PROG P3: Filter 3–1: Filter
35
THRU: The sound will output directly, without passing
through the filter.
Frequency (Cutoff Frequency) [000…127]
Specifies the cutoff frequency. Higher settings will raise the
cutoff frequency.
Note: Frequency can be modified by the time-varying
changes produced by EG1, position of the notes on the
keyboard (keyboard tracking), or keyboard dynamics
(velocity). The EG 1 Intensity, Keyboard Track, and
Velocity Sens parameters specify the degree to which these
will affect Frequency.
With some Frequency settings, the volume may
be extremely low or there may be no sound at all.
Resonance [000...127]
Specifies the resonance. This boosts the region near the
Frequency frequency, giving a distinctive character to the
sound. Increasing this value will produce a greater effect.
High settings of Resonance may cause distortion
for some cutoff frequencies or input sounds.
EG1 Intensity [–63…+63]
Specifies the degree to which EG 1 will modulate the cutoff
frequency. This will cause the cutoff frequency to change
over time. Increasingly positive (+) values will produce a
greater effect.
Increasingly negative (–) values will produce a greater effect
in the opposite direction.
Keyboard Track [–2.00…+2.00]
Specifies how keyboard tracking (location on the keyboard)
will modulate the cutoff frequency.
With a setting of 0, keyboard tracking will have no effect.
Positive (+) settings will cause the cutoff frequency to rise as
you play above the C4 key, or fall as you play below the C4
key. With a setting of +1.0, the change in cutoff frequency
will be proportional to the change in pitch. Negative (–)
settings will cause the cutoff frequency to fall as you play
above the C4 key, or rise as you play below the C4 key.
Note: Keyboard tracking is based on the pitch as controlled
by pitch bend, transpose, and modulation sequencer. It does
not reflect pitch changes produced by vibrato or virtual
patching.
Velocity Sens (Velocity Sensitivity) [–63…+63]
Specifies how velocity (keyboard playing dynamics) will
affect the cutoff frequency.
Positive (+) values will cause the cutoff frequency to rise as
you play more strongly. Negative (–) values will cause the
cutoff frequency to fall as you play more strongly
3–1c: Filter B
These are the parameters for filter B.
These parameters are available if filter A Routing is Serial,
Parallel, or Individual.
Type (Filter B Type) [LPF, HPF, BPF, COMB]
Selects the filter type.
This setting will affect the maximum number of voices.
LPF, HPF, BPF: These are the same –12 dB/oct type filters as
for filter A.
For more information, please see “Type/Balance (Filter
Type/Balance)” on page 34.
COMB: In a comb filter (so named for its resemblance to the
teeth of a comb), alternating bands pass and cut the signal,
giving a unique character to the sound. Increasing the cutoff
frequency (Frequency value) will space the teeth of the
comb farther apart, so that more regions are cut.
Link [Off, On]
Causes filter B to operate using the settings of filter A
parameters.
Off: Filter A and filter B parameters can be set
independently.
On: Filter B will operate using the settings of the filter A
parameters. Parameters following Frequency will use the
filter A settings.

EG1 Intensity [–63…+63]
Keyboard Track [–2.0…+2.0]
Velocity Sens (Velocity Sensitivity) [–63…+63]
These are the same as for FILTER A. For details on these
parameters, please see “3–1b: Filter A” on page 34.
