Explanation
Selects the type of filter.
MEMO
TVF stands for Time Variant Filter, a filter
that lets you specify in detail how the
frequency components of the sound
change over time.
If you select VCF, the polyphony will be
lower than if you select TVF.
No filter is used.
Low Pass Filter.
This cuts the frequencies in the region
above the cutoff frequency (Cutoff
Frequency).
Since this cuts the high-frequency
region, the sound becomes more mellow.
This is the most common filter used in
synthesizers.
Band Pass Filter. This leaves only the
frequencies in the region of the cutoff
frequency (Cutoff Frequency), and cuts
the rest. This can be useful when creating
distinctive sounds.
High Pass Filter.
This cuts the frequencies in the region
below the cutoff frequency (Cutoff
Frequency).
This is suitable for creating percussive
sounds emphasizing their higher tones.
Peaking Filter.
This emphasizes the frequencies in the
region of the cutoff frequency (Cutoff
Frequency).
You can use this to create wah-wah
effects by employing an LFO to change
the cutoff frequency cyclically.
Low Pass Filter 2.
Although frequency components above
the Cutoff frequency (Cutoff Frequency)
are cut, the sensitivity of this filter is half
that of the LPF.
This makes it a comparatively warmer low
pass filter. This filter is good for use with
simulated instrument sounds such as the
acoustic piano.
* If you set "LPF2, " the setting for the
Resonance parameter (p. 42) will be
ignored.
Low Pass Filter 3.
Although frequency components
above the Cutoff frequency (Cutoff
Frequency) are cut, the sensitivity of this
filter changes according to the Cutoff
frequency.
While this filter is also good for use with
simulated acoustic instrument sounds,
the nuance it exhibits differs from that
of the LPF2, even with the same TVF
Envelope settings.
* If you set "LPF3, " the setting for the
Resonance parameter (p. 42) will be
ignored.
Each setting simulates the operation of
an analog synthesizer's LPF. In particular,
MG, JP, and P5 are types that are suitable
for reproducing synthesizer sounds of
the past.
* This is valid when the Filter Type is "VCF. "

Explanation
Selects the slope (steepness) of the filter.
For VCF, you can choose -12, -18, or -24.
For TVF, only -12 or -24 can be selected.
If Filter Type is TVF, the following
limitations apply.
5 You can specify only -12 dB or -24 dB. If
you specify -18 dB, the sound generator
operates internally with the -12 dB
setting.
5 If you specify -24 dB, the polyphony will
be lower than if you specify -12 dB.
Emphasizes the portion of the sound in
the region of the cutoff frequency, adding
character to the sound. Excessively high
settings can produce oscillation, causing
the sound to distort.

Use this parameter when changing the
resonance to be applied as a result of
changes in playing velocity.
Specify a positive "+" value if you want
resonance to increase when you play
strongly, or a negative "-" value if you
want it to decrease.
Specifies how the TVF Depth of LFO1
is affected by the program's Modify Vib
Depth.
Specifies the cutoff frequency of the -6 dB
high-pass filter.
* This is valid when the Filter Type is "VCF. "
Selects the frequency at which the
filter begins to have an effect on the
waveform's frequency components.
With "LPF/LPF2/LPF3" selected for the
TVF Filter Type parameter, lower cutoff
frequency settings reduce a tone's upper
harmonics for a more rounded, warmer
sound. Higher settings make it sound
brighter.
If "BPF" is selected for the Filter Type,
harmonic components will change
depending on the TVF Cutoff Frequency
setting. This can be useful when creating
distinctive sounds.
With "HPF" selected, higher Cutoff
Frequency settings will reduce lower
harmonics to emphasize just the brighter
components of the sound.
With "PKG" selected, the harmonics to
be emphasized will vary depending on
Cutoff Frequency setting.
