@hyperphonias For that particular knob I wouldn't use an image. I'd do it with look and feel.

But this is what you are asking for - https://www.wavesfactory.com/blog/posts/strip-generator/

@griffinboy the way you could make this i think its with a bandpass and a gate something like this. I made a denoiser plugin only using with nodes and it worked so yeah. but i do not know how i can make the bandpass filter and still hear the other frequencies

@orange ok thanks, its sounds like a depth, I just had to remove the clear because i don't know why but it was kinda "glitching". but without it works better
