Would you like to explain step by step (without any references to other posts) what I have to do to get wav-tracks from Biab to Reaper easy way (of course drag and drop is one possible way) as you explained above. I would like to use always latest version of Biab (Audiophile) and Reaper and not use any old version concurrently with latest version of software. Sibelius is my most important enviroment enhanced by many contact libararies working with Reaper. Biab is nice to have for bacis band instrument on background.
