In DSE's book on V4, there's a screen shot which appears to be an original-looking VU meter, perhaps even dial controls. It may have replaced the bar/slider mixer control. Any idea where one could get that? Any other good place to find plug-ins?
If you are referring to Vegas 4 Editing Workshop, that book came with a CD and all the software and plug-in demos are on it. The PSP Vintage Meter was the one in the book. (check the CD)
If you want to find great plug-ins, KVRAudio.com should be your first stop. (I spent a week there one night) ;-)
For some FREE, high-quality VST audio plug-ins try The Classic Series from Kjaerhus Audio. These are really nice.
