You are missing the point completely, All Modern DAW's have no problem at all with non destructive audio editing and play direct from source.
If Biab had this you would not have this problem, you could simply copy any section of a RealTrack to another track without it becoming a wav file, you can apply any effect without it becoming a wav on the hard drive.
If it played direct from the source as DAWs do, it would be quicker and you would have a Live Arranger that played real audio not midi direct from keyboard chord input.
And that is a BAD thing ?
The best thing you could possibly do is contact all these DAW companies and get them to go back to destructive off line editing of the 90's.
Last year utility tracks generated up Audio RealTracks this year they are in RAM, does that get a bit scary for you ? How can you stop PG going any further and allowing copying of RealTracks to another track without it turning into a wav file and having more non destructive editing like Vol automation, where did that come from ??? I was the one that had to really fight to get Vol automation in RealBand !!!! I was the one that showed way back how to have more tracks in Biab !!! I have showed PG how to have instant generate of tracks in RealBand !!!
Way way back I suggested Biab be 64bit and have more tracks, I copped so much flack for suggesting such a thing !!!
And now I see the same users saying how wonderful more tracks and 64bit are.
So many things that have been added to Biab I suggested that you yourself now use, and here I am now getting hassled for saying such things.
I think you should be showing a bit more appreciation for what I do rather than purposefully giving me a hard time. I use Reaper as an example, if it can do it Biab can also.
Maybe you are one of the reasons here why Biab was still stuck in the 90's for so long. Why don't you suggest new ideas yourself rather than fighting to keep it in the past, if you want that go back to an older version.
It's like you are holding onto the past and don't want to let it go.
Give me a *^%$&( break and grow up.
