Sorry. Let's just say there are many possible combinations!

What an interesting way to think of it: time-space drift. To get the
74 min takes in sync by changing the sample rate, 1 second per 4400
is too small to create a noticeable pitch shift. MD's are on par
with traditional 16mm film "sync" which was +/- 4 frames (1/6 second)
in 11 mins wasn't it?

I'm hoping to get back to something more like a hiking system with
the 744 and maybe the letrosonics-- if they ever make the 744. Dozing
off with headphones in a tent or van with mics spread all around is a
lot of fun too. Rob D
