Hi,

what would, in your opinion, be a recommended USB Audio Interface for
multitrack studio recording?

In the past, I was happy with M-Audio Delta 10/10. It was using a
PCI-Extention Card. Now, I'm searching for a replacement using USB.

It could have fewer IO-Ports and I need no Effects-Processing on the
card. Important is, if possible, out of the box connecting via jackd and
channel adjusting via alsa mixer.
