I've done a lot of editing following the process Alec described. If you change voices, for example the bass sound, on all of the intro's, fills, variations, and endings, wonder how many buttons would have to be pressed? It sure is laborious. I'd give up half of what's on my 6500 if I could get one large page or screen of Composer where everything to change could be viewed at once, make the desired changes, then push the button one time. To me, that would be a great step forward.
