Neuro Hub: This configures the Control Input port to receive MIDI code signals from the Neuro Hub,
allowing the pedal to be added to Hub Scenes (which are controlled by PC messages) and allowing for
MIDI CC (Continuous Controller) control.
Expression: Using the Source Audio Dual Expression pedal, or an expression pedal connected to the
Neuro Hub, it is possible to map up to three parameters to be controlled via expression.
Expression Control
Use a Source Audio Dual Expression pedal to control up to three different parameters on the Atlas
per preset. Parameters include Threshold level, Output Level, Tone, Ratio, Blend, Attack, Release,
and many more.
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 Atlas’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 Atlas to the
Neuro App or Neuro Desktop Editor. The Expression Control section is at the bottom of the Atlas’s
Sound Editor. Download the Neuro Desktop Editor and go to Devices > Show Offline Device Editor >
Atlas to view the full list of expressible parameters.
MIDI
The Atlas can also receive expression signal over MIDI. To do this, you need a MIDI controller that has
an expression input and is also compatible with the Atlas (this will be most MIDI controllers). Connect
your compatible expression pedal to your MIDI controller, and your MIDI controller to your Atlas via a
USB-MIDI Host. You can also achieve this with the Neuro Hub.
Using a Third-Party Expression Pedal
The Atlas’s Control Input uses a specific wiring to communicate with both the Dual Expression pedal
and the Neuro Hub. To use a third party expression pedal, please refer to the
One Series Third Party
Expression Pedal Guide .
