Expression Control
Use a Source Audio Dual Expression pedal to control up to four different parameters on the EQ2 per
preset. Parameters include Band Frequency value, Band Level, Band Q value, Master Volume
(Output) Control, Noise Gate Enable, and Limiter Enable.
Common uses for the Expression pedal would be to map it to Output control so the EQ2 + Expression
pedal would act as a volume pedal, or to automate the sweep and bandwidth of some mid-range
frequencies to simulate a “wah” effect.
Connecting the Expression Pedal
Connect a Source Audio Dual Expression pedal using a 3.5mm TRRS cable from the EXP pedal’s
Sensor Output to the EQ2’s CONTROL INPUT port on the pedal’s top panel. Press the CONTROL
INPUT button to enable External Control.
If you are not getting the desired results from your Expression pedal setup, go to the Hardware
Options section of the Neuro software. You’ll need to select “Neuro Hub/Expression” under “Control
Input Option”, and you may also need to calibrate your expression pedal. For more details, visit
Hardware Options.
Mapping Parameters
The quickest way to map parameters to your expression pedal is by connecting your EQ2 to the
Neuro App or Neuro Desktop Editor. The Expression Control section is at the bottom of the EQ2’s
Sound Editor. Download the Neuro Desktop Editor and go to Devices > Show Offline Device Editor >
EQ2 to view the full list of expressible parameters.
MIDI
The EQ2 can also receive expression signal over MIDI. To do this, you would need a MIDI controller
that has an expression input and is also compatible with the EQ2 (This will be most MIDI controllers).
Connect your compatible expression pedal to your MIDI controller, and your MIDI controller to your
EQ2. You can also achieve this with the Neuro Hub.
