Hi again, BIABman.

The SGU file using piano RT735 sounded like it had artifacts present. I did a few things. These were...

1) In Song Settings...
(a) Make sure that "Force song to simple arrangement" is off
(b) Turn on "Avoid transpositions in Realtracks".
(c) Set Natural Arrangements to "Enable for this song".

2) Press CTRL+F7 and make sure the "Simpler" is unchecked for the Piano Realtrack.

3) Turn off the "Auto-fix Sour Notes" (this is accessed by right-clicking on the track, and selecting "Track Settings" from the menu that pops up).

4) Unfreeze the track and regenerate the song.

After I did the above, I got the below sound.

When it came to the artifacts I was hearing, I think the "Auto-fix sour notes" was the main culprit. (I'm not 100% sure of this, though, without further testing.)

I hope this helps,
