Hi,

As i know, most of the USB audio interface in 2 channel input. But nowadays, there are a lot of USB audio interface or even a USB Mixer comes with more than 2 channel inputs. In this case, do it means c'ld recording in Multitrack like what Firewire Audio Interface did? or, it still a Master Stereo Channel on USB recording? Thanks for explaination with appreciation.

below are some samples of USB devices...
