Hi ROG,
Thanks that clue sorted it out.
Actually, if you have audio or Midi in the song it will transpose OK.
My mistake was when prior to transposing I usually remove the tracks to save converting all the audio tracks, then I regenerate the tracks.
All's well now I see what's happening, appreciate the help.
