I transfered my VS-1680 track a couple of years ago to Logic. It was actually quite easy. Logic and the VS sync very nice and I made 10 to 12 passes per song (took a few days) and got all of it into Logic. I sent everything thru the digital outs to my Motu's digital in, to Logic, to keep it all in the digital world
This subject was discussed a couple weeks ago

The only difference is I was talking about the VS as the master and Logic as the slave. but it can work either way. you just need to get into the midi section of the VS and set it to sync to MTC as a slave and set Logic to transmit MTC. Make sure the MTC format is the same on both machines
Logic Synchronization is discussed in the manual on page 605, I suggest you read it, it will help you.
Also you will ned to check the VS manual to see where to set it to send and receive MTC, It's been a while but I believe it is in the midi section, but I think there were things to set under a couple of different menu's. if you don't have a manual, then just look through the menu's to see what applies. Maybe you can google a manual on line also.
hope this helps
