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?

If there's not much difference then I won't keep paying the engineer to mixdown my stuff.
