Multiple feedback bandpass based EQ

Has anyone done this project:

There are two implementations:

In-out stage:

The bandpass module:

Different layout and mixer:

Corresponding mfb module:

I prefer the second one, where we can have single opamps before and after the mfb modules.

I am trying to simulate both, using the values and the calc tool in the website, but neither the frequencies, nor the cut/ boost gain matches with the values of the elements 🙁
