Noel, Mario Thank you for pointing RB.
I will be truthful. I do not like RB.

I think it made sense when DAWs were expensive and here you get 2 for the price of one...Sure is a deal.
Now, with all the wealth of DAWs available for free or at very fair price, I find it a bit painful
making myself re-learn something that might or might not survive in not distant future. There is no
substitute for BIAB. I put my prejudice aside, and no matter how some things are annoying me, I will still be
using it just because it will do good things for me smile

I can avoid RB partial-regeneration feature by simply gather audio-files and learn how to work fast with multiple audio files in DAW of choice. Time wise it would be very comparable.

Regardless of my ventures, it would be nice if BIAB had the feature of freezing/regenerating sections. As Dan noted, it was asked for years... I definitely support that request, but if the sections could be dealt with independently, it would be an icing on the cake.
