Patch Request: NCT U - Baby Don't Stop (Retro Lead)

Hey y'all,

I'm trying to create the retro-sounding synth line that starts at 1:00.

I've spent a couple hours trying to recreate it and I feel like I'm close but I'm missing some X factor to really nail this sound.

See attached my attempts on both Serum and Massive: https://we.tl/t-6ozG85sS3T . Ignore the file names themselves. I think my Serum attempt is closer but they're both missing something.

What am I missing here? First, I think that there isn't another oscillator an octave down so I will likely remove that, but then, when the oscillator is by itself, I'm missing something to get that analog-ish sound.

Anyways, would welcome any comments!
