With Pipewire thing, and after I've set up a bunch of keyboards in my office, I was thinking about trying to find a setup for playing live. Over the years I've just used Mainstage, but I don't see why I can't use linux. 

Last time I checked there wasn't really anything in this space to do this, but  I was thinking that there might be all the pieces to pull this together. Basically something that could manage midi sources and push them to plugins and do some basic mixing. I would think that Pipewire, WirePlumber, Juice, and Calf plugins would be able to do most of the heavy lifting, and a Juice project to manage the GUI and session data would get me there? Anyone have any advice for this?
