I am running Cubase SX3 and a 2408 mk2. SX3 does not sync to word clock (SX2 does). Right now I am using the SPDIF connection from my Rosetta to my 2408. If I use the ADAT connection instead, do I theoretically not need the word clock sync? As well in order to have proper ADAT sync with my RME card (on my Giga machine) I need to use the "handshake" method with the 2408 otherwise I get clicking.
