Filter
A filter is a circuit or processor that modifies tone by blocking or passing a specific frequency
range of the sound.
Filters work by allowing portions of the signal lower or higher than a given frequency to pass,
and cutting the remainder of the signal. This given frequency is referred to as the Cutoff
Frequency. You can produce a relatively brighter or darker sound depending on how you set
the Cutoff Frequency.
By adjusting the Resonance (which boosts the level of the signal in the area of the Cutoff
Frequency), you can produce a distinctive "peaky" tone, making the sound brighter and harder.
On the tone generator block of the Electronic Musical Instrument, the sound signal output from
the Pitch unit is processed by the Filter unit.

Cutoff Frequency
Determines the Cutoff Frequency for the Filter, or the central frequency
around which the Filter is applied.
The tonal characteristics of the Voice and function of the Cutoff Frequency
differ depending on which Filter Type is selected (see Chapter 1-2-5 Filter
Type).
