Chord symbol mistery


When i use cubase to make chord symbols in MIDI files most of them work but some of them give problems in players like PCLP6 or MidiFileOptimizer. Expeccially sus4 chords dissapear when chords in score editor are exported as Midi file and played.

Can anybody tell me if it it’s possible to export chord symbols as XF standard? Or does anyone know an other way to edit chord symbols in Cubase?
