Would you please seriously consider implementing multiple midi clip/track editing (in one view) ? This includes note and automation editing. An overlapping feature request is editing multiple automation curves of one clip in one view (e.g. modulation and expression).
This is possible in most DAW's, including Cubase, Pro Tools, Sonar, Digital Performer - and even BitWig. I love Live and have used it for many years now, but lacking this rather basic functionality is an unfortunate dealbreaker for my current work of writing film music. BitWig would be closest to what I'm looking for, but I would hate to lose all the cool things in Live.
Currently I need to jump back and forth between multiple instrument tracks, over and over again, trying to remember their contents note by note in your head, when e.g. writing harmonic passages for multiple instruments. Think about writing chords for an orchestra, each section playing one note. Getting the orchestra to play just one good-sounding chord takes a long time. Building any kind of harmonic (orchestral) film music just takes too long to make it worthwile with Live.
Good discussion on the subject (started four years ago
