I really like the Sound Stage concept. Rather than a smaller version, I’d have been interested in a version that integrates with a mixer. Building a mixing solution around Sound Stage proved difficult for my use case of using it in a fairly traditional way to mix different parts of a song together in a spectrally balanced way. It does that pretty well, but it introduce enough ambiguity about what parts should go where and how to add effects and what not.
That said, if you’re tempted by either this new one or the original, give it a swing! The concept works really well.
