Auto Placement of Tremolos is Incorrect
Pictured are 3 screenshots of the instrument MDL Rail. When attempting to place any sort of roll marking (tremolo) on a note (regardless of duration), the Automatic placement feature places it incorrectly: so much so, that for a single tremolo line, it is completely below the note.
Perhaps a rule could be developed for Automatic placement of Tremolos? Quite tedious to go through each one and turn it off and then manually adjust each Tremolo's position.
I attempted to use Tremolo's when writing for Solo Violin as well (pictured), just to check that it wasn't a plug-in (MuseScore Drumline) only issue. It appears to be a general Editor issue.
