MIDI device panel controls not updating

I’m on Cubase 6.5.

When using a MIDI device panel, the on screen control does not move when moving the physical knobs on the synth itself. I can see the MIDI traffic but no on screen updates. This works for the same panel in Cubase 9 (except for 14 bit MSB/LSB CCs…).

Is there some way of enabling the on screen update for 6.5?

And is there any knowledge about the missing updates for the 14 bit MSB/LSB CCs?
