Hello all,
I am struggling with multicannel-files and loop-devices.

For understanding my problem:
Everything works fine without a loop device as shown here:
ecasound -n test.ecs -f:s24_le,16,48000 -i 16Channel.wav \
-a:1 -chorder:1.00 -eadb:-70.00,0.00 -chcopy:1.00,2.00 -epp:40.00
-chorder:1.00,2.00 \
-a:2 -chorder:2.00 -eadb:-65.00,0.00 -chcopy:1.00,2.00 -epp:45.00
-chorder:1.00,2.00 \
...
-a:15 -chorder:15.00 -eadb:-80.00,0.00 -chcopy:1.00,2.00 -epp:65.00
-chorder:1.00,2.00 \
-a:16 -chorder:16.00 -eadb:-60.00,0.00 -chcopy:1.00,2.00 -epp:60.00
-chorder:1.00,2.00 \
-a:all -f:s24_le,2,48000 -o stereo-mixdown.wav

But now I want to have a submixer for the drums that occupies 6 channels.
I tried and tried with no success.

It should be possible like that. But i had no success:
ecasound -n test.ecs -f:s24_le,16,48000
-a:1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 -i 16Channel.wav \

-a:b11 -i loop,drums -chorder:1.00 -eadb:-70.00,0.00 -chcopy:1.00,2.00
-epp:40.00 -chorder:1.00,2.00 -o loop,CD \
-a:b12 -i loop,drums -chorder:2.00 -eadb:-70.00,0.00 -chcopy:1.00,2.00
-epp:40.00 -chorder:1.00,2.00 -o loop,CD \

-a:b14 -i loop,drums -chorder:4.00 -eadb:-70.00,0.00 -chcopy:1.00,2.00
-epp:40.00 -chorder:1.00,2.00 -o loop,CD \
-a:b15 -i loop,drums -chorder:5.00 -eadb:-70.00,0.00 -chcopy:1.00,2.00
-epp:40.00 -chorder:1.00,2.00 -o loop,CD \
-a:b16 -i loop,drums -chorder:6.00 -eadb:-70.00,0.00 -chcopy:1.00,2.00
-epp:40.00 -chorder:1.00,2.00 -o loop,CD \
-a:L1,R1 -i loop,AB -efh:70.00 -o loop,LR \
-a:L2,R2 -i loop,CD -efh:70.00 -o loop,LR \
-a:LR -i loop,LR -f:s24_le,2,48000 -o stereo-mixdown.wav

I used -d and -ddd ... but the behavior is completely not the expected.
The added effect -efh for L1,R1,L2,R2 is just for demo. Some
stereo-hall-effect will be used later.
I played around a lot, but nothing helps.
Maybe someone has had success with such a setup?

Thank you in advance,
Oliver
