Hi
I think many of the perceived problems folks find in RB or working in multiple programs in general.
Is that at some stage after importing you are going to need to save, at this point you need to make your mind up where you are going next.
All daws including RB have a native format that will save the whole project as it is and retain for further editing by that program . in RB it is a. SEQ file in Cakewalk it is a cakewalk project file .CWP.

Lett’s say you have a BIAB song that you then open in RB
If you save say a RB editing session as a BIAB file it will not save all the info,unless you save it as a SEQ.
There is no magic bullet like always converting to midi as midi does not itself support many things found in DAWs like Chord data.

So what I am trying to say is once you find a work flow that carries along in a logical sequence to you, from one piece of software to the other don’t try and go backwards
Or you will likely lose something on the way.

I might also say there is a lot of difference between opening and importing and saving, saving as, and exporting, when working in multiple software.
Just my thoughts
Mike
