It is 2 12 Db filters that can be run in serial or parallel. There is a spacing control that can offset the 2 peaks from each other. That is it. It is either in Notch, BP, HP or LP. There is no morphing between them.
Fair enough - but I am still quite confused about how the SVF should be approached.
My understanding is that the SEM filter really has all 3 modes (LP, BP/notch and HP) active at all times, and the morphing just blends between them in the output. Clearly the Moog One's SVF is not designed that way.
The One really has 3 filters, 2 in the SVF and 1 Ladder. According to the manual, the 2 filter elements in the SVF are identical and from the manual: "their arrangement and interaction is determined by the choice of NOTCH, Bandpass (BP), High Pass (HP), or Low Pass (LP) Modes on the Front Panel, and by other parameters located in the Filter MORE page."
Then there is serial/parallel local to the SVF's 2 elements AND serial/parallel between the two filters. The latter makes sense, since you can put them in different modes, but the former? What is the point of two LP filters in serial mode unless you can change the mode of one or the other? If the only difference is the cutoff, then one filter is going to do big fat nothing.
If, on the other hand, each of the 2 elements could be set to its own mode (or at least the inverse of the other) then with spacing you could pretty much emulate all other continuous filter configurations, including blending towards and away to/from LP/BP and HP.
I know I am missing something, but as it is the manual and the information I have been able to find has only confused me more.
