As a long time user, I find this thread depressing. For me BIAB has always been like the latest Ferrari.. with many parts held together by string.
I tried loading Spectrasonics Keyscape as a VST, and found it doesn't work (again), like many of my other VSTs. I wrote to PG and got no reply.
After over a decade of use, I do NOT expect things to work, I still find the whole program obscure and unreliable. At least PG has finally struggled onto the 64 bit about a decade after other DAWS. I never have problems loading VSTs in ANY other program, just this one. I have never succeeded in using my keyboard VST sounds "within" BIAB so that I can actually record as I play along. I find things crash, the set up is obscure and the GUI for VSTs is weird and ad hoc. Tracing MIDI channels though the maze is very tedious and MIDI channel is NOT listed in the mixer, which is basic to any DAW.

My favorites are also continually disappearing (for a decade) for no apparent reason, so I never use these too.

Many of the windows like preferences and midi set up have a Windows 95 feel and are obscure and badly need reorganising

So many things need redesigning. The latest update 625 has fixed a few things, but there are loads more issues that have been around for years

So, all I ever do is load a song and hit play or type in a few chords. Even there, when I loop, it's not visually represented on the chord screen - e have no way of "seeing" the loop. It's just another poorly implemented feature I have got used to.
I skipped 2018, and won't buy 2020 unless there is some big positive changes reported by experienced users.
