David,
Thanks, this confirms my gut feeling.
Yeah, I have always said in my software career that "when a developer does more harm to the software than improving it, the software is ready to be launched".
So it is here. I have found the issue related to (a) which came in with a fix of copying beams with build 3.0.6-132. It fixes beam copying but the fix doubles/multiplies other elements like sound changes and lyrics. Thanks for your help.
