Anyone use the Steinberg CMC-FD?

The video demos, including the Steinberg one, have a finger rapidly moving up and down to show that it works. Okay, right. But done of them show haw smoothly and evenly it works when, for example doing a smooth fade out or level move. Nice job guys. Anyone out there actually own on and can chime it. Does it work as smoothly as a motorized fader like on the Faderport?

There is an entire sub forum devoted to questions about CMC devices. This issue has been covered numerous times.

Some people say yes, some people say no. I say no. YMWV (Your milaege WILL vary).
