And with non destructive editing, if you copy or cut a section it won't create a new wav file to build the size of the SEQ up, it will just reference the original wav file start and end points in the wav, this way the section I cut can be resized out to the same size if need be by dragging the ends. If I copy the track 100 times the SEQ file folder will still be the same size there won't be any extra files created.

If you want new users to come to RB then I think this is a good idea to modernize it. These are things that put me off using it rather than another DAW.
The Instant Gen/Play that I talk about in the BiabVST Plugin can also be done in RealBand especially !!
RealBand will tell bbw2 hey I need these chords for this RT,
it will randomly choose the chord sections from the RT files,
but rather than then generating those sections to RAM then rendering them to more wavs it just tells RB what section to playback direct from the source RT files. The RT files don't need to be copied to the SEQ folder as they are a permanent location reference.

Sure, it would need a re-write to compete with modern DAWs, but what needs to be done to RB that will make you use it more ???
