Wrong key when changing instrument
I used Tchaikovsky, Chanson Triste for Piano and Cello (by shutterfreak) in Bb
1. Change "Schlüssel" to Violinschlüssel -> Notation/Tonart/Key Change is ok
2. Change Instrument from Cello to Tenor Sax, key stays in Bb -> should go to C
3. Press "Kingende Notation" - key goes to Ab, should go to Bb
Same effect with other transposing instrument like Baritone Sax.
