Yes I have regenerated the song. It messed up my chords that I liked (that's why I froze them). frown
Freezing tracks will stop all changes to those tracks, even chord changes - in general we recommend only freezing as the last step of creating your song. You may need to unfreeze all the tracks then regenerate to make things work properly.

Interesting. If possible can you email the song file to support@pgmusic.com so we can take a look? Freeze the tracks first, and let us know which bar number it happens at.

The octave down on the second F9 is likely normal behaviour.

With the bar selected I hit Ctrl-F8 (regenerate selected bar).
And I got this message:

"There is no RealTracks on this Track.
Would you like to select one?"
This happens because the track you had selected in the mixer was empty - partial regeneration works on a track-by-track basis not for all tracks. By default BB selects the Melody track when you first open the program, but BB doesn't use the Melody track for styles, so likely it was correct that there was no RealTrack on that track.

Take a look at chapter 7 of the 2024 instruction manual here, and look for the header "(Re)Generate RealTracks for Regions – Auto Generation": https://www.pgmusic.com/manuals/bbw2024full/chapter7.htm#realtracks

I have deliberately frozen the Bass and Drums because after a lot of work was done I am satisfied with them

The Vibes is the track where I need the micro chords to play. It is not frozen, allowing it to be regenerated.
If you're using Ctrl-F8 to regenerate the Vibes track, please be sure to select the Vibes track before regenerating.
