I'd have to say NO about the BiaB-VST.
I mainly upgraded to 2019 to move to the Audiophile version.
My workflow has been, Create in BiaB, Load into RB, Add more tracks, Export to DAW.
I thought the VST might make that faster & easier, but that's not happening yet.
I thought 64-bit would enable the use of better VSTi's. IDK yet, but we'll see.
I hope & expect to see improvements to the VST and to the program itself.
All that said, there really isn't anything else like BiaB.
