I think I can say this.
I just tested RB build 4 release 4 and all works as it should. Hopefully nothing new pops its head up.
I downloaded the new build and I reopened the RB file I had been working with above after the update. All was good except for one 8 bar section I had changed the chords in and regenerated before the upload. The RealTracks in that section were not playing the correct chords when I first opened the file with the new build. I regenerated the section and the regeneration corrected the audio. I saved a copy before regenerating in case there is something that pops up I can send that file to PG Music staff.
"Thank you Charlie for doing this. You added validity to my being. "
Lol, you said in 5 steps what I was trying to say in 100 posts in the other thread.
