Tried to repro this one for a while, I am close but not exactly right. I wondered what you would suggest to repro it. I found myself close with two detuned sinewaves in serum and some portamento on the chords attack.
Damn. This song is good. I think it’s a filtered saw.
How It’s Made
Oscillator: Saw wave, 3-voice unison with low detune and even blend
Filter: MG Low 24, Cutoff at 1199 hz, Res at 23%, Drive at 63%, Level at 21%
Modulation: Amp envelope with Attack at 126 ms, Dec at 2.44 s, Sus at 0. LFO routed to Osc A level, with a Tri waveform, fast rate, and very little modulation amount, so that it just creates a subtle wobble
Portamento: Knob at Noon, Curve curved upward so that the pitch bend starts quick but slows into the destination note. Though the bending pitch may be triggered manually, since it doesn’t come in on every note.
