Microtonality help with transposition

Yes. You have to do things in this order: Select the beat where you want the key sig, then select the tonality system, and then input the open (atonal) key sig If you don’t do them in that order, any key sig you input will be in the existing tonality system at that point (probably 12-EDO).
