Mario, You are amazing at helping people here, and I know we are on the same page on this.

However OP and other two members vividly proved the point I was trying to convey. Instead of using common sense critique, or even reading my proposal in wishlist (I am not even talking about supporting it), talk continues about liking the software and "how difficult" it would be doing this and that, or "finding" other "methods" that are not remotely close to something that a user would expect in 2026.

Ok Jonel here goes. BIAB, from the conception used a similar approach as with all other arrangers that "followed" chords. MIDI styles. That was / is the heart of BIAB. That was 30+ years ago... The engine to handle MIDI the way it does is in place. Not being able to import, export, audition, edit these proper way is nonsense. It has nothing to do with DAW. These are basic arranger functions. As far as I know, most physical arranger keyboards and modules from 90s, even some $99 ones allowed to modify import/export/copy/edit style parts. In a second quarter of 21st century this should not be even asked for.


Having said that, BIAB's new UI was a major step forward, so as a few other big features that were done in the past few years. That shows, contrary to some (conservative) remarks and pushbacks that BIAB can be transformed to a significantly better software. I can complete 65-80% of the tune now in BIAB compared to about 40% about 4 years ago. The time is ripe do things that relate to user experience, items as original OP post for example, among with about two-three dozen of other highly requested workflow enchantments. Reducing unneeded complexities to minimum.
