Ossia transpose

[k.k]

I need to add a Bb Major bass clef part for an A transposing instrument as an ossia above a B♭ clarinet part. How should I transpose the ossia in Dorico? Simply copying and pasting it doesn’t work—the pitch and accidentals are incorrect.

I don’t think you can have an ossia with a different transposition.

You cannot have a different transposition but an ossia staff behaves like a standard staff, you can change clef and key individually by ALT/OPTIONRETURN in the popovers respectively.

However you have to transpose the music yourself.
