why did i came across this cause about ETCH there the filter looks like this

It says 2 pole, though. That's 12 dB/oct, not 6.
exactly.

Caine, if you didnt already know it, there are two ways typically used to describe the slope of a filter.
One is dB/oct, and unless the filter topology is very unusual, the figure is a multiple of 6 eg 6dB/oct, 12dB, 24db/oct.
The other is the number of 'poles' the filter has, ie 1,2,4. (You'll often see this combined with the filter type as a shorthand eg something like 4LP, 2HP, or just 4L, 2H. The latter is how Etch does it). Each pole contributes to 6dB/oct of the slop, so a 3-pole lowpass filter has an 18dB/oct slope.
Etch only has 1-pole filters as part of some of the 'combined' filter types, ie 1N+2P)
An idiot on Set Theory:
"In some cases there is an object called red that contains everything that is red. In much the same way a pot is a plate."

It is a bit confusing because the OP sets the title as for EQs but then talks about synth filters.

The only EQ I know of with 3db/oct high and low pass filters too.

kirchhoff eq does smooth morphing from 0db/oct up to 96db/oct
