Thanks for the info. This is *exactly* what I needed to know. With
this info, I'll be ready to rock on Monday. As far as JAMin goes, I've
never used it. For now, I don't think I want to learn about it - just
because I'm going slightly crazy trying to figure out ardour and this
Delta card I got 2 days ago. Isn't it great how I leave so much time to
learn how to do something before I actually do it? :) Computer nerds
are weird... ;-)
For now, I'll just work on getting the best recording from ardour that I
possibly can. When that isn't good enough, I'll start looking for other

Luckily, I found the envy24control about 30 minutes before I installed
my delta. I would have gone insane without it. But, because I'm so
inexperienced with it, there are *loads* of stuff I don't know much
about. For instance... I don't have a clue (or a very big clue) about
the loads of faders in the "analog volume" portion of the program.
There is DAC, (Digital to Audio Converter, maybe?) ADC (Analog ->
Digitcal Converter?), and another one... I figured out that the DAC is
the one I needed to turn up so I could hear the headphones, but that's
about it. The others, I haven't had time to fiddle with..... Anyway...
So, to do the hardware monitoring, I just set all of the analog inputs
in the Router page to the Monitor Mix, and that will turn on the
Hardware Monitoring? (I've got the headphones set to analog outs 1 and
2). That makes sense.
One other problem we had was.... monitoring / changing the levels of
the mic inputs (ins 1 and 2), or any inputs for that matter. I couldn't
find any controls anywhere that intuitively told me "These are the
faders you need to adjust in order to control the level of input". I
just assumed the card didn't have that capability. I read the manual
(which, unfortunately, was written for windows), so I knew about the
jumpers on the card (mic / line level).. Is that the only way to adjust
the input levels? I'm kinda sensing that it's not, and I'm just missing
something somewhere. I hope this is the case.

Consider it done. Thanks for the suggestion.

Isn't group therapy fun? I hope someone has a problem in the future
that I can help out with, so I can give, as well as take, from this
