Question about loops

Hi,

I'm building a Multiband Limitter for FM transmitter with ecasound.

My command line (a pipe to Ices2)
LC_NUMERIC=POSIX ecasound -s:ctest2.ecs -dd -D (-q)

With ctest2.ecs :
-z:mixmode,sum -f:24,2,96000 \
-a:IN -f:24,2,96000 -i alsahw,0,0 -o loop,1 -o loop,2 -o loop,3 \
-a:LOW -f:24,2,96000 -i loop,1 -el:bandpass_iir,1500,3000,2 
-el:fastLookaheadLimiter,0,-0.5,0.060 \
-a:MED -f:24,2,96000 -i loop,2 -el:bandpass_iir,7500,7000,2 
-el:fastLookaheadLimiter,0,-4,0.050 \
-a:HIG -f:24,2,96000 -i loop,3 -el:bandpass_iir,14000,6000,2 
-el:fastLookaheadLimiter,0,-12,0.030 \
-a:LOW,MED,HIG -f:16,2,96000 -o stdout

What I want to do is to spleet the output of chain 'IN' to the 3 chains 
'LOW' 'MED' 'HIG'.

This setup start the engine, but I've got warning :
(eca-chainsetup) WARNING: Output "loop,1" is not connected to any chain. 
(3.2-DISCON-OUTPUT)
(eca-chainsetup) WARNING: Output "loop,2" is not connected to any chain. 
(3.2-DISCON-OUTPUT)
And only the 'HIG' chain works.

I know the rule :
1 chain has one input and one output and how to write "-o loop,1,2,3" ?

Re: Question about loops

Hi!
  try something like:
-a:IN1,IN2,IN3 -i jack_alsa \
-a:IN1 -o loop,1 -a:IN2 -o loop,2 -a:IN3 -o loop,3
...
Then continue with your LOW, MED, HIGH chains.
  Kindest regards
