Mics into USB audio interface into 8 track tape machine??

So I bought a beat up Tascam portastudio 488 tape recorder, and when I try and bounce multiple tracks (i.e drums) to a single a track it never works. It's quite a temperamental machine.



But I was thinking about whether I could put multiple inputs (i.e drums) into my Tascam US-1641 audio interface, and then record those multiple channels onto a single track on the tape machine. Any ideas?



Thanks,

Joel
