The question is: How DO you go about syncing those machines? Well, you won't get a straight answer out of me either.
You need one of the machines to have some kind of ability to be a synchonized slave to an external source. Most cheaper multitracks don't have that, but it seems like the TSR-8 does! Also, 4-track reel-to-reels aren't very common anymore, so I guess it's pretty old? Then it might be able to sync, you never know, high-end multitracks often can.
You will need some kind of external equipment to sync the TSR-8
, but exactly what, I don't know. You could try talking to Tascam, or some good music dealer, if you know any.
Otherwise, you could up your total number of tracks from 8 to 12 by doing a first stereo-mix from 6 of the 8-track tracks though.
Other ways of doing it is mixing 8 tracks to the 4-track and then recording two tracks on the 4-track and mixing that back onto the 8-track (that way you can also keep the original 8 tracks around if you need a remix). But that will add one more generation of noise.
But the best would be if you could sync the to reel-to-reels. No, you can't mix 8 tracks down to two, and then 8 more to the other two, since you need one track on each for sync, but you'll get the 8-track stereo-mix, + 7 more tracks + the one left over on the 4-track, all in all 16 tracks.
Or you could just sync them to get 10 tracks instead of 8 when thats enough. Then you don't have to do any mixdowns at all!
Personally I have yet to find a situation where I need more than 8 tracks.
Good luck in finding sync-equipment!
