Quick Preset Mode
Allows preset mode to be enabled/disabled in 0.8 seconds instead of 5 seconds (by holding down the
footswitch).
Neuro Hub (Formerly the Soundblox Hub)
The Source Audio Neuro Hub (sold separately), unites Source Audio pedals from the Soundblox 2 and
One Series families to create a single, stage-ready system. It features shared MIDI, passive expression
pedal input, Hot Hand connectivity, and USB, and can connect to up to five Source Audio pedals. The
Neuro Hub features a powerful scene saving functionality, which allows you to create up to 128
multi-pedal presets known as scenes, each recallable via MIDI program change messages. Connect
the Neuro Hub to your computer via USB for updates, saving and editing multi-pedal presets, and
more. To connect the Gemini to the Neuro hub, use a 3.5 mm TRRS cable and make a connection
between the Gemini’s Control Input jack and any of the Neuro Hub’s multi-function outputs. For
more information, refer to the Neuro Hub documentation on the Source Audio website.
MIDI
Using a USB connection or the Neuro Hub (sold separately), the Gemini can be controlled by generic
MIDI messages. Each of the Gemini’s parameters (even those that are not assigned to a control knob)
is directly accessible via MIDI continuous controller messages. MIDI messages can be sent directly via
USB or forwarded on to the Gemini via the Neuro Hub.

MIDI Continuous Control messages
In order to assign a MIDI continuous controller to one of the four knobs, the effect selector switch, or
the enable/bypass footswitch, follow these steps:
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. Send a MIDI continuous control message to the Gemini via USB or the Neuro Hub. When a
valid continuous control message is received, the Control LED will begin to blink faster
(about two blinks per second).
4. To assign this continuous controller to a knob, turn the corresponding knob. To assign it to
the enable/bypass footswitch, press the footswitch. To assign it to the effect type switch,
toggle the effect type switch.
5. Once the MIDI continuous controller has been assigned, the Control LED will be solid green.
This shows that the mapping was successful. Note: The Control LED blinks any time a MIDI
message is received, so it’s possible that the Control LED will continue blinking even after
the MIDI mapping is complete – this shows that MIDI messages are still being sent to the
Gemini.
For parameters like depth and speed, which are normally controlled by knobs, the full range of
continuous control values from 0 to 127 will be mapped to the range of the knob.
