Tremolo notation is not working
As I was transcribing Les Etoiles, a mezzo soprano art song with piano and cello accompaniment by an 19th century composer Pauline Viardot, the tremolo function stopped working. This piece includes over a hundred clusters of tremolo in the piano accompaniment. The tremolo command works in only one location per staff per measure in random order. I have used the tremolo function before in other transcription work in the past and encountered no issues. I am not certain if this malfunction is due to the extreme number of tremolos per measure (up to 4 in each staff with a tremolo cluster for every dotted quarter beat in a 12-8 time signature). My software is up to date, and I have restarted the computer several times. It made no difference.
This is the score I wrote. The tremolo part lasts from page 3 to 5.
I couldn't understand what the problem was.
Attached is a GIF of what I did.
Note: I didn't pay attention to some durations in the bottom line. I just checked if the command is working.
Since I don't use the tremolo heavily (in just a few places), I don't know how it worked differently before.
I don't see any tremolo in the entire score, nothing like descibed in https://musescore.org/en/handbook/3/tremolo
The above GIF shows how to use those, how to change your score to use them.
Indeed, adding a tremolo to this score seems to work fine for me (I choose the first pair of dotted eighths in the piano part on page 3.
If you are seeing a case where is does not work, please give precise steps to reproduce the problem.
