hiya, anyone help?
i have the exact same 2 copies of the same record, both decks set at 0 pitch control, yet if i match the beats they go out of sync with each other within a minute or so.
is this likely to be a motor issue, or could it be the records?

Perhaps the problem is that you have a little bit too much time on your hands.

you could always check if the big dots on the platters stays "in place" if they dont it might be a motor or more precisely pitch/quartz lock issue. if not maybe the records are different (unlikely)
conclusion: dunno really, sorry

Sounds like the Motor but I'd check the arm weight and check the slipmats too. Try switching the records on each deck and see if the same record or deck slows down/speeds up.

why would you need them to stay in sync for longer than a minute anyway. If you were beat juggling or something, they only need to stay synched for a few seconds right?

The motors are phase locked to the quartz crystal when the light is on. If you're really anal, you could lock both crystals together. temperature changes will affect the crystal operating frequency and therefore the rotational speed.
Maybe there is a temperature gradient between the two decks.
Its probably more likely that there is a difference in slipmats, needle friction, tone arm weight, etc. Maybe put a marker on the platter and record and after a minute stop them and see which platter has moved more relative to the vinyl?
since the 1210 manual was within arms length (just) I dug it out and it doesn't spec the absolute accuracy of the quartz lock mode. I suspect they will differ slightly since it isn't specified. If you've got a mk3 or mk5 you get dipless pitch so can tweak them close to 0% and probably get them in sync longer.
remember these are record players not scientific instruments.
I wish I had that much free time. I should not be typing this. I must get on with my work! argghhh VIIINNNNIILLLLLSSSSSSS

take only one of the records
play it for the full length of the record input/rec to PC /cubase from deck A ( warm up the PC for half an hour first)
then with the same record do the exact same ting using deck B
now in cubase look at the wav's ...trim the ins and outs of each
which is longer? deck A or B? if they are the same'ish ....do the same experiment with the other record(veyenil) and then look at the wavs?
from this you will know which is screwy .
tip dont touch the pc when your recording.
