SA242 Gemini Chorus User’s Guide 29
After the Gemini receives its first MIDI clock message, the function of the Speed Knob changes.
Instead of controlling the speed of the LFO directly, it controls the number of subdivisions are in the
LFO, using the MIDI clock as a basis for the tempo. One, two, three, or four subdivisions can be
created. Musically speaking, this means that the LFO can run at the rate of quarter notes, eighth
notes, triplets, or sixteenth notes. The following diagram shows the knob positions corresponding to
each subdivision, with the knob currently set to quarter notes:
The number of subdivisions can also be modified via MIDI using the Speed parameter. If you have
mapped a MIDI CC message to the Speed parameter, you can choose the number of subdivisions
using the following table:
MIDI CC Speed

The Gemini does not sync to MIDI timecode containing SMPTE timestamps.
USB
The Gemini’s USB port is plug-and-play ready for Windows and Mac computers. The Gemini uses
class-compliant drivers, so no special drivers are needed. Just power up the Gemini and connect it to
the computer using a USB cable. The computer should automatically recognize the Gemini, which will
be identified as “Source Audio One Series” in the operating system.
USB-MIDI
The Gemini will appear as a MIDI device in your computer’s operating system. As a result, the Gemini
can communicate with audio production software that utilizes MIDI, such as Pro Tools, Ableton Live,
Logic Pro, and more. MIDI messages can be sent directly to the Gemini using the USB connection,
which allows for full automation of the Gemini within host software such as a DAW. For example, the
depth or speed of the LFO can be automated by outputting MIDI continuous controller messages
from the host software to the Gemini via the USB connection.
Envelope Mode
The Gemini can be set up in a slow envelope or fast envelope mode
