Where would I even start to make a Buku sounding lead?

I’ve been trying for a while now to try and achieve something similar to Buku’s sound, but I just can’t get it. Like at all. I’m sure it’s something pretty basic, but maybe I’m missing something. Anyone have any idea?

Sound(s) start at :57 seconds in. https://www.youtube.com/watch?v=w07x32cMhUQ

something about his sounds have always screamed vocoder to me.

Sounds like a super saw with a little bit of resonance. Play with detune/ spread/ vibrato then parallel processing (saturation, chorus, reverb etc.,)

Then MAYBE… If it needs it do some multi-band compression to bring out some of the highs without making it too harsh

Hope that helps
