A Nashville producer told me
"Myself, I find the user interface to BIAB one of the most confounding, and downright biggest UI messes ever, but that's just me. But... that is a great program in terms of what it can do and those real tracks they use now, sound more realistic than anything anyone has going. It really is fantastic."
mind you this was a long time ago and there have been many improvements such as ideas from VT's video implemented, but yes it's time for a more professional GUI.
With all the tracks in there now maybe more like a DAW or at least have some modular layouts that the user can move the elements around and save as a layout along with the skins.
It's just that a lot of the old 8.3 255 limitations are still there.
The more I type the more Déjà vu there is, "haven't I been here before ?"
