Default Using Firewire and PCI audio simultaneously?

A recent case of GAS caused me to get an M-Audio Firewire 1814. This
was meant to replace an existing Delta-66. I hooked up the 1814 before
removing the Delta, so I was pleased to find that SONAR recognizes all
ports.

Then I thought, why not use the 4 in/4 out of the Delta to give me 2
analog stereo aux buses to go to my LXP-1 (OK I'm old-school) and Boss
VF-1.

This would also give me an extra S/PDIF input that I could leave hooked
up (I have 3 or 4 S/PDIF sources).

As long as I made the timing master the interface I was recording from,
does anyone see any problems with this setup? I.e. I would typically
not record the aux returns until the mix was done, so I don't
anticipate having to record on both interfaces at the same time.

On the other hand, assuming I did want to record on both, is it
adequate to sync them via S/PDIF? The Delta does not have a word clock
input.

Thanks!

Gary

As long as you slave the 2nd unit to the first using S/PDIF you should be
fine sync-wise.

Me? LOL that was months ago. I hardly ever stop in here any more...
Yes I did. Got AudioPhile Fireware 1814 and Delta 66 going
simultaneously. Using the Delta for 2 stereo aux send/return to some
old fx units.

Using is too strong a word, between my job sending me to the east coast
every month and my twins entering their twos uhm I am lacking in both
spare time and motivation/inspiration. But it worked fine when I tried
it and I'm not even convinced of the need to synchronize them, esp. for
a reverb send/return.

Thanks for replying. I didn't see this thread when you originally
posted because it wasn't an issue for me then, nor could I offer advice
because I didn't even have firewire. FWIW, I think being able to sync
the cards may help, because I can't get my Audiophile PCI card and
M-Audio Revolution to play nicely together, not when audio is going in
the AP, anyway--and you can't sync those two because the Revo doesn't
have S/PDIF.

So - what happens? I would think that the worst thing would be some
sort of free-running drift since the clocks aren't synchronized - and
really only imagine that causing a problem sonically if the same signal
were somehow going to both interfaces, causing some sort of flanging
sound possibly if they were to be mixed. But if completely different
signals are going in, who's going to notice something like this?
(maybe I'm wrong?!?)

What happens is if audio is coming out of the Revo and going in the AP
at the same time one card or the other will stutter(not flange, and it
is very noticeable), depending on which are the playback and record
timing masters. I forget how the M-Audio tech explained it; but what I
can tell you is when the AP is master the latency slider measures in
increments of 1.5 ms, and when the Revo is master it measures in
increments of 10ms, even if the samples are set the same in the control
panels of both cards. I've been over it thoroughly with M-Audio.

Your investigation is way more in depth than my experiment was, so
don't read too much into my results!

Oh, that was in response to the other poster. I have pretty much
decided to either replace or add another Delta card to my setup, which
will give me an extra set of outputs when needed. The possibility of
syncing up an additional card would then be a bonus.

Sorry, that was me using a different screen name.
