The Filter & EG Edit Parameters
Please note that a number of FIL&EG EDIT parameters which are available
in the VOICE sound module mode are not available in the VL-XG sound
module mode (page 28). The parameter numbers are therefore different in each
mode.

 Filter & EG Edit Parameter Descriptions
The small parameter numbers in parentheses apply in the VL-XG sound module mode.
Filter03(03): FilEG Dept
•Filter EG Depth
•Settings: -64 … +63
The “FilEG Dept” parameter determines to what
degree the amplitude /filter envelope generator (see
“08(06): Attack Time”, “09(07): Decay Time”, and
“10(08): ReleaseTime”, below) affects the filter’s
cutoff frequency. Higher values allow the envelope
generator to vary the filter cutoff frequency over a
wider range.
04: CutoffScBP (VOICE mode only)
•Cutoff Scaling Breakpoint
•Settings: C-2 … G8
Filter cutoff frequency “scaling” ( or “key scal-
ing”) produces natural timbre variations across the
VL70-m note range by allowing an increasing or
decreasing filter “depth” curve to be applied above
or below a specified “breakpoint” note. The
“CutoffScBP” parameter specifies the breakpoint
note.
05: CutoffScDpt (VOICE mode only)
•Cutoff Scaling Depth
•Settings: -64 … +63
This parameter specifies the amount of filter cutoff
frequency key scaling to be applied above or below
Filter & Envelope Generator Editing
01(01): CutoffFreq
•Cutoff Frequency
•Settings: -64 … +63
Sets the cutoff frequency of the VL70-m filter.
02(02): Resonance
•Resonance
•Settings: -64 … +63
This parameter produces a resonant peak at the
filter’s cutoff frequency, thereby emphasizing
frequency components at that frequency. When
“Resoance” is set to its minimum value, the filter
response rolls off sharply at the cutoff point. As the
resonance value is increased, however, a peak of
correspondingly increasing amplitude is produced
at the cutoff frequency.

the breakpoint note specified by the “CutoffScBP”
parameter, above. A setting of “+00” produces no
key scaling. Positive values apply scaling to notes
below the breakpoint (i.e. on a keyboard, notes to
the left of the breakpoint), producing a gradual
lowering of the cutoff frequency down the scale.
Negative values apply scaling to notes above the
breakpoint (i.e. on a keyboard, notes to the right of
the breakpoint), producing a gradual lowering of
the cutoff frequency up the scale. Higher positive
or negative values produce a greater variation in
the filter cutoff frequency.
06(04): Bass
•Bass Tone Control
•Settings:  -64 … +63
Boosts or cuts the low frequencies. Positive values
boost the lows while negative values cut the lows.
A setting of “+00” produces no boost or cut.
07(05): Treble
•Treble Tone Control
•Settings: -64 … +63
Boosts or cuts the high frequencies. Positive values
boost the highs while negative values cut the highs.
A setting of “+00” produces no boost or cut.

08(06): Attack Time
•Amplitude & Filter Envelope Attack Time
•Settings: -64 … +63
Sets the attack time of the amplitude & filter
envelope generator. “Attack time” refers to the
length of time it takes for the envelope to reach
maximum level from the instant a note is played.
Positive values produce a slower attack while
negative values produce a faster attack.
09(07): Decay Time
•Amplitude & Filter Envelope Decay Time
•Settings: -64 … +63
Sets the decay time of the amplitude & filter
envelope generator. “Decay time” refers to the
length of time it takes for the envelope to fall to
the sustain level after the maximum attack level
has been reached. Positive values produce a slower
decay while negative values produce a faster decay. 
						

							73
10(08): ReleaseTime
•Amplitude & Filter Envelope Release Time
•Settings: -64 … +63
Sets the release time of the amplitude & filter
envelope generator. “Release time” refers to the
length of time it takes for the envelope to fall to
“zero” level after the note has been released.
Positive values produce a slower release while
negative values produce a faster release.
11: AmpLvlScBP (VOICE mode only)
•Amplitude Level Scaling Breakpoint
•Settings: C-2 … G8
Amplitude level “scaling” ( or “key scaling”)
produces natural level variations across the VL70-
m note range by allowing an increasing or decreas-
ing amplitude “depth” curve to be applied above or
below a specified “breakpoint” note. The
“AmpLvlScBP” parameter specifies the breakpoint
note.
12: AmpLvlScDpt (VOICE mode only)
•Amplitude Level Scaling Depth
•Settings: -64 … +63
This parameter specifies the amount of amplitude
level key scaling to be applied above or below the
breakpoint note specified by the “AmpLvlScBP”
parameter, above. A setting of “+00” produces no
key scaling. Positive values apply scaling to notes
below the breakpoint (i.e. on a keyboard, notes to
the left of the breakpoint), producing a gradual
Filter & Envelope Generator Editing
lowering of amplitude level down the scale.
Negative values apply scaling to notes above the
breakpoint (i.e. on a keyboard, notes to the right of
the breakpoint), producing a gradual lowering of
amplitude level up the scale. Higher positive or
negative values produce a greater variation in the
amplitude level.

13(09): PEGInitLvl
•Pitch & Embouchure Envelope Initial Level
•Settings: -64 … +63
Sets the initial level of the pitch & embouchure
envelope generator. A setting of “+00” starts the
pitch envelope at normal pitch. Positive values
raise the initial pitch while negative values lower
the initial pitch in relation to normal pitch. 
						

							74
14(10): PEGAtakTime
•Pitch & Embouchure Envelope Attack Time
•Settings: -64 … +63
Sets the attack time of the pitch & embouchure
envelope generator. In this case “attack time”
refers to the length of time it takes for the pitch
envelope to reach normal pitch (“+00” level) from
the instant a note is played. Positive values pro-
duce a slower attack while negative values produce
a faster attack.
15(11): PEGReleLvl
•Pitch & Embouchure Envelope Release Level
•Settings -64 … +63
Sets the final pitch to be reached after a note is
released. A setting of “+00” produces normal pitch.
Positive values raise the final pitch while negative
values lower the final pitch in relation to normal
pitch.
16(12): PEGReleTime
•Pitch & Embouchure Envelope Release Time
•Settings: -64 … +63
Sets the release time of the pitch & embouchure
envelope generator. “Release time” refers to the
length of time it takes for the pitch envelope to
reach the release level specified by the
“PEGReleLvl” parameter (above) after a note is
released. Positive values produce a slower release
while negative values produce a faster release.
