MIDI Transpose Issue

Not seeing that problem here. But maybe I don’t understand. (e.g., there is no tool called the “midi transpose tool”)

Try this in a new, empty project to investigate:

  1. Create one midi track
  2. Create one midi part
  3. Open the part in the Key Editor, add a bunch of notes
  4. Close Key Editor
  5. With the Select tool, click on the midi part to select it.
  6. Open Transpose Setup… from the MIDI menu
  7. Set Semitones to -12, and make sure nothing else is activated in that dialog.
  8. Hit OK

What happens?
