External Control
The External Control block is where external expression control is assigned to devices like the Source
Audio Dual Expression Pedal, Hot Hand 3 Wireless Controller, and expression devices connected to a
Neuro Hub. All external control expression devices connect to the CONTROL INPUT jack on the
topside of the pedal with a 1/8” TRRS cable.
• ON Button: Engages/disengages external control.
• Control Source: It is possible to control up to three parameters with external expression –
each of the three rows in the External Control block are assignable to a single parameter. Use
the Control Source dropdown menus to select the type of external controller being used.
There are three different options in this menu:
o Control Input X: Select this option when using an expression pedal or the X-axis of
the Hot Hand 3 Wireless Controller.
o Control Input Y: Select this option when using the Y-axis of the Hot Hand 3 Wireless
Controller.
o Expression (Hub/MIDI): Select this option when using an expression controller
connected to the EXP IN or SENSOR IN jacks on the Neuro Hub.
o OFF: Use this option to disengage expression control for the entire row.
• Control Option: Select from a long list of parameters available for expression control.
• Min (%) and Max (%): Sets the high and low points of each parameter receiving expression
messages. Setting Min (%) to 0 and Max (%) to 100 will assign the full breadth of the
parameter to the expression controller.
