I also wanted to draw attention to this problem, except that I don't have such good proof, only my auditory impression. The resonance of the SVF LP, despite a Q of 0, is clearly audible. And just like the ladder filter, the Moog filter also makes the signal significantly louder overall.
I also noticed that the SVF BP and Notch Filter display in Scriptnode is broken.
(Is the forum actually the right place for bug reports?)
