Here is as quick a demo I could throw together which still meets my minimum quality requirements.

Opening a BIAB .mgu/.sgu file in BIAB VST in Reaper should be a simple as it can get. So take a look at my setup and see if you notice anything different from yours.



BIAB – 2025, Reaper (current), i7-12700F Processor, 32GB DDR4-3200MHz RAM, Motu Audio Express 6x6 - My SoundCloud (Tip: No need to create a SC account to hear music - just hit ESC ).
