The Fader flip option is a really slick way to set up your aux levels quickly using the motorized faders.

MotorMix functions as a stand alone controller or as an 8 channel expansion unit for Dashboard or MotorMate.

Here is a review of MotorMix:

MotorMix is the most compact unit of its kind that I have seen, with motorized faders. CM Labs seems acutely aware of the variety of studio situations in which this product is bound to be used. MotorMix conserves physical space, yet the layout is roomy and comfortable. In addition, multiple MotorMix controllers can be mechanically connected into a single "linear" package or with "wedge" inserts (available from CMLABS.net) to form an arc. Some of the 56 back-lit switches are labeled, while others are strictly user-defined, and all can be applied to a variety of mixer, transport and plug-in functions. The first thing you'll notice about MotorMix is its rock-solid feel. From the full-throw 100mm faders to the 40-column by two-row alphanumeric display, the unit feels totally pro with no "flexing" of any kind when a switch is pressed. A quick peek under the hood reveals high-quality Fiberglas-epoxy circuit boards with plenty of support. This is not a disposable product but one that can grow with your needs. 

CM Labs also makes "Dashboard", a dedicated transport controller with a large jog/shuttle wheel. MotorMix connects to your workstation via MIDI in and out ports. (There is also a 9-pin accessory connector.) Some workstations support multiple MotorMix units — Pro Tools accepts up to four. Workstation manufacturers are responsible for supplying the appropriate drivers. For example, Console Manager is the Soundscape applet that allows users to select MotorMix from a list of supported controllers. Within Soundscape's Settings menu is a user option to boot Console Manager along with the workstation. Once this is done the first time, simply select "Save Settings," and it becomes transparent.

The unit I tested was running Version 1.08 firmware with Version 2.0 of the operator's manual. Firmware can be updated in the field. While the manual focuses on the Pro Tools interface, MotorMix can be used with a variety of workstations, including Minnetonka's stereo and 5.1 surround software. Working on my Soundscape system, I got right to work on a mix from scratch, and it sure was great to be able to put down the mouse and simply audition individual tracks. All of my onscreen track labels showed up in MotorMix's LCD above each channel strip. MotorMix can only display four characters for each channel. Thus, I modified some of the onscreen track descriptions to make the most of what could be displayed on the LCD. At the upper left corner of the controller is a pair of View buttons that advance channel access to either the next bank of eight or the next group of four, depending on which of those switches is selected. To take full advantage of the 100mm faders and of Soundscape's automation, some global levels are set onscreen. For example, "overdriven" electric guitars can be recorded hot, resulting in fader positions 20 dB down from nominal. Automation systems do not have as much resolution in this area; trimming the track's level down 20 dB allowed the fader to "live" at nominal. From this point, I made all fader and mute moves from MotorMix, including lead vocal composites. MotorMix always responded with speed and precision.
