Ok never heard any of them XD

A bit of YouTube :

Personal I would say (A bit of an always right answer Zebra 2 and Zebrify )

And most of what I heard a good Convolution Reverb like HOFA IQ-Series Reverb
or similar https://www.uvi.net/en/software/sparkverb.html would be a great tool for that

Always a Good idea is to look what they use on https://equipboard.com/

That’s a second starting point

Sadly they list only him and only Hardware but

Waldorf Blofeld Module Synthesizer
As Software something with Wavetables would be best VST : Serum, Phase Plant, Or Freeware Vital.
Korg KP3+ Kaoss Pad Dynamic Effects Unit/Sampler
So we need a Multi FX and Sampler
Multi FX :
KiloHearts Toolbox Ultimate ,MXXX , More experimental Izotope VocalSynth 2 (More of a one trick pony, but the Vocoders can create awesome bases with very unique sounds )

And as a Sampler NI Maschine 2 (Software works even without the Device )

Halion 6 or Freeware, CWITEC TX16Wx
