The problem follows the song (.sgu) file.
It is the same on the 64 and 32 bit version 2019.

What setting controls what is shown in the radio button ribbon at the top of the screen?

For the problem song and MIDI (DIXIELAND 3) style it changes to:
Master Silence Silence Drums Silence Silence Melody Soloist Thru Audio.
Only drums play.

For other songs and MIDI (DIXIELAND 3)style, it is:
Master Bass Trombone Drums Banjo Reed Melody...

It is the same style used so why is it different?
