Adde orchestral movie-composer-style REALTRACKS to BIAB to cater for film TV composers.
Currently they use HUGE orchestra sample libraries. Why not record real actual reltracks of orchestras and string sections recorded in pro-movie-recoding studios in hollywood ?

But at the same time an awful lot of media content is actually pretty predictable - falling into several easily spotted categories and "styles" that lend themselves to becoming "film-TV-composer" REALTRACKS.

A pro-composer could used such BIAB MOVIE-SCORING REALTRACKS as initial style-guides, to quickly put together prototype scores.
Used to submit to a director prior to getting a commission or commissioning a real studio orchestra.
To be able to quickly score an orchestral part without having to manually write out every part in MIDI would be a huge time -saver.

And as i already said most scored orchestral parts aren't actually that sophisticated arrangement wise - but just use simple triads.
Sure - Thomas Newman or Desplat **really** do know how to produce proper rich harmonically engaging orchestral arrangements - and get paid accordingly - but the sheer amount of output material is much much more dumbed down and this. And thus would lend itself to the use of BIAB MOVIE SCORING REALTRACKS!
