Hello Scott and thanks.

I probably didn't really mean one-click, rather meaning a simple solution.

The first part of "Open Piano Roll and draw in the volume curve." is easy. It's the second part that has so far escaped me. Lots of strange, unexplained little symbols and icons that change with cursor position. I've taken another look at the Piano Help Panel and I guess there's more there than I thought. I always want things to be easy but sometimes that not the case. I'll keep studying it and maybe the second part of that advice will become possible!!
