That pitching effect on the synth in the beginning is all to do with the mod env attached to the oscillator pitch. The easiest way, if possible in whatever synths you use, would be to set the mod env to -100; essentially reverse the direction of the mod env's ADSR. Then set the decay to around 450ms and the attack to around 100ms and you've got the effect!

P.S. I recreated the synth in reason's Thor synth, so here's a screenshot for you to translate over to other synths
P.S. This is without EQ, reverb or compressions which you would defo need to add. Let me know if you need the settings for them and ill let you know what I did.
