Ozone EQ bell filters

Hi everyone,
I was trying to figure out the difference between Proportional and Peak bell filters of the EQ module within Ozone 7.
The Peak bell should be a constant Q, while the other a proportional one (and both symmetrical). Looking at the shape of the bells, however, this difference can't be noticed. So I filtered a pink noise inspecting the result with SPAN (the results in the attached images).
As you can see from the images, while the behaviour of the Proportional Bell is the expected one, the Peak Bell doesn't resemble a constant Q bell.
Anyone has further information?
Thanks a lot,

Daniele

Very helpful thanks!
It would be nice to replicate the results but a mac version for VST analyzer doesn't exist.
But with white/pink noise the behavior should be the same right?

This is the right tool for me, thanks!
I proceeded analyzing the Ozone 7 Equalizer with it, but the results still don't convince me (attached image)...
Any hint?
Thanks a lot,

Daniele

looks fine to me. the bandwidth of the proportional Q peak filter depends on the gain that is applied. the more gain is applied, the smaller the bandwidth is...as shown in the figures.
