I thought it was about time I tried the BIAB VST3i plugin on Reaper. I'm using a RealTrack style (_STREET).

The "Send To Reaper" seems to do what I expect, but Drap and Drop is doing something quite odd. I've tried a few things, including RTFS.Most, but it seems consistently inconsistent as follows.

I generate the tracks in the plugin. The time it takes to do this varies and the generated tracks are sometimes vey full and sometimes quite sparse. I've often seleceted each track and done "generate entire track", which generally seems to give a full regeneration. However the oddities go further. If I use the Drag and Drop option to copy tracks to Reaper, sometimes it offers the options including "replace content" and sometimes it just pastes the track adding to the existing content. When it does this, it seems always(?) to paste a sparse content and always to paste a stereo track, despite the track itlsef being mono.

As so often I've spent too long on this already and not enough time practicing, so for the moment I'm just leaving that report as it is. If anyone wants to try replicating it.

I got the update in Decempber and this is the first time I've actually tried to use it for anything, partly as I'm so rarely in Windows, partly because I increasingly resent spending hours trying to find out why so many things behave oddly. BIAB is wearing me down.
