Summing FF+Adat Phasing- Any Workaround?

Hi everyone,

I don't write very often cause the most issues are already well treated here, but
today I got aware of a problem, i couldn't find out more about.

I'm summing 16 channels out of the box using cubase sx3 and a FF with an ADI8 pro via ADAT.
today I found out, that the output latency through the ADAT is 3 samples higher than through the FF.
so i get a pretty bad and phasy signal if I run e.g. a snare drum out of the FF an send it in cubase to a bus with a comp that goes out to the ADAT interface.
That leads to the problem that I would have to seperate the whole signal chain and that every signal including all it's sends should run over the one or the other.
The signals through the adat would have to be moved by 3 samples.
This could be a problem using a room to melt signals together or compression and so on, because you can't delay the groups and the effect channels.
Why does cubase compensate the latency of the incomming signals comming through FF and ADAT, but have no possibility to compensate the outs?
is there a plugin for the busses, like in pro tools?

thanks and greetz,

michael

Its a problem for all platforms...Cubase,ProTools, etc. The latency is not in the buss but mixing the converted analog track with the original digital one. Your best bet is once you go analog stay there until the end or use plug ins for the comps.

sorry, my english is not that good ( and sometimes also my brain heh ) and maybe i didn't make my self clear but, in the summing stage every signal is already one time converted and is send one more time out of the box for summing. so the signals have the same amount of conversions, but sending the same track trough the FF and the ADI8 pro will delay the ADAT signal about 3 samples and start to phase, so i move it by that amount.
But if i send it through a digital bus in cubase wich doesn't use the same converter it will phase and i can't do anything, so i would need a way to manually delay everything.
Or am I wrong?

Thanks for the quick reply and all the bes

Michael

Is there no sample delay plugin in Cubase?
If you're on PC, you could use this: http://www.voxengo.com/product/sampledelay/

You simply would have to put it on a setting of 3samples on the tracks/busses that directly output to the ADAT convertor.

Thanks DrDeltaM,
I think that's what I was looking for.
I'm on PC,
I'll try that out.
Like the rest of the Voxengo stuff, cool company.

All the best,

Michael

Hope it works out for you!

I made a mistake by saying you've to put it on the tracks/busses that output to the ADAT convertor tho. The plugin of course needs to be placed on the tracks/busses that output to the FF convertors, as those outputs are 3 samples 'faster', so need the extra delay.

your right. thanks

pling!!!

now i have it....
i only have to put the +3 samples delay into an insert in every cubase output channel that goes to the FF, and i won't have to worry about anything else.
Pling!!!

sorry but my brain was out of order.....
