I think we have to prove the 8pre protocol is not the same than the Traveler/828mkII one before trying to sniff the 8pre protocol. Sniffing is not the fastest and easiest thing; if we could reuse the work made by Jonathan it should be not so bad. > > As a followup to my last email, I looked over the MOTU 8pre docs and > they > > state very emphatically that the install CD needs to be run before the > > 8pre is connected to the machine's firewire port and powered up, so it > > would seem that the 8pre is expecting to see a certain response or > > sequence of responses from the host machine before it goes into > interface > > mode. > > Yes and no.

The "converter" mode of the 8pre should be the "stand alone" mode of the Traveler/828mkII (with predefined CueMix parameters).
