Control Input

The 

CTRL (control) input supports different methods of remotely controlling the pedal:

•  Expression pedal
•  Control voltage (CV) with 0-3.3V range
•  Tap Tempo
•  TRS MIDI in (tip active)
•  Remote switch

To configure a expression pedal or remote switch, hold down the right footswitch while plugging it in.  
The pedal will detect which device is connected using the steps below.  You can also use our web editor 
to configure the port.

The configuration is remembered when power is turned off.  Expression pedal assignments and remote 
switch settings are stored in presets and remembered when power is turned off.

Expression Pedal

An expression pedal can be assigned to any combination of knob settings at the heel and toe position (up 
to 6 parameters).  Moving the expression pedal will morph between the settings.

You can also calibrate the range of the expression pedal, to ensure that its full travel is used.

Calibrating Expression Pedal Range (no knob assignments):
1.  Start with the pedal powered on and nothing plugged into the 

CTRL port.

2.  Hold the right footswitch while plugging in the expression pedal.  The right LED will blink yellow 

three times to indicate it is in 

CTRL configuration mode.  You can release the right footswitch and 

begin configuration immediately.

3.  Move the expression pedal to the heel down position.
4.  Move the expression pedal to the toe down position.
5.  Hold the right footswitch for 3 seconds to save the configuration.  The right LED will blink green to 

indicate that the configuration has been saved.

Configuring Expression Pedal Knob Assignments
1.  Start with the pedal powered on and nothing plugged into the 

CTRL port.

2.  Hold the right footswitch while plugging in the expression pedal.  The right LED will blink yellow 3 

times to indicate it is in 

CTRL configuration mode.  You can release the right footswitch and begin 

configuration immediately.

3.  Move the expression pedal to the heel down position.
4.  Adjust the knobs for the desired sound.
5.  Move the expression pedal to the toe down position.
6.  Adjust the knobs for the desired sound.
7.  Hold the right footswitch for 3 seconds to save the configuration.  The right LED will blink green to 

indicate that the configuration has been saved.

Knobs that are not adjusted during configuration will not be affected by the expression pedal.  Expres-
sion pedal assignments are stored in presets and when the expression pedal is unplugged or power is 
turned off.   Expression pedals with 5-25 kΩ linear potentiometers work best.
