Here is a heads up from Music Radar http://www.musicradar.com/news/tech/free-rg-muted-plugin-from-rob-papen-only-with-computer-music-185-566931
 
As well as getting the mag at a news stand, If you follow the links it looks like you can but a single online edition of the magazine for 2.49 UK pounds which now includes down loads of most of the stuff on the DVD. I am not sure if the version currently on sale is the one with the Rob Papen plug in however.
