Actually they're not cheap at all. The main benefit of usb audio devices 
is the portability. However, now that firewire is becoming a much 
cheaper alternative usb devices are probably going to become obsolete 
like the Laser disc has.

But it would be very nice if I could use my usb quattro to manipulate 
the sounds of my bandmates in realtime at lowlatency. I tried with ssm 
at 64 bytes and there was noticible lag so we couldn't do anything live.

The best I can get out of jack is 1024 but 2048 is more reliable.

Having to use PCI devices is a PITA when you are trying to gig at 
different venues as they require a lot more space. There is also 
something elegant about being able to instantly connect your setup to a 
different computer by simply moving the USB cable.

However, it could be said that any sound device running on a PC is a 
waste of time for serious musos as you cannot beat the sound quality 
from a top of the line recording studio.

Each to their own but I would just like to be able to show people the 
true potential of Linux Audio and currently I cannot unless I get a PCI 
device. That, IMO, is what really sucks.

========================================

Being on stage with the band in front of crowds shouting, "Get off! No! 
We want normal music!", I think that was more like acting than anything 
I've ever done.
