Hallo David,
thankyou very much. It was a very quickly answer!

I really mean the Chord Symbols above the score. Cause in another midi-program (Optimizer7 / midiland) the chordsymbols stay, although I transpose the midifile and exported it.

But now I know, that I did not make a mistake by working with the composer.
Thanks again!
Bernd Dellwig
