For proper operation, the configuration steps in the next section must be followed when using any
expression pedal, whether from a third party or from Source Audio.
Configuring the Expression Pedal
When the expression pedal is connected to the True Spring, follow these simple steps to calibrate it
and map it to control different effect parameters. Note: you can also map and set the range and
direction of external expression controllers with the Neuro Mobile App or Desktop Editor.
1. Press the CONTROL INPUT button to turn on Control Input mode. The Control LED should be
lit green.
2. Press and hold the CONTROL INPUT button until the Control LED begins to blink slowly
(approximately one blink per second).
3. Move the expression pedal over the range of motion you would like to use to control the
True Spring. If you would like to use the expression pedal's full range of motion, then make
sure to move the pedal all the way from its minimum position to its maximum position.
"Dead zones" can be created, at the top and bottom of the treadle sweep, by only moving
the expression pedal over a limited region of its full range of motion.
4. After setting the expression pedal range, click the True Spring's footswitch once. The
calibration is now complete, and the Control LED will blink faster (about 2 blinks per second).
Now, it is time to map the expression pedal to the effect parameters.
5. Move the knob(s) you wish to control with the expression pedal to the minimum desired
position(s), then click the True Spring's footswitch. The Control LED will now blink even
faster (about 4 blinks per second). Up to three knobs can be controlled simultaneously.
6. Move the knob(s) you wish to control with the expression pedal to their maximum desired
position(s), then click the footswitch. The Control LED will now be lit solid green. The
mapping is complete.
Note: The parameter range can be inverted by swapping the minimum and maximum position of the
knobs during calibration.
Hot Hand Input
The Hot Hand 3 Wireless Effects Controller can be connected directly to the True Spring's Control
Input for motion control of the True Spring's effects parameters. Visit the
Source Audio website for more details on HH. The Hot Hand has two axes of expression: X and Y.
These signal are carried on the two rings of the TRRS cable that comes from the Hot Hand receiver.
