How to make this simple pitch down effect?

Hi Virus TI users. How do I make this effect just BEFORE the melody starts to kick in? its some kind of pitch down technique. I've tried to fool around with both LFOs and pitch envelopes but doesnt get it to sound right, eventhough it sounds pretty simple to do.

Any advice would be appreciated.

It can be heared @ 26seconds in this clip. It's just a simple pitch down just before the lead kicks in.
If you get what I mean?

Is it the same synth or an other instance of the effect that is added after before the lead?

Any simple way to make this? Especially using the virus ti (since Im using it).

Thanks.
