You can set the EXP jack on NightSky to accept an expression pedal for real-time control over any one or more of the knobs in any direction.
To set the EXP jack to Expression mode:
NOTE: EXP jack assignment persists through power cycles.
To assign knobs to be controlled with the expression pedal:
Make sure to save your presets after assigning the expression pedal to save the assignment to your presets. We recommend using an expression pedal with a 25k Ohm minimum potentiometer.
NOTE: Expression pedal assignment is saved independently per Favorite/MIDI preset.
