Hi, I have Emu 0404 audio/MIDI interface and tried to set up my equipment (to connect my keyboard and computer through the interface). Now I met my first problem. When I am doing audio recording in a way that my jack plug comes out from the output of the instrument (left and right) and goes into the EMU interface Mic/Hi-Z/Line input. However it also has left and right, so it records on only one side (left or right). To solve the problem do I need two jack cables, one goes out from the instrument from right output into the right input of the interface and the left goes into the left? Or how can I record audio stereo? Or if I buy a MIDI cable can I record audio as well?
