I’m working on a trio piece: piano, cello and bass clarinet.
I’m writing both, score and part, in transposed pitch, but the part layout using the same clefs transpose a higher octave than the score one.
I can’t understand why and how to fix.
The second voice is a fake instrument to notate in some points unpitched sounds like “key rattle” on a single line.
I tried also to work with the “octave shift” properties but also if I check “set local proprieties: locally” it seems to affect both layouts.
That’s also why you noticed this strange behaviours only at the beginning.
And for the 9th/2nd issue: bass clarinet has several ways to transpose that’s why there are three Bb bass clarinet in the instrument list (I need ↓2nd for bass clef and ↓9th for treble clef) but at the moment that’s not the issue I’m struggling with.
