Now to get more users from the DAW world a simple thing you can do is have a FREE version of the DAW Plugin that handles Loops only.
This seems to work fine with these minimal files,
BBPlugin\Files\vst's
Data\ library files
Preferences
RealTracks\Loops
bbw4_32.exe
bbw4_64.exe

If you just grey out the menus in the Plugin and just have Loops only available.
Where the Logo is you can have ads promoting RealTracks, RealDrums, Artists etc.. if you upgrade.

Also in the Loops picker where you have optional
"If you want a different sound for the ‘b’ substyle, enter that WAV file name in the "b substyle loop" setting."

You can have Endings with:
"If you want a one shot loop for the ending, enter that WAV file name in the "Ending loop" setting.
Or an A or B Ending loop option.
