Sad to say that the "analog master" brings up that same old 
misinformation about the 303 filter. 

When a filter has a slope of 345 dB/Oct (fit in any number here) in the
frequency range of interest, then it is perfectly right to adress it as
a "345 dB filter", regardless how many poles and/or zeroes are used.
When you're talking about poles, talk about poles. When you're
talking about slope, talk about slope. If you mix up both concepts,
you can still be right on textbook designs, but not on more exotic
filters.

This should not be in the category of "myth" for someone who is reading
synth-diy for years.

(Your description about "bumpy" and "sound" is perfectly right, so why
not draw the right conclusion?)
