At the recent 2007 NAMM Expo, a trade show for the music industry, Behringer was displaying a prototype of its popular B-Control BCF2000 USB/MIDI Controller in white:

There’s been no official announcement about the product, but it’s designed to match the white cases of Apple’s iMac line perfectly. Our sources told us that the company hoped to get the custom version of the B-Control into Apple stores.

The BFC2000 is an inexpensive but powerful USB/MIDI controller for use with music software such as Apple’s Logic. The production version of the B-Control is a charcoal gray color. For more info on the production version, check out Synthtopia’s B-Control review.

There’s no word on when, or even if, these will show up in Apple stores. Based on what we saw at the NAMM show, though, there are probably a lot of Mac-based musicians that would like to get their hands on one of these.
