Modifying the filter cutoff or resonance does NOT change the noise timbre. There may be a slight relationship between changing the resonance and that triggering the the noise. But only very slight.


But you'll agree that in your example recording, the noise has more high frequency content when the note is playing, than later when the note dies away?
If not affected by the filter directly, then there may be some relationship with the note envelope
