ditch massive and get razor for reaktor. the sheer nature of the synth just sounds sooooo much thicker than massive
lowpass on filter 1 + comb peak on filter 2
set LFO2 to Phase
assign LFO1 to the lowpass cutoff (duh)
assign LFO2 to the comb filter's phase knob
crank the shit out of the resonance. not all the way, but a lot
the upwards ramping LFOs get you that bubble noise texture
you can use the cutoff on the comb filter to get more variations
just play around with everything else
the key is the low cutoff, high resonance, and the upwards ramping LFO shape. the wavetables don't really matter here. avoid using the more harmonic wavetables.
the main wobble was made all in razor.
