15 years ago RealBand should of been Reaper Track Injector as I would not be here now half dead from it all.
I know they have said they have big plans for RealBand but I just have a felling they will go off half cocked with it.
Whereas with Track Injector for Reaper you get instant tracks in a quality DAW.
The main issue users have with Track Injector you have to hack into the menu and use AutoHotkey to get what you need. If Biab had track data text file Reaper would read that direct and get the tracks even faster without having to get Biab to write the track data for 1 track it will already have the track data for all current tracks as C:\bb\Data\BBoutput.txt.

This could not possibly cause any problems but sell more Biab or Audiophiles packages to Reaper users, and how many Reaper users are there compared to Biab or other DAW's users ??. Long term Biab users will still be able to render down to consolidated wav files and drag into their DAW but those that want total instant creative control will use Reaper direct.
