There’s a certain VA algorithm on it that allow morphing between waveforms, and changing the pitch of one of the 2 ocilators at the same time. Sounds absolutely bangin. Could be that too.
It sounds like the EMX1 mod delay, then a nice reverb (as the EMX1 reverb is terrible)
I could be wrong.
As @J3RK pointed out, fairly easy to do with almost any synth.
Uneven step length sequence helps too, 7 against 16 for example.
I somehow knew the answer would be Korg before playing the video. Any time in the last 20 years someone has wanted not just any cool bleepy sound but a SPECIFIC cool bleepy sound the answer has been Korg. I ended up with an MS2000 for the same reason.
