gone in and tried adjusting the knobs via heel down toe down while it is set to both calib on and off and still nothing but control over volume. Is there something simple I’m missing that needs to be truned on or off in order to engage the expression pedal to be a controller for other parameters?
