Hi James!
You certainly can but I wouldn’t recommend actually letting both of them process the audio in series. The result of double processing would probably be dense and unappealing.
If you have one of them on bypass, it will work fine, but that defeats the purpose of having both of them – unless you just want to use Breakaway’s Oscilloscope to see what Volume Logic’s output looks like!
Anyway, Volume Logic was the best I could do in 2002, and Breakaway is the best I can do NOW. I’ve learned a few things along the way, and Breakaway is significantly better in every aspect. I would recommend just uninstalling VL and using the latest and greatest.
