>> This did not work for me.
Not sure what you mean by "that did not work". There were a bunch of suggestions, for example, did this work " First, for diagnostic purposes, try disabling the Prefs-RealTracks- Speed up generation of RealTracks, and see if the problem goes away "

>>> And if I go to change any part of the song i.e. F-5 to mute or unmute sections I have to right click and tell BB to re-generate the real-tracks so the changes stick.

That's normal.

>>> Lastly there is a marked difference between certain real-tracks and others recorded by different artists. Terry Clarke Drums for instance sound much different than Craig Scott. Were the Real-Tracks all recorded at the same studio?? With the same gear?? I can hear the difference.

No, each drummer uses his own gear. For example, the Rock Drummers don't play on the Jazz guy's kits

Have Fun!
