There is a minor bug which makes MIDI control rather uncomfortable.
Each preset change by MIDI Program Change provides a warning
That warning appeares though there is nothing changed at actual preset. It is possible to prevent from that message, when "Ask To Save Modified Prestes" optin is unchecked, but that might be dangerous.

I sent this message to CA support too. Danny wrote, that until now all CA instruments provide this issue. (I did not recognise that yet) It will be fixed with next updates.
