I’ve noticed the playback techniques in Play menu and indeed the 3.5.10 release notes state:
Playback techniques. The Edit Playback Playing Techniques dialog has been
renamed Edit Playback Techniques, and can now be accessed via the Play menu
as well as via the Edit button in Engrave Playing Techniques.
But, Engrave->Playing techniques and Play->Edit Playback Technique do not display the same thing
What is the relationship between the two? How are playback techniques different and how can they be used?
