Hey everyone,

You may wish to try this:

Just open the Piano Roll, right-click on the background, and then click on "Select all Notes and Graphic Events". This will highlight all the notes in red, and you can copy them by hitting Edit - Copy, or CTRL-C on your keyboard.

Then open the next tune, go to the Piano Roll again, select the S button above the Piano Roll so that you're looking at the Soloist track, and hit CTRL-V or Edit - Paste to paste the notes.

Be sure to have the piano roll at the bar you wish to start the paste.

It works. It's easy. What more can you ask?
