How do I make this synth?

[Grayburg]

dat pop synth

i can guess it's primarily a sine wave with some portamento.

anything else to make it sound less.. basic?

Has some some vibrato and light delay too, a lot of making a lead like this sound good is just articulation

[zircon]

Yep, just a raw sine wave with vibrato (LFO -> pitch), portamento and lots of pitch bends. If you have an additive or wavetable synth you could add a bit of extra interest by using a triangle or sine-tri waveform which will add a few more upper harmonics.

seems to make sense physically
