Is there any way to recreate a double trill with 2 auxiliary notes (with different noteheads) as shown here?:
The closest I’ve managed to get with Dorico is this unsightly mess:
And this is with considerable ‘hacking’ already: 2 voices with changes to the voice column index, dragging stems, creating 2 custom notehead sets… (far harder than it is to hack the same result in Sib, with which the first example is created).
I know it probably sounds a bit mental, but this is a game-changer for me; I use this technique all the time in my music; it’s commonly used by Saariaho and some others.
