Playback: tied trills
I saw something mentioned 5+ years ago which may be similar. Since it may still be the same thing I thought I would bring it up, again.
Tied notes over multiple measures that are trills or a roll for percussion, if you use the trill sign(s), sound for the first measure, then at least the second measure has no sound. Some occurrences do not sound the third measure and some do. Very irregular.
It was suggested to just leave the ties off and that works ok in MS, but not at all with real performers. And in a large score with multiple times happening it would be very difficult to clear and reaccert the ties over 100+ pages. I hope mentioning this again might bring it back into focus.
