It would be great to see the chord or note played in realtime as I play into an audio or midi track or at least be able to see a basic chord display on playback. That would help to identify chords needed for other functions in Cubase Pro. I have no musical theory or training so it would be an invaluable assist for me and many other users.
In the Midi editors, turn on the Status Line and you’ll see the Current Chord Display. It shows the chord under the cursor.
