There are two settings here. One for clock and one for timecode (or something?)

As clock I can choose from:

- Intern (I believe this is what you use if you want cubase to be master)
- MIDI Clock
- ASIO
- ASIO2 / MMC

As timecode I can choose from:
- Intern
- MIDI Timecode
- ASIO
- ASIO2 / MMC

I will check that thing with the framerates. See if it works...
