I think it should be. Remember that people successfully run
multiple analog multitrack machines in sync by controlling the
motor of one with some kind of timecode printed on the other.
We're dealing with physical motors so I suspect the "vibrato" in
that case is a lot more and nobody complained about it.
Another interesting comparison is modular digital multitracks
such as ADAT and DA-88. Anybody know how sync works on those
beasties?
