I created a short track, then duplicated it several times, them put them side-by-side. Selecting them all, I the grouped them. However, when I double click on the track to open the midi editor, it only opens the piece that I clicked on. How do you merge the pieces together in one track to make it a single object so that you can control its properties all at once rather than that of the individual pieces? I'm Using 2023 Premium in Win 11..
