I think BIAB has created a lot of valuable REALTRACK, but it has not been really used well. There are hundreds of GB of RT content on the hard drive, but it cannot be quickly found and flexibly used. This is a sad story.
I agree with you 100%! Many forum members have requested better search tools.
One request I made some time ago (that was pretty much ignored) was for PGM to curate the vast collection of RealStyles into sets that play nicely together in a song to give it some dynamics without sounding like a completely different song just started! The A and B sections is a nice option but often it changes very little. And, before someone jumps in and starts promoting multistyles, there are far too few of these to properly resolve this issue.
1) RealTrack = recorded bits of a specific instrument
2) RealStyle = professionally curated collection of RealTracks that sound good together
3) RealSong = professionally curated collection of RealStyles that sound good together and provide dynamics/variety
#1 and #2 exist and are fantastic! How about adding #3 as well? It helps BIAB users AND provides something else for PGM to sell!
I have to add that, while I really truly appreciate when expert users offer work-arounds, these are often complex or require installing additional programs so they often do not provide resolution to the reported issue for regular users.
