Good way of getting rid of some frequencies is shove a Peq on with the fqs all the way up and the gain all the way down. I just find it helps get rid of some of the distortion on recorded stuff :) Liking this a lot :)
I actually didn't use any synths for this track. I recorded the piano, organ, and bass from my keyboard and used the machiniste for the drums. And I reverbed it a TON. haha.
