hi,this is my set up,i have connected a m/d to a stereo player with a phono plug. then connected a 1/4 inch phono jack to a usb interface connected to my computer,because i have no line in socket only a head phone and mic socket,as i am told the mic socket is only mono.that is why i am using the adapter.i have been informed by another member that yes the wave forms are close and i shoud try zooming in on the wave forms,i havn,t tried this yet.thanks for information
