PRO EDIT parameters (INST FILTER)
Filter Type
Selects the type of lter.
OFF No lter is used.
LPF
Low Pass Filter. This cuts the
frequencies in the region above the
cuto frequency (Cuto Frequency).
Since this cuts the high-frequency
region, the sound becomes more
mellow. This is the most common lter
used in synthesizers.
BPF
Band Pass Filter. This leaves only the
frequencies in the region of the cuto
frequency (Cuto Frequency), and
cuts the rest. This can be useful when
creating distinctive sounds.
HPF
High Pass Filter. This cuts the
frequencies in the region below the
cuto frequency (Cuto Frequency).
This is suitable for creating percussive
sounds emphasizing their higher tones.
PKG
Peaking Filter. This emphasizes the
frequencies in the region of the cuto
frequency (Cuto Frequency). This can
be used to portray the resonance peak
of a drum.
LPF2
Low Pass Filter 2. Although frequency
components above the Cuto
frequency (Cuto Frequency) are cut,
the sensitivity of this lter is half that of
the LPF. This makes it a comparatively
warmer low pass lter. This lter is
good for use with simulated instrument
sounds such as the acoustic piano.
* If you set “LPF2,” the setting for the
“Resonance” parameter will be
ignored.
LPF3
Low Pass Filter 3. Although frequency
components above the Cuto
frequency (Cuto Frequency) are cut,
the sensitivity of this lter changes
according to the Cuto frequency.
While this lter is also good for use with
simulated acoustic instrument sounds,
the nuance it exhibits diers from that
of the LPF2, even with the same TVF
Envelope settings.
* If you set “LPF3,” the setting for the
“Resonance” parameter will be
ignored.
Cuto Frequency
0–1023
Selects the frequency at which the
lter begins to have an eect on the
waveform’s frequency components.
With “LPF/LPF2/LPF3” selected for the
Filter Type parameter, lower cuto
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 Cuto
Frequency setting. This can be useful
when creating distinctive sounds.
With “HPF” selected, higher Cuto
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
Cuto Frequency setting.
Cuto Velocity Curve
FIXED, 1–7
Selects one of the following seven
curves that determine how keyboard
playing dynamics (velocity) inuence
the cuto frequency. Set this to “FIXED”
if you don’t want the Cuto frequency
to be aected by the keyboard velocity.
Velocity Sens
-100–+100
Specify this if you want keyboard
playing dynamics to aect the lter
envelope depth. Specify a positive “+”
value if you want the lter envelope to
apply more deeply as you play more
strongly, or a negative “-” value if you
want it to apply less deeply.
Time 1 Velocity Sens
-100–+100
Specify this if you want keyboard
playing dynamics to aect Time 1 of
the lter envelope. If you want Time 1
to be speeded up for strongly played
notes, set this parameter to a positive
(+) value. If you want it to be slowed
down, set this to a negative (-) value.
Time 4 Velocity Sens
-100–+100
Specify this if you want key release
velocity to aect Time 4 of the lter
envelope. If you want Time 4 to be
speeded up for quickly released notes,
set this parameter to a positive (+)
value. If you want it to be slowed down,
set this to a negative (-) value.
Time 1–4
0–1023
Specify the lter envelope times (Time
1–Time 4). Higher settings will lengthen
the time until the next cuto frequency
level is reached. (For example, Time 2 is
the time over which Level 1 will change
to Level 2.)
