Understandably, that seems to be the consensus of most DAW developers. Most serious composers use dedicated scoring software anyway, so having it in a DAW would be of little interest to them.TSC wrote:Creating a scoring app is a massive undertaking - easy to do badly, very difficult to do well!
I will say though, that it would be neat to have a simple notation 'viewer', so that you could see your MIDI data on a traditional staff in a separate window from the piano roll editor. Maybe not for input, or editing, but just to have an overall view of the MIDI tracks being performed during playback. That might give you a better contextual view of the arrangement as you are working.
But of course, exporting the MIDI to a real scoring application would be the objective for serious workflow.
