I'm Peter Nij Bijvank from Holland and I'm also an owner of 3 c-port cards, I try to use them in my studio but I think there is still something wrong with this product (or the driver).
I've got a P4 with a soyo dragon ultra mobo with raid and two 80 G hd's. (I also tried a similar board from ASUS p4b533e)
For software I use Steinberg Nuendo or Cooledit pro 2.1
I posted a message on the forum some months ago and Skinnah (Matt) reacted on this and together we now try to find out where the problem is.
Could anyone please try this for me on their system: apply the same 1 Khz signal (with Y-splitter or something) to input 1 (first input of first rack) and input 9 (first input of second rack), now mix them together after recording. You'll notice the signals do not exactly add up, there is a delay between the first and the second rack (and even more with a third rack of course).
Another thing to try; take a cd player and connect channel L to input 1 and channel R to input 9, now record this and with playback try to make a mono signal out of this. You'll notice Phase-errors.
The three cards all have different timings with every new project you create or will be different with every sample rate you try (especially with higher sample-rates)
With ASIO it can run up to 17 milli seconds(!!)
Suppose you have a drum kit setup in the studio and the symbal microfoons are connected to the second rack.
My conclusion is that I can't do a proper live recording session with this delay.
This is my studio :www.fraizle.com/template.php...id=30&offset=10 and I did my first CD-production on a loaned RME Hammerfall system built into the pc I mentioned earlier.
I'm very curious about yours and other multiple card users experiences.
