I feel like someone could generate sounds like this by learning DSP synthesis techniques and dogmatically treating aliasing as a feature instead of a bug.

Edit: to be clear, I like the sounds. I just think DSP beginners learn early to watch out for aliasing in their algos and have the side effect of rejecting timbres that are in any way reminiscent of aliasing from their toolset.

Check out Noise Engineering. Their oscillator modules use a variable speed sample rate so aliasing changes frequency proportionally to the note being played.

So rather than keeping a fixed sample rate with dynamic oscillator pitch (and having to account for bandlimiting the oscillator dynamically as it changes pitch) the oscillator is at a "fixed" frequency but the internal sample rate is changed to get it to play at your desired pitch. This way the aliasing is tuned to the harmonics of the oscillator no matter what pitch it plays.

They also make VST plugin versions of some of their modules but I don't know if they emulate the variable sample rate behavior.
