If I drag the RealBand temp files into Reaper they are all in mono. So Reaper is just loading the source flac sections as written in the frozen Biab SGU.
The only reason I do all this with Reaper is it lets me script whatever I want, if I had the RB source Delphi and could program it I would do it now for you and upload it, whatever you want, believe me I'm not trying to force you to use Reaper. If I could do the same with Studio One, MixBus Ardour I would. I used Adobe Audition for all my mixing, I loved it but I could not program it to integrate with Biab. I had to venture out of my safe zone and try new things, that's how new ideas and innovations come around. You need to take some risks to tackle the fear of the unknown, with that grows understanding.
I made up an AutoHotKey script for someone with a laptop that could not scroll, I spent time and effort with it to help but they said they were too old to double click to run a script but had no problem using Biab.
