This is a sneak preview of Quickswitch, a new controller described as "the world's first turntable controller."
Here's what Quickswitch designers have to say about it:
Quickswitch allows users to control any software without having to touch the computer. Quickswitch allows users to perform normally impossible tricks with lightning fast speed and accuracy. Quickswitch turns your computer to an engine running in the background, and allows you to focus on your instrument. This video shows the original prototype version & extension modules. The final production version is now ready for market.
Pricing and availability are to be announced.
