Transpose track design bug

When using a global transpose track, midi notes (with ‘indicate transpositions’ enabled) are no longer movable using the mouse.

For example:

    1. Create empty project
    • Add an midi track
      1. Add a transpose track and set to anything other than 0
      2. enable “indicate transposition” on key editor
      3. click on note, go to drag, note fails to move.

Mac OS 26, Cubase version 15.0.30

Hi,
I followed your instructions but I can’t replicate the issue here on Windows 11 Cubase 15.0.30. Everything works as expected - I can still move all MIDI notes with the mouse.

Have you tried to start the project with preferences temporarily disabled? On Mac: hold Cmd + Option + Shift after launching Cubase and pick this option in the dialog window that pops up.
Maybe your preferences got corrupted?
