I imagine that this extremely flexible filter plus the huge additive features are the main reasons of the CPU hog from Spectral. It was certainly a drawback at the moment of the first version four or five years ago, but now that the computers are quite faster than in 2013 it is certainly a problem which disappears now. It's too bad that Peter will not profit financially of that improvement of the CPUs of today (I guess that one of the reasons of his stop today is because Linplug was less and less money-making along the years). With Spectral he has worked for the future (the other companies too of course)... and now he leaves.

What's the purpose/result soundwise? Usually the more poles, the more "muted" a LP filter sounds. Except for Saurus if I remember correctly
As just mentioned that drawable filter in Spectral displays the semitones in x-axis (with 12 semitones = 1 octave) and dB in teh y-axis so you coudl measure the usual dB/Oct value for the "steepness" of the filter.
Anyway the drawable filter in Spectral is not really similar to a hardare filter that normall used multiple values of 6dB/oct like e.g. 6, 12, 18, 24 etc.
I Spectral you coudl also use values that are not multiples of 6 like e.g 10 dB etc.
A higher "Steepness" of a Lowpass filter at the same Cutoff value results in less high frequency content which could be especially helpful for Bass sounds (and also for Synth Horns liek in my own patch i mentioned above).
A "formant filter" usally consists of many Banpdpass filters with a fixed Cutoff and those Bandpass filters usually need to be very steep to not have too much overlapping of the different filter bands.
With the drawable filter in Spectral you could create a very steep Bandpass filter and also a kind of formant filter with mu8ltiple bands.
You could also create a complex filter that does not correspond to anything found in a hardware synth.
I could almost say that Spectral is a synth which would have better been released today than in 2013...
