Can someone help me out ...I am new to this and I bought a few toys t fiddle with. But from what I am reading in differnt books is that ...Say the drums, base, vocals and Keyboards all have there sounds confined to a certain freq range. Kind of shelving frequencies so as not to step on what is going on around it. Can someone give me a basic frequency chart as to what frequencies to stack what is Example Drums 100hz to 900hz. And if this is all wrong please give me some tips.
