How to Make a Classic Euphoric Lead in Sylenth1

I open the mono legato to make sure it glides. Then I get the random LFO, open the gain and the amount all the way, open the rate all the way and put it on free, so we work with hertz.

Then I take down the amount just so it doesn't sound too screechy.

Then I get pitch AB for a pitch attack. Open the decay and take down the sustain, and now you get that pitch attack.

I open the clip distortion to around 60 to 70% to get that square-y sound.

In part B I enable another saw wave with three voices. Increase the detune and keep it on retrigger, or disable it. Then I open a noise and take the volume all the way down, and change the mix of B so it blends with the original saw a bit better, because the white noise has a lot of high frequencies.

Finally I add a delay with the left on 1/2, the right on 1/4, the width all the way open and ping pong on.
