How to Make a 90s Rave Chord in Spire

First I change oscillator 1 to 9 voices and open the wide. Then I immediately change the phase to higher than 30.

Between 0 and 30 it's going to free run the phase. If you put it over, it retriggers at the exact same point. That immediately gives us that analog sound.

I layer this with a simple second oscillator, and add a third oscillator on AM sync with control B down a bit. I add some voices there with widening and some detune.

In oscillator 1 I also increase the density so it's more of a supersaw. Play around with this knob, because it gives you different group voicings.

It can't go without a chorus, so I open that up. Then some X compression, and I roll off a little bit of the lows and boost the mids a bit to add more grit.

Finally I open the all oscillator pitch, change it to a sine wave, open the rate and take the amplitude down. Then some basic reverb and delay.
