So, basically what I’m after is a way to speed up addition of tremolos.
Proposal (only applies if multiple notes are selected)
If the first note si a quarter note or longer, it and all other quarter+ notes in the selection get the full tremolo. Shorter durations are scaled as appropriate…
So, for instance, 2 stroke tremolo selected, quarters get 2 strokes, 8th notes get one stroke, 16th and shorter no trem.
