Do you have any suggestions of afordable external control surfaces?
SONY says that... "External Control Surface Support and Fader Automation
Take advantage of hands-on mixing using external control surfaces with Vegas 5 software. Receive and send commands to compatible outboard devices to control transport, faders, mutes, solos, pans, effects automation and video tracks. Vegas ships with built-in support for the Mackie® Control Universal, but the generic control interface option allows user-customizable mapping of MIDI control commands to your favorite control surface".
