EQ might help but before turning to EQ look at your sounds. Cut down
the sustain, use nice snappy sounds, avoid layering the sounds too
much, cut down any distortion, any effects-simplify.
Good luck. Getting good results with a massive wall of sound is
difficult, but well worth the effort. You are essentially the
conductor arranging for an electronic orchestra.
