Control Knobs 
All of the knobs on the pedal are shown graphically in the pedal parameter editor. For pedals with an 
option knob (a single knob that controls multiple parameters), all of those parameters are shown as 
separate knobs in this interface for easy access. 
In order to change a knob, click on the knob and drag your mouse up or down. 
ON/OFF Status 
Click this button to engage or disengage (bypass) the pedal’s effect. 
Control Input 
The control input drop-down menus allow you to select an external control input and assign it to a 
modulation parameter. 
The first drop-down menu selects either the Hot Hand or an external Expression pedal as the control 
input. The second drop-down menu selects which parameter that control input will modify. Each pedal 
has a different list of parameters which can be externally controlled. 
Save and Close 
Saves the changes to the pedal in the scene and returns to the main Hub Manager window.
