This workspace will fail if iTunes is not set to open in local music library. If it ttys to connect to the store or has an update pending, you need to clear that so that the script can run.
It Starts by opening iTunes and then asking you for a level for iTunes and setting that. It will track the adjustments you make to the iTunes level, and return to that level whenusing the duck and restore cues.
Both the Duck and restore cues are on Hot Keys of Shift+D and Shift+R respectivly.
The workspace plays the iTunes Playlist "walkin"
I hope this helps - I didn't really get a chance to look at it again too closely. I also haven't tested it in anything greater than os10.8.5 or QLab 2.3.9. Please let me know how it works out for you.
