From Waves site: StudioRack lets you run up to 8 plugins on just one insert, save chain presets, open them on any DAW...
I have a number of Waves plugins, and saw this free offer on their site. Basically allows to build FX chains with their plugs and save them all with the various settings/presets you might be using for use in the future.
Is this just an FX chain "shell" like the one already in Sonar?
