Spent some time seeing if the BIAB-VST would follow a Tempo map in Reaper. Picture tell the setup. You can see where I Ritardendo a full bar section to drap out the part. Then return to original tempo. Works and sound great in Reaper, but no so much with the BIAB-VST. My conclusion is it does not follow the song tempo map when played in Sync mode.

However if I copy and bring the midi / RTs over I suspect it will work fine.
