LynB....did run into an issue with your method while playing with it tonight....might just be me though....but perhaps this will help others trying to do this.....

1. I select the last 10 measures of my main trac
2. I set up a new unused midi track on track 16 and use "Fill" to setup an Expression CC fade in the same 10 measures of that track using data automatically filled in from the main track.
3. I then select the whole new midi track and hit copy.
3. Then I paste it, using merge, onto my main track.

In doing this, it adds the whole "new Midi" track onto the main track. In other words if the "new" midi track with the Expression cc fade in the last 10 measures is 50 measures long and I select the whole track and copy. Then I paste it, using merge onto my original track of let's say 50 measures...I end up with a new main track of 100 measures. Makes sense when I took the time to think about it.

However, if I just copy the last 10 measures of the "new Midi" track and paste with the merge function on any of my other tracks it works out fine. So the only difference then would be to not copy the whole "new" Midi track and trying to merge that.

Still, I find that I need to paste the CC copied event fade onto each track of my song but this is much easier than trying to do each track using the event list or, at least for me, trying to smoothly control my mouse using the record mixer function.

Guess I'm too much of an MS EXCEL spreadsheet user....sure would be nice to be able to highlite multiple track sections at one time and use the paste/merge function over all of them.

But really do appreciate your's and Rharv's suggestions, they'll save me a lot of time in the future and it was fun learning a new twist in RB.
