Width /Slope/Type
This control changes depending on the type of filter currently in selection, as listed below. For a cut
filter, you have two slopes to choose from the pull-down menu. When a peak/notch filter is selected,
you can use the pull-down menu of preset values, or specify the width within a thousandth of an octave
by typing in a value. There are no settings in this control for shelf filters.
