Fingerings anomaly

[Lillie_Harris]

It’s intended based on the physicalities implied by fingerings and brass instrument slide/valve positions, e.g. as described by Leo in this earlier thread

Fingerings 8 and 9 not working

Fingerings 0-5 cover actual fingers (typically 1-5 for keyboard instruments and 0-4 for string instruments). “Fingerings” 1-7 cover the number of slide positions on a trombone. Combined 1, 2 and 3 (e.g. “12” and “13”) cover valve combinations on valved brass instruments. 8 and 9 are none of these things, so they’re not possible via the Fingering functionality.

Perhaps you could use lyrics instead of fingerings to number pitches in your serialist music?
