Ardour and Lexicon Omega USB Interface: It works!
I don't know how or why it works, but it does! I had connected my Lexicon Omega to my dell laptop with Ubuntu 7.04 installed to use a midi pipe organ program, and I recently decided to download and install Ardour. I just got it opened up and found that it appears that the recording inputs from the Lexicon Omega work as well as the MIDI inputs. I did not think this was possible before, so I'm pretty happy. Now I can record 4 track with my laptop and 8 track with my desktop! So anyway, just wanted to put this out there in case someone was curious. I can't guarantee success like mine, but try it out, it might work.
