Digital Performer comes with a new plug-in called AudioTap. AudioTap allows you to route any Sound Manager compatible software directly into Digital Performer. In the Mac's "Sound" control panel (not "Monitors and Sound") you can choose "MAS" from the Sound Out section. When you set an audio track's input to "Sound Manager Apps," DP can record the audio of any program that uses Sound Manager for audio output such as BIAS Peak or Propellerhead's ReBirth.
