Some people are saying that I should compress each track differently. If so, I'm very inexperienced and am afraid I wouldn't do it right.

Bass guitar is usually what needs it most. The bass instrument is a metallophone but sounds an octave higher than a proper bass guitar. I'm also not using guitar, synth pads or piano so I'm inclined to ignore EQ entirely since those are what traditionally need it and I wouldn't know what I was doing anyway.

So far, I listened to how each instrument sounds when playing back in Cubasis and adjusted the levels in the midi track mixer so that it's like in a live performance with each instrument panned where it would be on the stage never pushing anything farther to the left or right than 50.
Would you do it differently?
