CRACKLING/SLOW MOTION SOUND.... Please help.

hello, im john.

im new to the forum.

There are a couple VSTi that give me this insane crackling noise and time stretching sound.

Reaktor’s Razor plugin does it the worst. I have messed with latency, quality in razor, sound card uninstall/reinstall

it doesnt make that sound with massive, nexus, vangard, ,…etc… Just Razor and sylenth!

any tips or suggestions how to fix this?

thank you!

What kind of system are you running on?

That would definitely help!
OS, 64/32 bit, DAW version, system specs etc
Maybe audio examples as well, if possible?
