Yes, 2021 BIAB & RealBand.

Regarding which "PAK" do I have... if I open BIAB and click Help > What add ons do I have there are too many to list here so I'm unsure how to answer that question

Yes, while looking at the RealBand styles I can click "Load Demo Song"

When I do I see 4 populated tracks...
BB Melody - Acoustic Grand Piano
BB Soloist - Acoustic Bass
BB Real Base 400
BB RealDrums-Jazz-TerryClarke

While your view shows 5 populated tracks.

Question 1: Will RealBaand Styles list Styles even if I don't have the right PAK's?
Question 2: To share an image on the forum do I have to have it online in a public folder... like on a public Google Drive folder... or what?

Also, of note, if I just double click the style I hear one arrangement playing but if I click "Load Demo Song" it sounds different... and actually not so good...
So maybe the system can't find all the "parts" so some instruments are missing...
What do you think?

Thanks for the help.
