Cubase Pro 9 Chord Pad Keyboard Display Issue

There are some graphical glitches in the chord pad keyboard display (music keyboard displaying chording and remote keys)

  1. I activate my Piano plugin (ezkeys) which is loaded as a Track Plugin in my otherwise empty project template.
  2. I switch to Chord Pads in the lower zone.
  3. I select a chord preset for the chord pads
  4. I enable remote control
  5. I trigger the remote control, sounding chords correctly
  6. I notice that the graphical musical keyboard has missing trigger keys, and also black blocks (where they shouldn’t be) on the white keys.
  7. I have confirmed that this is not particular to any plugin… and is a graphical error, as it appears on my screen.
