If you are looking at this, then you already know that the Steinberg CC121 broke the mold with this control surface. Unfortunately they no longer have access to the materials needed to create these...so they were discontinued years ago and now they are highly in demand.
I recently partnered up with a facility that is built around Pro Tools...so I am unfortunately taking the leap away from my beloved Cubase and thus don't need to hold onto this awesome Control Surface.
Everything works as it should. I no longer have the original packaging, but everything is in pristine condition.
Here are some of the online descriptions of the Control Surface...
The Steinberg CC121 USB control surface lets you control your Cubase project effectively and efficiently, and it fits desktop recording setups perfectly!
The CC121 includes an extremely versatile Advanced Integration controller knob that can control Cubase 4 parameters, effects, or VST setting, as well as a single smooth motorized 100mm fader. Twelve dedicated rotary encoders and an array of useful buttons add functionality and control, allowing you to take command of your Cubase setup from a minimum of hardware space with the CC121.
