How could I make a synth similar to the lead in this song?

I've been trying to learn Absynth for the past few weeks and I've been trying to make this synth for a while but I can't figure it out.
Here's a link to the song
I've gotten close by using sine and saw synths (and maybe a fifth) but I can't seem to get it to sound as full and smooth. Does anyone have any ideas? Any help or tips would be awesome!

 

There seem to be a few things going on here.

1. The Bass (lower 2 Harmonics / Octaves) and upper Saw-ish sound are likely to be two seperate synth instances. The bass could be two Sine waves or a sharp-filtered Saw.

I.e. Remember that the song is produced in a more complex chord progression than a mere single synth preset. The bass and upper lead sound are influential into a singular sound.

2. If you are aware of this, then designing the Lead sound as 'maybe a fifth' will just need to factor into the performance rather than the patch, since the chords seem to change.

3. The lead sound itself sounds like it is 3-4 notes, forming a chord. So you could attempt playing chords with just a Saw wave.

E.g. G3, A#3, C4 and D#4 are prominant, forming a chord. As a whole it is about 2 Octaves higher than the bass.

• Add a 12db LP Filter to the Saws, and modulate with an LFO in 4ths or 8ths.
• Try panning the Saws if you can, or running it through a mild spatial processor. There seems to be some Chorus, Short Delay FX or Small Reverberation color to it.

Hope that helps!
