In Studio One, it is possible to drag an event to the chord track, and, if chords are recognized, chords are added to the chord track.
The reverse should be possible:
When the chord track contains chords, it should be possible to drag it to a midi track in order for presonus to generate the notes in the midi track.
This would be the fastest way to enter chords in S1 for many people: just write their names in the chord track or create them with the Chord selector, then drag & drop chord track into midi event.
