Never heard of it, thanks for the info.
But no matter how good it may be, it won't become a standard until many DAWs adopt it. And then you need the big players in the plugin world to offer it.
When you see Waves offering AAX, VST, AU, and CLAP, then it will be a standard. Plus it will give them a reason to charge for another WUP upgrade
Like Waves or not, they are the biggest player in the pro plugin world.
Time will tell.
