Composers are crying out for accurate playback directly from the score so NO additional editing in the note editor and automation lane is required. A key problem at the moment is that dynamic markings do not change dynamics(!) for the majority of orchestral libraries. Please let us assign p, pp, f etc and hairpins to a MIDI CC of our choice so this will actually work.
But overall as the title says please put more emphasis on playback. All the technology is HERE NOW for a "score to professional sounding mockup" experience. Staffpad has nailed it. You could too and it would be amazing. I guarantee you would see a mass migration of film composers to Studio One. This is THE feature we want.
