Digidesign hasn't built expansion cards specifically for Sound Manager 3.0. Apple's release of Sound Manager version 3.0 allowed third-party companies, like Digidesign, to build expansion cards for sound input and output, rather than having sound go in and out of the internal mic or Mac speaker.
Most Macintosh applications that make any sound do so by using Apple's Sound Manager. The Digidesign Control Panel requires Mac OS 9.0 thru 9.2.2.ĭigidesign Sound Drivers is a System extension that allows any application that can play sound via Sound Manager to play that audio through Digidesign hardware. (If using Pro Tools III hardware, install and use the Digidesign Sound Drivers extension.)
