Try to creat flames old sound

holy shit, your synth track is totally in a different key signature from the guitars! your synths are in the key of A# minor, and the guitars are in B minor.

if the keyboard tracks are programed in a sequencer, select all the notes and move them up a half step! if you are new to music and don't know what key signatures are, it's best to start learning now! Google "key signatures"
