Cool patch. Try starting with this:
Oscillators: Two oscillators, both square waves. Give them both unison, with about 4 uni voices, mild detune, and narrow width. Set the second oscillator’s pitch up 19 semitones, and make it louder than osc 1 so those upper harmonics really ring out.
Filter: Band, 24 dB. Set the cutoff around the middle range, so that it’s both round and light. Give it some generous resonance. And if there’s Drive, turn that up to give it some BEEF.
Modulation: Since the modulation pattern changes over a 2 bar period, it’s probably either an LFO that lets you draw in the shape, or a sequencer-style modulator that lets you draw freely. In either case, it sounds like a lot of different length saws, each with an audible upward attack to give it that quick swell-in feel. Then route it to both volume and filter cutoff. The volume mod amount can be generous, but make the filter mod amount pretty subtle.
