Too many layers in one synthbass. There are 2 basic synthbass at 0.40 seconds. sub oscs are common, but oscillators at mid and treble frequencies are different. In short, I say mid bass and side bass here. In mid bass and side bass, one of the oscillators is an osc with analog thruzero fm feature. the other is a fully digital thru zero fm oscillator. I made this mainframe by programming it in analog logic. but there are still some extra moves. I cut them out of some of my synthbass jams and inserted them into the song.
