How to Make Playful Euphoric Leads in Vital

I open Vital, take down the release and set it to one voice, with legato and glide. In basic shapes I find a square wave, but I use one that's a little bit more snappy.

In the warp mode, I add the random amplitudes and find one that works. The overtones will make it sound like a voice.

Then I add some distortion and a bit of detune. Now you can change the amounts with the detune amount and the randomization of the amp.

I take envelope 2 down to a small decay and add that to the pitch. Then I clean it up by adding an EQ in front of the distortion, and add some processing.
