RE; VST and VST3 And AU HOSTS ...,

Although I have never tried it in band in a Box. I just want to mention Blue Cat Audio's Patchwork (plugin)

It hosts VSTs Vstis (including VST3 ) and AU I use it in live standalone mode also without needing to open a DAW for hosting V.I's and the plug in chains of my choice .

The bonus here is that favorites can be saved and can me recalled via a midi switching pedal
