I enjoy the tone of no.3, but I also like the speed of the LFO on no.5. especially in the build up. no.3 gets my vote though. I think putting a little stereo space on the bass channel would be a good idea for this, give it a lil room to breath and set it apart from the drums and melody thus making it more of a focal point in the track. I have to admit, its definitely my favorite track of yours to date.
What are you using to compose..?
