Curious about the synthesis in "Wing" by False Noise. The main synth that plays right at the first second of the song.

Here's the song I'm talking about (0:00): https://youtu.be/1H-9zZwQffM?si=\_LMbl83v7qx\_jkVI

The main question isn't really "how to make this", more like, how's it even achieved? I suppose post-processing plays a role here. Concrete details aren't important, i just really want to know what's the process of creating something like this goes like. I don't want to recreate the synth completely, i think i just want to know how it works and understand the main idea.
