SMPTE Sychroniser XR300 synced via audio tracks to create midi time code input

I have audio tracks from an old 16 track recording imported into Cubase Pro 12.
There is a SMPTE time code track on this multitrack recording which I have inputed into a XR300 SMPTE Synchroniser. I have a midi sync output from this device going into the midi in on my Tascam audio interface back into Cubase Pro 12. How can I create a midi time code back on my project this way?
