Biab has made a big leap this year but for those that want more:
I Think the problem with the stuff I post is it's so far ahead and down the track to give way more control of creativity, from where most users are now BUT will be there in the future.
This is why I spent so much time and effort with Reaper showing how Biab and the BBPlugin can work way better.
All this stuff can NOW be done in Reaper so professionally, instantly and easily with the BBPlugin ver 6
or if you only use Biab Open SGU in Reaper will instantly transfer tracks to Reaper and update any sections anywhere.
Allowing over 255 bar limit.
Fit to any varying tempo map.
You can have so many Tabs with projects in and copy from one to the other.
You can create up so many different project Tabs using your chords in so many different Styles instantly, no hours of rendering and dragging.
Being able to name the RT RD track sections that you can see where instruments change.
Being able to write the chord names to the track sections.
Being able to instantly change from FX <> Direct Input keeping the same riffs.
Convert a Stereo drum track into Stems instantly.
Having Video RealTrack/Drums.
You know what, I think I can even load a VST3 in Reaper.
I don't have to wait years for things that might be implemented as I can look in Reapack for a script, ask in the forum for one or make one myself and it's done that very day.

It could take years for the penny to drop or it can happen today !
