Great! But how would this be achieved? Here is what I tried:
ecasound -c -a:all -f:s24,2,48000 -a:1 -i raw/Vocals.wav \
         -a:2 -i selfproc/lead3.wav \
         -a:3 -i:loop,SCin -o:loop,SCout -eli:1427,0,75,100,-20,10 \
         -a:1 -o:loop,SCin -a:2 -o:loop,SCin -chcopy:2 \
         -a:4 -i:loop,SCout -epp:50 -o:jack,system

But ecasound claims it is unable to create a valid chainsetup from this.
It seems right to me. What am I missing?

Cheers,
S.M.
