[Fmpro] word clock question

[Chris Alpiar]

OK thanks. That's how i have it currently, just was wondering about it

My understanding is that the burst from the word master is needed
independantly to all devices concurrently in order to keep them resonating
at the same frequency and has nothing really to do with the sync say from 1
device to another, but more like so every device is humming in harmony.

I travel with tracks I bounce to disc from DP (to wav files or aif) at my
studio to a pro tools HD studio across town for live tracking and mixing
pretty often and it seems our tracks are slightly off from each other. Like
I had some tracks last week that were at 144 bpm tempo and by the end of 1
min the bar line was slightly off. So I was thinking maybe it had to do with
my lack of word clock pacing my machines
