Hello,
BIAB 2018

which is the best way to pass the BIAB tracks to reaper?

I do so:

in BIAB I create the tracks using Realtracks.
I save the song to biab format.
in Realband I read the song created with BIAB.
in Realband for each track I right click on each track and from the menu I choose track-> save track to file (WAV)
I open Reaper and I import the WAV tracks

Any better ideas?
