Hmmm, good question. Jack is telling me I have 24 bits capture and playback at 
44.1KHz. Haven't tried it at 48 yet, but I'll do some tests once this gig on 
monday is over.

I'm not using any specific driver for the Lexicon - Jack is using alsa so 
snd-usb-audio is the driver I think. The main thing I think is that it seems 
much more stable than when I was using an edirol FA101 with freebob. That's 
probably also because I'm using Pure Dyne - Ubuntu 9.10 optimized for audio with 
the realtime kernel. I won't use anything else now.

I made the mistake of buying a comp without firewire, but this seems to have 
been a good mistake now!

Best,
Ed
