Hi all,<br>
<br>
I might be really pushing my luck here, what with all the reports of<br>
audio issues on the Pi, but has anyone heard of somebody getting<br>
multi-input audio working with a multi-input USB 2.0 audio device?<br>
<br>
I have a dream of running one of these mixers (which does 8 channel<br>
audio out over USB 2.0) into Pd and being able to manipulate all of the<br>
channels from the mixer in Pd:<br>

given they need audio drivers for windows and mac I don't like your chances on linux, let alone a Pi, except perhaps the USB1.1 mode with 2-in 2-out.<br>
<br>
Apparently the esi gigaport hd+ does 8 channels OUT from the Pis, but I have not heard of any devices working with 8 IN.<br>
<br>
By the way ... finished my degree and I'm now in Sydney, if you're heading this side of he country sometime let me know.<span class="HOEnZb"><font color="#888888"><br>
