Why are some of the SAME filters so DIFFERENT?

This has always driven me crazy but it doesn't seem right.
I KNOW some filters are simply better than others. But if you understand what I'm saying you'll see why this isn't what I'm talking about.
All of FL's native filters sound like this (on lowpass) Massives (again LP) and Reasons LP filter among many others.
Vangards LP filter doesn't, V-Stations doesn't, and many others.
But if you open/close the LP filter in something like FL's native ones you get sort of a dry/straight cut off affect.
If you open/close the filters in Vangard or V-Station you get that effect BUT you also get a glossy bubble like sound. Its hard to explain. I know some filters just sound sharper and better quality, but this is like something some LP filters just do or don't & its confusing.
Like you can open an LP12 filter in Vangard, than shut its filter off and use FL's native LP12 filter setting, and you get 2 completely different effects opening/closing them.
Does anyone know what I'm talking about? Why do some filters do this and others don't? And is there a name for it?
I may have confused some people but its a really noticeable difference, if I have to post examples I will. |

| Its just different algorithms they used mate... thats why some filters are soled after over others. |

| Vanguard and V-Station have filter envelopes connected to their filters in most (or all) patches. |

| Sounds like resonance to me. |

LPFs use phase cancellation to acheive the effect. Well analogue ones do anyways. Phase cancellation can be conducted in plenty of different ways and there might be another method to use apart from phase cancellation.
The frequency cut off curve may be different in one filter to the next.
You can see the difference in the curves by pushing some white noise through various filters setting the cut off frequency the same, then have a look at the output in a spectrometer. You will notice that they are shaped completely differently. |

I'm getting a lot of different answers here and I figured that might happen unless I show examples.
I considered envelopes but when I open basic saw waves in z3ta or Vangard w/out filter envelopes it still does the effect I'm talking about.
As far as different algorithms lol I'm looking for something more specific.
The phase cancellation and frequency curve sounds like that *may be it. More in particular the phase cancellation because it does sound like the filtered sound is actually getting somewhat disorted, but in a good way that adds a unique character to the sound.
I will get an example of 2 of the same sounds, with no envelopes, going through 2 different filters so you can see exactly what I'm talking about.
Because what I'm actually looking for is a vst filter that replicates this affect as good or even better (if possible) as vanguard/z3tas/v-stations filters. May not seem like that big a deal but you'll see when I get it up. |

Haha I feel like an idiot. TGL had it. It WAS the filter envelopes.
I didn't realize untill I played with the sustain part and the effect became noticeably punchier.
They really add such a beautiful character to the sounds. Thanks! I'll try not to have such newbie questions in the future. Should be ashamed of myself lol |
