Kai, thanks for the reply.
I have a few more questions.

This confuses me. In qjackctl's connections screen, I see 18 capture
channels on the RME. My impression is that these are mono, not stereo.
I need to capture 4 of those channels, two for drums, two for guitar.
When I start ecasound like this:
> ecasound -c -r -b:128 -a:1,2 -i jack -o drums.wav -a:3,4 -i jack -o guitar.wav
Then ecasound has 4 inputs that I can connect the 4 capture channels to.
Maybe it is the "-i jack" listed twice that makes 4 input channels on
ecasound? Previously I had tried something like:
> ecasound -c -r -a:1,2,3,4 -i jack -a:1,2 -o guitar.wav -a:3,4 drums.wav
and that didn't work, I got two input channels on ecasound, and well,
that wasn't what I needed, so I was kind of thrashing around a bit
trying to discover just what all the options really do. (I did read
the man page, it's how I've gotten as far as I have, but it's rather
Actually, I need stereo for drums and stereo for guitar, and
generally I'll be wanting to transfer up to 4 stereo tracks
at once, or any combo of stereo and mono totalling up to 8
captured channels (I have just 1 ADAT connection from the
AW4416, so, 8 mono channels.)

I'll give that a try later tonight. I'm confused as above you
say "-i jack" gives a stereo chain, but you also say above
"(mono track for drums and guitar)" Perhaps you meant "stereo"
rather than "mono"? Or am I misunderstanding something still?
> More info about ecasound's JACK support and the routing logic can
Yeah, I had found those. An example of recording multiple channels
from JACK would would have helped me a lot. (Well, maybe it's asking
too much to hope someone would anticipate exactly what I want to do
and provide an example. ;-)

Ok, thanks. I didn't know about that. Especially helful because
I have no audible output from my RME, it's just connected to the
AW4416 and nothing else. To hear what I've transferred, I have to
restart JACK to use my audigy2. Being able to see some feed back
during the transfer would help a lot.

Oooh, timemachine looks interesting. Thanks.
Thanks for the tips, this gives me a lot of things to try.
