What's this sound?

Help wanted. I don't know the first thing about synth sounds. The vast majority of the music I record is done on real instruments or at least sample libraries of real instruments. I'm recording a track for an artist who wants a certain sound in their track. I wouldn't have the first clue as to where to look. Wouldn't know what category of synth sound it is. I don't know my Saw from my Sine or Square from my Poly. Don't know what any of that means so I'm finding it really difficult finding what I'm after. 
 
Any chance some kind synth expert could point me in the right direction. All I hear is it sounds a bit 80s but that doesn't narrow it down when it comes to synths I know. Could someone tell me "oh yes that's this type of sound" or even better say if I have that sound in any of the included SONAR synths. Or if not what to look for in free downloadable synths. 
 
You'll hear it on Spotify or wherever you listen to music. It's on the track "It's All Good" by Superorganism. It's the lead line between 0:35 and 0:52. 
 
Thanks in advance.

Hi Mike
 
Thanks for this answer. Remember I haven't the first clue what I'm doing here.
I'm in z3ta+. I've chose Vintage Saw 2 for the first two oscillators (whatever that means) and turned the others levels down. One is an octave down. Sounds promising, however the is an arpeggiator going on and I don't want it. How do I get rid of it? Don't know my way round z3ta or what most of the things mean. Can't find anything that says arpeggiator. What am I looking for?

Hey there,
   It's hard to know exactly what's going on without seeing it, but if disabling the ARP causes bizarre behavior, there must still be some settings hanging around from an old patch. Make sure you're starting from a fresh program (Go to "Program->Initialize"). In z3ta, the Arpeggiator is (I'd say somewhat confusingly) grouped with the Low Frequency Oscillators. In the top right pane of the interface, far right button should be "AR". Click that and make sure pattern is set to off.
 
You'll also need to make sure your oscillators are routed to the filter that you're using. In each oscillator there's a slider for "Bus" - make sure it's all the way at the top if you're using filter #1. 
 
If it still sounds funky, it could be because Zeta is defaulting to a low-quality mode to save CPU. Mine defaults to draft-quality, which does cause it to sound pretty gritty. To fix that go to "Options" and make sure both Real-time and Render Quality are set to at least 1.0, or even 2x oversampling.
 
That ought to do it...
