Maybe it could be a viable approach if all the (continous) automation would be prepared in a “real” DAW like Ableton/Cubase/Logic Pro and saved as a midi file… this midi file (using the middi file player) could then be played in sync to the actual acoustical backing track (using the SAFP).
That way you would have the same midi track for automation available in any DAW you’re about to use - in studio or live.
