Spencer & Hill - Just Dance Now (LA Riots Remix)
It comes in at :45, the high synth on top of the bass, its obvious.
I’d be interested in the bass sound too, but it sounds like they just sampled the original bass and put a lot of distortion on it.
sounds like octave super saws.
plenty of sidechain compression and a bit of overdrive/distortion.
you will also need to assign Pitch to pitch bend or mod wheel to get the pitch dives.
