[LAU] Audio Interface for live Processing

[Saul Rayson]

Hi James,

I expected the focusrite Saffire 6 to work but it is not recognised by the
system or Jack. Then I read this

http://ubuntuforums.org/showthread.php?t=1486482&page=3  from last year.
Maybe I'm doing something wrong but it would appear that there is no easy
solution.

Would usb 1 be fast enough for live processing?

What latency do you get with 2i4 (USB2) looks good.

Ralf, thanks for your calculations.

Cheers,

Saul
