Put in on Legato mode, put the number of voices on say 16.
Put the first Osc on the Sinewave with Frequency modulation. Set it at the bottom of the FM spectrum then assigned it on the router to say Evelope 2.
Put a rather long attack on it and set the sustain to full.
Assing the waveform to envelope 2 btw.
On Osc 2 put it at a wave form that you think is right. also assign the waveform to envelope 2 but put the level at a small amount.
Also put it in Unison mode.
Assign a cutoff filter to envelope 1 and put a long attack with full decay.
Then assign a cutoff filter to an LFO put it at 1/16ths and automate the level of which the lfo affects the cutoff.
Its a basic template to go on...someone else will be able to give a better explaination as I hate making these sorts of sounds
Not much idea tbh but it almost sounds like the lfo is cranking the resonance on a band pass filter rather than the cutoff. Or it could be different layers of audio..?
Yeah band pass with a 1/12 with an envelope on the LFO's amp. Can't get the specific waveform in massive but chuck a couple of your fav ones ina nd you'll have something consistent with your sound.
