Ok thanks, but why is the same loop you record in the DAW allways a bit different ? it wont to Null in the DAW,  i can  to null with all my other hardware over SPDIF .

You still dont seem to have reported an actual 'problem' that I can see. If your goal is to acheive a track of silence, just dont plug anything in . ... or perhaps use one of your other interfaces, as you seem to be able to acheive your inverted track home made silence using those.

Seriously though, I really dont understand. Are you really saying that you can route the HD loop out through analog to another interface, then SPDIF to your DAW and produce a track that will invert and sum to null. I'd be somewhat suprised given the need for the analog stage. Alternatively, if you are using a differrent source, then thats not apples and apples.

Furthermore, despite the possible theory that the sound emmited by the looper will be identical each time, I would personally suggest that this would be very very unlikely. Perhaps if you were using no effects and no sims it 'may' be possible? I mean what type of variation are you experiencing.

If you have any genuine concern here (and I am having to be a little artistic here in your favour) then it could be you are saying that the POD does not maintain a consistent tone through SPDIF. If this is at all representative of your concern I would suggest that you post an example of two tonally different takes so we can actually hear and comment upon the difference.

If however you are merely curious regarding the tech involved (which I also suffer from, from time to time) then I would make this clearer and voice your questions accordingly. The reality is, however, if this is your angle, then few here would be able to give you what you seek.

I am a little relieved, however, that you have dropped your SCSM enquiries.
