In the score I’m working on (attached below) the instrument changes feature seems not to be working with the player that is holding a drum kit and a “treble staff”. I want the drummer’s part to be able to switch quickly back and forth between drum kit notation and a reduction of the rest of the ensemble’s part in treble clef. This should be able to happen on the same line. But it’s forcing it to appear on two separate lines. Is there something I’m doing wrong that’s prevent this from being possible?
