QLab is an excellent tool for building playlists for walk-in and walk-out music. I go as far as sending a MIDI command from QLab to my Avid Venue to recall a snapshot that mutes all inputs except my playback channels. At the end of an event, simply highlight the cue group in QLab, press ‘GO’ on the Q-Widget, and everything fires. fohDave (Dave Staghl) over at goingto11.com writes about his experience using Qlab to setup playlists for walk-out music. In his case, he fires his QLab playlist from an Avid Venue snapshot, presumably via MIDI.
