WOW!
I ran something like
-n:somename -b:1 -m:mthreaded
-a:1 -f:16,2,44100 -i tr1.raw
-a:2 -f:16,1,44100 -i tr2.wav
-a:3 -f:16,1,44100 -i tr3.wav
-a:4 -f:16,1,44100 -i tr4.wav
-a:5 -f:16,1,44100 -i tr5.wav
-a:6,7,8 -f:16,2,44100 -i loop,1
-a:2,3,4,5 -o loop,1
-a:1,6,7,8 -o /tmp/out-peppy.raw
-a:2 -erc:1,2 -ea:1200 -enm:n,n,n,n,n
-a:3 -erc,1,2 -ea:1300 -enm:n,n,n,n,n
-a:4 -erc:1,2 -ea:800 -enm:n,n,n,n,n
-a:5 -erc:1,2 -ea:1400 -enm:n,n,n,n,n
-a:6 -erc:2,1 -epp:0 -el:freeverb1,0.85,0.21,0,0 -ea:300
-a:7 -erc:1,2 -epp:100 -el:freeverb1,0.85,0.21,0,0 -ea:-100 -ea:300
-a:8 -ea:300
now,
I chose a buffer size of 1 because I didn't want latency between the
channels and the loops. My kernel has the lowlatency patches installed,
and it set to work mixing the channels down.
It was writing the final file to an NFS volume, but the others were
reading from the same partition, the same directory. The process
misteriously stopped before finishing the file, I didn't thyink much of
it...I thought there was just some wierd interaction in ecasound, one of
those things that just sortta happens...play with ecasound for a
while...you'll get used to it.
I set the debug level to 10, and tried to reconnect the chain setup...not
mutch happened, so I pressed ctrl-c.
oh maybe I DO have this thing.
Here are pongo's last words.

and THAT was all that happened. Some processes that were running still
ran from memory, but when I went down a few hours later to hit the reset
button, the drive was spinning at uneven rates. I powered down the
computer in dim hopes it might cool and then somehow magically recover? :P
DON'T DO THIS AT HOME, IT IS FATAL
MAN, how could this happen?
