vinyl music et vinyl timecode at the same time - rmx

hi, i got the rmx and i am planning to use it in a mixed setup where i can use "real" vinyls and timecodes at the same time.

for example play a normal record and mix in the next song with a timecode vinyl (i got two serato scratch lives).   

can this be done...?  (i really hope so 🙂
can someone please point me to the solution?  (i am quite sure this has been asked before - but i did not find a topic)

at the moment i have the rmx connected to a laptop - but if really necessary i could connect it to a desktop which has an additional asio soundcard

thanks alot
