Studio Rack looks like a great concept, but without support for 3rd party plugins I don’t see it as part of my workflow. Sorry.
I love the Waves plugins I own, but as most of us do, I have an investment in other plugs in that I also use in my workflow and there is not enough here to get me to replace everything in my DAW with new plugins.
I’d pay for a version of Studio Rack that allowed access to my current plugin library, but as it is now I don’t see the value, even with the 20 Waves plugins I own now. I would need to spend thousands more to use this effectively today.
