Depending on the type of interface you use the 48 can probably only be used as master in a sync situation. you'll have to record SMPTE time code via an audio connection to one track, 1 or 8 is best, avoiding audio/magnetic spillover to an adjacent track, and such an interface that can read it back and convert it to MIDI timecode (MTC). Also a computer and the version of say windows you use might define what interface you can use. i still have an old Unitor 8 serial version for sale, but it has been discontinued and only works with older MAC and Windows sytems. How ever as stand-alone unit it can read SMPTE and send out MTC. More professional systems like a Adams Zeta III can control a recorder with the proper interfaces connected from software like Cubase, but it will need the MIDI option fitted. -F
