On Deny, I used EQ throughout the track to separate the synths and many vocal tracks. I used the TDR Nova plugin as a dynamic EQ to help with this by cutting out the frequencies that were competing.
In order to get a good bass sound, I used a Ana 2 midi plugin for the base sound then added a Decapitator and DevilLoc Plugins in order to give the bass more character. I used the TDR Nova plugin again on the instrument to help create more space for the vocals. I also wanted to try to separate the kick and bass, so I cut out the fundamental freq of the kick in the bass and vice versa.
