I am using a Layla card, and i am trying to patch in effects on some of my wave files...I do not use an external mixer...only the mixing software that came with Layla......what I am doing is patching the track from outputs 1 & 2..to the effects rack....and then back into inputs 1 & 2..and recording on cool edit on a seperate track...the problem is i get a very deafening feed back if i attemtp to raise the input or output levels on my mixing software......Am i doing something wrong (creating a feedback loop?) is there a better way to patch an effect than the way i mentined using this setup?? It seems like an easy thing to do...but so far I am going deaf listening to the noise i am making....thanks in advance Heat
