I'm trying to write/notate a 12:5 tuplet. The problem at hand is that MuseScore makes you select one single measure or rest when inserting a tuplet, and I want this 12:5 to be over 2.5 beats (in 4/4). As far as I know there is no way to write a single note or rest so that it covers both the half note and the eight note; if I could accomplish this then I would be able to insert the tuplet I want. Basically I can't figure out how to combine the two beats with the eight note in order to be able to insert the custom tuplet I want over those 2.5 beats. I was wondering if anyone has a solution to this.
