Two different microtonal accidentals in the same measure?


I’m pondering if it’s possible to use both Gould arrows and Stein-Zimmermann accidentals in the same measure (on different instruments)? If one writes for example quarter tones with Stein-Zimmermann accidentals and 6th tones with Gould arrows?

You just need to create a custom tonality system that includes all the needed symbol definitions.
