Biab Track Injector for REAPER should work under Linux as there is a Reaper version for Linux, and running Biab and AutoHotkey under wine.
The Reaper script just calls on Autohotkey scripts to access Biab functions.
The bb folder may have to be changed in the Reaper script to point to the wine folder as the script just needs to read C:\bb\Data
temp.text
trackdata.txt
RealTracksList.txt
RealDrumsList.txt

and the wine path added in front of the RealTrack/Drums path.

If the BBPlugin was self contained with all the functions in it rather than in the BB app it would work under Linux with yarbridge.

It would be good if there was a Biab Linux version but then they would need 6 months on Win, 6 months on Mac and 6 months on Linux and that is more months than in a year.
