Chord track can not show chord in the track ,Chords can shows in the chord editor, but in the chord track ,it just a X chord symbol .
The problem shows in Cubase 10.5.2 ,and it is ok when i downgrade to 10.0.6.
Ok…i know the reason,
there is a function called in control with my novation launckey , and i did the wrong settings in cubase
'midi port settings ’ I ticketed the ‘ALL MIDI’ option ,so there is a constantly c-2 note in piano roll .so this affects the chord track.
