Filter Scale
This controls the Filter Cutoff Frequency according to the positions of the notes on the
keyboard. You can divide the entire keyboard by setting four Break Points, and assign different
Cutoff Frequency Offset values to these Break Points. The Cutoff Frequency changes in a
linear fashion between successive Break Points.
Table 1 and Figure 30 show an example in which the basic Cutoff Frequency value is 64 and
the various Offset values of the Break Points change that basic value accordingly.
