Dear Nicolas, Wow! I personally do not (or have not yet) used midi playback on LilyPond/Frescobaldi, but goodness isn’t this exciting! I believe this can be inviting to those who have used such playback features on other software programs.
I can’t really comment any further (aside from that I am inclined to think this should follow point-and-click options where the features could be turned off if needed), but I wanted to express my excitement in this; I hope more development will follow! Regards, Yoshi
