i posted earlier but wanted to have all my bases covered. i am trying to mix a soundtrack for a student film i am doing. i am going from a recorder to the four track. all the music is prerecorded on tape. whenever i record on to one of the four tracks, that seems to go fine. everything appears right. when i try to mixdown, i get no noise, no music. what is the problem? could it be the connections or perhaps the actual tape the music is on? the vu meter on the recorder is not reading all that much--at the far left of the negative yellow is that too quiet to record adequately? i have big time problems so any advice would be great. thanks
