I've noticed a lot of synths used in hip hop and modern pop have very little buzz on them. But if I bring my low pass filter down to take some buzz off my synths, they sound like a pillow got put over them.

I know they're not using crazy synths: You can see videos of people working with out of the box synths. And I'm working with common digital synths.

Is this a wave shape thing? Is there a specific sauce to taking "buzz" off a patch without it sounding smothered?

Can give examples if needed but I feel like 90% of people who read this are gonna get what I'm saying just listening to modern pop and then tossing a filter on their favorite digital synth.
