How do I create this synth sound?

[UmJammerSully]

I'm new at this but I've been playing around with various free synth VSTs for hours now trying to replicate this synth sound at 0:59:

 

 

I just can't get it quite right.   Can anyone give any tips?

Sounds like a multi-voiced, slightly detuned legato saw wave with some resonance, glide/portamento, and a filter envelope that starts closing after about a second (decreasing cutoff frequency but not resonance). To get that vibrato, try linking an LFO to the pitch with a depth of about 1 semitone. The right choice of filter, and the right amount of resonance and vibrato would probably help too.
