     Operation Manual 
Introduction 
Thank you for purchasing the ADVANCED INTEGRATION CONTROLLER CC121. If you are using Cubase, the CC121 
is a highly intuitive, indispensable aid in recording, editing and sound shaping.  Simply connect the CC121 to a com-
puter via USB, and you’ve got a comprehensive control center and seamless environment for complete music produc-
tion with Cubase. 
Please read the Operation Manual (this book) so that you can take full advantage of its superlative features and enjoy 
trouble-free operation for years to come. After reading this manual, please keep it available for future reference. 
Main Features 
Dedicated Remote Control for Cubase
 
The CC121 serves as a comprehensive control surface for Cubase (versions that are compatible with the Link func-
tion, such as Cubase 4.5 and Cubase AI 4.5; see page 15). Simply connect the CC121 to a computer via a USB cable 
and enjoy a hardware/software link specifically designed to give you tremendous efficiency and speed in your work-
flow within the Cubase environment. 
Smooth Parameter Control with the AI KNOB
 
The CC121 lets you mouse-over a desired parameter within Cubase, and adjust or control it by simply using the AI 
KNOB on the front panel. In addition, you can lock operation so that only one specific parameter is controlled—
regardless of where the mouse is located—by turning on the [LOCK] button. This gives you quick, constant, conve-
nient control over a desired parameter, no matter where you are in the Cubase environment. 
Intuitive Audio Editing and Transport
 
The VST Audio Channel Settings window (including EQ settings) and the Transport section of Cubase can be con-
trolled directly from the CC121. In addition, you can create automated mixing by using the touch-sensitive motorized 
fader and intuitively control the EQ parameters by using the knobs. Each of the panel buttons light or flash in the same 
color as that of the corresponding button on Cubase, meaning that you can confirm the current status of each function 
instantly. 
Assignable FUNCTION buttons
 
The FUNCTION [1] - [4] buttons on the front panel let you control various Cubase parameters, allowing you to assign 
desired parameters to each of these buttons. By using Cubase 4.5 or later (the latest version of the Cubase series), 
you can assign one of the two templates which include the settings for controlling the Control Room Mixer to these but-
tons. 
USB bus-powered
 
The CC121 can be powered by the USB connection to your computer. This means you can simply connect the CC121 
to a USB terminal on your computer, get full power, and not have to worry about setting up an AC adaptor. An AC 
adaptor has been included to provide motorized, touch-sensitive fader operation.

Turning the Power On and Off 
Power Supply 
To make the CC121 active, connect the CC121 to 
your computer via a USB cable so that the power 
can be supplied from the computer to the CC121. To 
activate the motorized touch-sensitive fader, youll 
need to also connect the AC power adaptor to the 
CC121 and a proper AC outlet. Instructions for these 
connections are given here. 
IMPORTANT 
Connecting the power adaptor to the CC121 and 
turning on the power does not supply the CC121 with 
necessary power; the power adaptor is merely an 
auxiliary power source for the motorized fader. 
1 
Make sure that the [STANDBY/ON] switch on 
the rear panel is in the STANDBY position.  
2 
Connect the USB TO HOST terminal on the

suspended) even if you do not operate the com-
puter for a long time. When connected in this con-
dition, the CC121 continues to draw power from 
the computer, even if you are not using it. Particu-
larly when the computer is under battery power, 
you should make sure to set the [STANDBY/ON] 
switch of the CC121 to STANDBY in order to save 
power and avoid draining the computer’s battery.
