[VOICE] [EDIT] Element selection
(page 199)
The best way to understand Filter Scaling is by example. For the
settings shown in the example display below, the basic Cutoff
frequency value is 64, and the various Offset values at the selected
Break point settings change that basic value accordingly. The
specific changes to the Cutoff frequency are shown in the diagram
below. The Cutoff frequency changes in a linear fashion between
successive Break Points as shown.

The best way to understand Amplitude Scaling is by example.
For the settings shown in the example display above, the basic
Amplitude (volume) value for the selected Element is 80, and the
various Offset values at the selected Break point settings change
that basic value accordingly. The specific changes to the Amplitude
are shown in the diagram below. The Amplitude changes in a linear
fashion between successive Break Points as shown.
