The point to me is that while these programs are very similar each one has some unique qualities that work better than the other.

Clearly the biggest advantage of RB for me is being able to add various Real Tracks or midi track at measures I want and being able to easily delete any parts of tracks I don't want in the final mix.

However BIAB is much easier in being able to change keys in parts of the song; making copies of measures; add an intro to a song ect.

Right now I do my intial work in BIAB... import to RB where I add various instruments... mix it down and then import it into Sonar where I do my vocals and final mix...

The process is not overly time consuming but for me, it seems it makes sense to combine the best of both programs...for example making the chord view in RB essentially BIAB with all its bells and whistles... and then the track view becomes the driving engine for RB....I think that would make everyone happy and an easier work flow...that's all I'm saying
