synchronization ardour 4-hydrogen

Hì everybody, I’ve got a little problem with the new Ardour 4.0.
I can’t start ardour and hydrogen at the same time becouse even if jack is started i can only choose the server audio between “internal” and “MTC”.
So if i click on the start button of ardour, hydrogen doesn’t start, bui I need hydrogen and ardour starting at the same time!
Thank you a lot!

You need to go to Preferences and change the external sync source from MTC to JACK.

Thank you! I spent my monday night looking at the preferencies of ardour but i miss this tips!
