I have a score containing a Bb Clarinet staff...it's in "D Concert" so clarinet is in his "E".
I was asked to re-write it for "A" Clarinet.
I select all the bars, and 'change instrument' to "Clarinet in A".
Everything works fine EXCEPT, the first 16 measures (only) are not transposed properly.
Notes and key signature remain as if it were still a Bb Clarinet part.
My "work-around" .. I defined this staff, using 'staff attributes', to have an independent key signature.
Then I changed the key of the first 16 measures to "Eb concert" and it put the "A Clarinet" into his "F" which
is the desired end result.
BUT ... ??? why ???
