Thanks for your help. I solved it by using different ASIO devices for Reaper and Band in a Box. however I also tried opening the BIAB files in RealBand and then using this Daw Plugin mode which I think might be a better way to do it. The files are already generated in RealBand so dragging them to Reaper is instantaneous. It also solved the problem that I was getting individual files as stereo (eg bass) which I wanted as mono when I went from BIAB to Reaper. However when generating the BIAB song in RealBand they all generated correctly as mono apart from drums in stereo which was correct. There seem to be many features in RealBand which make it a very good intermediate step before transferring to Reaper.
