"I find it really strange that a program that has been around for this long has got so many problems.
Nevertheless, -I like the concept of BIAB and there are simply nothing like it on the market but the issues I have experienced should have been taken care of before release. A program like this should inspire and not make the user frustrated and loose inspiration.
PG should offer a Demo version !
"

I think that nailed it, my sentiments exactly.
They have started now on the 2017 version, so that gives them 6 months to reprogram a solid C++ version, if there is not a profound change for 2017 that is it for me, Hasta la vista, baby.
If so I will get into scripting in Reaper and create a script users can use and share instrument/drum tracks they have recorded/created and Reaper reads the BWF chord markers & Acid tempo within the wav file (created in Reaper's render dialog from the track makers) and then fits them to your Reaper's chord/marker track.
Having very large forum with so many users there would be a large community input of tracks and further script development.
