Your having trouble writing a melody. It sounds like you want key E.
I would turn on the Matrix after designing a voice and build a mode.
Make all the notes E or F and THEN start writing a melody.
If you listen starting on C, all your melodies will sound the same.
1) Thor Bass
3) MClass Mastering Suite - Equalize Maximum Lows
4) Choice of Scream4distortion.
That will get you the bass you want.
Use the bass to write a melody and then try to harmonize with the drums. If your smart, plan notes so that they BUILD chords when they overlap.
