Steinberg has released the latest Cubase SX update, 1.03 which fixes some serious bugs (mainly audio dropout and Midi timing issues), but also adds support for the new Mackie Control board (a clone of the Logic Control also made by Mackie).

Here is the link to the PC Update Page:

This is great news! The Mackie Control looks just awesome, and is a hot contender to Steinberg's Houston.
