Overview - Source Audio Gemini Chorus User Manual

The USB and Neuro ports transform the Gemini from a simple chorus pedal into a powerful multi-
effects unit. Using the free Neuro App (iOS / Android) or USB editor software (Mac / Windows), a
wide range of additional control parameters and effect types (phaser, flanger, resonator) are
accessible. When used together with the Neuro Hub, the Gemini is fully MIDI-controllable and 128
multi-pedal presets, or "scenes," can be saved for instant recall on the stage or in the studio. The
Gemini can also connect directly to a passive expression pedal or the Hot Hand for expressive control
of any parameter.
The Quick Start guide will help you with the basics. For more in-depth information about the Gemini
Chorus, move on to the following sections, starting with Connections.

Overview

Diverse Chorus Sounds – Choose from traditional chorus tones such as Dual, Classic, and Quad, or
delve deeper into unique sounds cooked up in the Source Audio lab.
Flexible Stereo Routing – The Gemini is equally at home in a mono rig or a stereo rig. A variety of
routing modes such as True Stereo, Mono, Mono-to-Stereo, Sum-to-Mono and External Loop allow
the Gemini to harness the true power of stereo signal chains.
Compact Design – The durable, anodized aluminum housing has a slim profile, a small footprint, and
sturdy hardware that will withstand the rigors of the road.

Universal Bypass – True bypass or buffered bypass? The choice is yours. The Gemini features high-
quality signal relays for true bypass and transparent buffers for analog bypass.
Preset Saving – Save your favorite sound by pressing and holding the footswitch. No need to
remember knob positions in the middle of a show.
Neuro Technology – The Neuro App opens up new possibilities for the Gemini, including completely
new effect types, additional control parameters, and access to the Neuro Community, including free
presets from artists and other users. The Neuro Hub can store up to 128 presets for the Gemini,
easily recalled with a MIDI controller. You can also download any effects for the Lunar Phaser or
Mercury Flanger and use them on the Gemini Chorus.
Deep Control Set – Beyond the four knobs on the face of the Gemini are many additional
parameters. The Neuro App and USB Editor provide access to the inner workings of the chorus effect
for advanced users who want to create a unique signature sound.
Parametric EQ and Low Cut – A 4-band parametric EQ is included in the Gemini, allowing for fine
tonal control, and a low cut filter tightens up the low end.
MIDI Control – All of the Gemini's parameters can be accessed and controlled using MIDI via the
Neuro Hub or USB. Class compliant USB-MIDI allows the Gemini to work as a plug-and-play device
with recording software running on Mac and Windows, and the MIDI Learn feature makes control
mapping simple. The Gemini can also sync to your DAW or other MIDI devices using MIDI clock.
