I'm struggling to replicate the deep bass drone in this track. It waxes and wanes through the whole piece, but you can hear it really pop out for the first time at 0:17.
For reference, I'm using Primer with Ableton.
It sounds like the raw waveform is a sinewave, with heavy portamento and legato enabled. But it also sounds like there's some waves of wildly varying amplitude and distortion. I'm trying to use Ableton's Tremolo effect for the amplitude variations, but I'm not sure what filter will give the right distortion effect (Primer's doesn't sound quite right). It also starts doing this weird pulsing thing at 0:46 that I don't even have the vocabulary to describe.
Here's my current attempt:
Any advice?
