Testing Diminished Chords and their Notation
This is the file I was struggling with.
I examined the notation of a diminished chord, because one single chord can appear with 4 (and in this example even 5) different names. That means a lot for the notation in the different Key Signatures.
Edim7 should contain E-G-Bb-Db Gdim7 should contain G-Bb-Db-Fb F##dim7 should contain F##-A#-C#-E (enharmonic equal to Gdim7, but occurs in the Key of G#minor) A#dim7 should contain A#-C#-E-G C#dim7 should contain C#-E-G-Bb
and in Sibelius with correct chordname and correct notation of the notes

B.t.w. I think that it would be very convenient to have the previous chordnames of the file in a Cache Memory, and to be able to change Chordnames without deleting at first and completely re-input the changed Chordname (like the CTRL-Click on the Chord Name Text button in PTE 1.7).
