Actually it's acting as the front-end to the 1023 band EQ.  The curve is
splined to 1023 separate frequency bands.  The same thing happens with
the 31 band EQ it's just that you don't have the same amount of control.
With the HDEQ you can cut or boost *very* narrow bands.  I have a
recording of a band I was sitting in with in Ft Lauderdale a few years
back.  When we recorded there was a very narrow band of feedback that
would show up occasionally.  I used the HDEQ to cut just that
frequency.  I couldn't have done that with the 31 band EQ and, since it
was just a live stereo recording there was no mixing going on.  One of
the nice things about using Ardour/JACK/JAMin is that you can hook up
Ardour->JAMin->Ardour and run tests while tweaking both the mixing and
mastering.
