I would not have both programs actively running like our new poster suggests, but would it work? I think it should work, but I don't use Reaper so I can't test it. However, I often record BIAB in real time into Adobe Audition.

You would load both programs, start Reaper recording, then start BIAB playing. To even attempt this, you will need to have a top-notch computer, probably running 64-bit Windows and more than 4 Gb of RAM. To minimize computer resources, I suggest freezing the BIAB tracks first. Also, set BIAB to use MME (which is really WDM) for its audio output so Reaper can use an ASIO driver while recording. You don't need to use the BIAB plugin mode, but it might make it easier to keep both programs on one screen.

4johnny, if you don't know how to do these things, write back and we will help.

Having said that, I concur with what Dan and Noel said is a better way to work.
