Ok, so still running my 700c and 700R with X3. Just bought the Octa capture to give me the extra 8 pre's, but can't get them to see each other...
works fine here with X3 and Platinum on win7
just make sure you have the latest firmware and latest drivers for both units
check that each interface is properly installed and working fine by itself
then follow the setup instructions from the manuals - most important will be to switch OC to VS EXPAND mode and setup master/slave sync properly with COAX cable plugged into proper ports (an easy one to get wrong)
VS 700 needs to be set to sync to "Digital 1" before use (you can do this via desktop shortcut loading your default file into the vS-700 IO editor)
first test at larger ASIO buffers to ensure you don't get any dropouts (if so check setup tips above)
then hike down ASIO buffers (mine run really low - setting 3 @ 96 kHz)
hope that helps :-)
