Hello,
searching for this bug on sf using terms “accidentals + merged”,
I found only #546 said to have been solved for ages.
Still, the output doesn’t match at least /my/ expectations:
notes should either not be merged at all, or there should be
stacked accidentals indicating which one applies to which Voice.
find attached a minimal example
If I add a ! to the note on the third beat in the upper voice,
I get at least both a natural and a sharp sign, leaving it to
the reader which belongs to which Voice, but it still doesn’t
help with the case on the second beat.
regards,
