I have been using the Motormix with the Pacamara without issue.
The Motormix and BCF2000 are still the only MIDI control surfaces that I am aware of that have automatic VCS integration.
The "Echo MIDI" VCS setting (Preferences:Performance) does provide full bidirectional VCS control for a wide variety of MIDI controllers, but you have to manually assign, or "MIDI Learn", the mappings for each Kyma Sound. Those assignments are saved with the sound so it is a one-time chore. Not as easy as using the Motormix but it does have the advantage that you decide which control surface element is assigned to each sound parameter.
