Another all in one script that should get Biab drums into Reaper in Linux
**Not sure how accurate the wma files will be in Linux if Reaper is using ffmpeg rather than Windows Media Codec.
I don't think you will have wmf as an option
"Just set Reaper Prefs > Media > Video to use wmf for wma as priority, the latest version of Reaper my set that as defafult any way
wmf ffmpeg vlc qt:mov,qt,m4v,mp4 dshow:!mov,!mp4,!m4v,!qt"
