Yeahh, it was a quick try. I think I got the general quality of sound just way less refined. I'd bet if you use an FM synth (Serum works) and just modulate one wave with another with the modulator up an octave or two from the operator, put a bandpass filter on it, and modulate both the FM amount and filter cutoff with the same LFO you could get pretty close (this is pretty much exactly what I did). From there you'd just need to mess with what wavetables you're using, the amount of modulation, and prob some saturation/small reverb etc to finish it off.
If you end up getting close you should post what you did!
