No, BB/RB is the only Audio program that has this problem, other midi/audio DAWs don't have this problem, Audition 3 has midi and it still works in that, Reaper has midi and it still works in that.
Audition/EZD2 is just an example how VSTHost can save the day, nothing to do with BB problems.
Just try them, download VSTHSS Legree and try it.

So if vst problem fixed maybe it can save the day for BB.
If it gets fix you can add more tracks to BB with wav player VSTs also.
