“See the sound. Hear the visuals.”
The CG-8 is the world’s first instrument that lets you “perform images” in real time.
This leaflet will explain the basic concepts of the CG-8 in just five minutes.
These are pictures (JPEG images) with an effect
(movement) applied.
These are pictures (PNG logos) with an effect
(movement) applied.
Press the [PHOTO PATCH] pad,
then press one of the number pads
that are lit.
The Photo Patch background is combined
with the Stamp Patch foreground.
First, hold down the [PHOTO PATCH] pad and press
the desired bank (one of the number pads that are lit).
Then, press one of the number pads that are lit; the
bank and patch will change.
* If you want to switch Stamp Patches,
press [STAMP PATCH].* Press [STAMP PATCH] if you want to switch Stamp Patches.
Press [PICTURE] if you want to switch Pictures.
Press [EFFECT] if you want to switch Effects.
The patch in the video output will change,
and the display panel will indicate the patch
number you selected.
Switching Pictures
Press the [PICTURE] pad, then press
one of the number pads that are lit.
The picture in the video output will change,
and the display panel will indicate the

XY pad
D Beam
Internal mic
The CG-8 can detect peaks in the audio input from its internal mic or the rear
panel LINE IN jacks, and use these peaks to control the image.
Press the [INPUT SELECT] button to select the audio source you’ll use.
Move your finger left/right (the X-axis) or up/down (the Y-axis) on the
XY pad to apply an effect to the video output.
Move your hand above the D Beam sensor to apply an effect to the
video output.

Holds the effect even when you take your finger away from
the XY pad

Lights when a peak is detected
Lights in response to the input audio
Lights when the input level is excessive
Adjust the input level so that [PEAK] lights briefly
at the loudest sounds.
Turn the [INPUT LEVEL] knob to adjust the input level.
Turn the [PEAK FREQ] knob to specify the range at which the CG-8
will detect peaks.
Adjusts the depth of a speed-related
effect parameter.
12 o’clock is the center value.
Turn toward the right for positive change.
Turn toward the left for negative change.
Adjusts the fade.
Turn toward the right for
fade-to-white.
Turn toward the left for
fade-to-black.

processed by the effects are
output in real time.
Adjust the depth of X-axis, Y-axis,

Toward LOW: Detect low-frequency peaks such as bass drum
Toward HIGH:Detect high-frequency peaks such as cymbals
As an exception, turning the knob all the way to
LOW will detect the power of the sound rather
than a specific frequency.
