ting of 0, the pitch EG times will be just as specified by the
“Attack/Decay/Release Time” settings.
The alternate modulation value at the moment that the EG
reaches each point will determine the actual value of the EG
time that comes next.
For example, the decay time will be determined by the alter-
nate modulation value at the moment that the attack level is
reached.
When this parameter is set to values of 16, 33, 49, 66, 82, or
99, the specified EG times will speed up as much as 2, 4, 8, 16,
32, or 64 times respectively (or slowed down to 1/2, 1/4, 1/8,
1/16, 1/32, or 1/64 of the original time).
For example if “AMS” is set to Velocity, increasing the abso-
lute value of “Intensity” will allow strongly-played notes to
increase the changes in pitch EG “Time” values. The direc-
tion of the change is specified by “Attack Time Swing” and
“Decay Time Swing”. As you play more softly, the pitch EG
times will more closely approach the actual settings of the
pitch EG.
-99…+99 Parameter value.
Attack Time Swing
This parameter specifies the direction in which “AMS” will
affect the “Attack Time” parameter. With positive (+) values
of “Intensity”, a setting of + will cause the time to be length-
ened, and a setting of – will cause the time to be shortened.
With a setting of 0 there will be no change.
Decay Time Swing
Specify the direction in which “AMS” will affect the “Decay
Time”. With positive (+) values of “Intensity”, a setting of +
will cause the time to be lengthened, and a setting of – will
cause the time to be shortened. With a setting of 0 there will
be no change.

Here you can make settings for the filters that will be used by
the oscillators. You can select either a 24 dB/octave low pass
filter with resonance, or a series connection of a 12 dB/octave
low pass filter and a 12 dB/octave high pass filter.
Selected
Use this parameter to select an oscillator to put in edit. Alter-
natively, you can select oscillators using the F1-F4 buttons.
Filter Type
This parameter selects the type of filter (Low Pass Resonant,
Low Pass & High Pass) for the selected oscillator. When the
Low Pass & High Pass filter type is selected, the filter B will be
activated.
Trim
Use this parameter to adjust the level at which the audio sig-
nal output from the selected oscillator is input to filter A.
Note: If this value is raised, the sound may distort if Resonance
is set to a high value or when you play a chord.
00…99 Trim level.
Frequency A (Cutoff Frequency A)
This parameter specifies the cutoff frequency of filter A.
00…99 Cutoff frequency value.
Resonance A
The resonance emphasizes the overtone components that lie
in the region of the cutoff frequency specified by “Frequency”,
producing a more distinctive sound. Increasing this value will
produce a stronger effect.
00…99 Resonance value.

This is a filter that cuts the high-
frequency region above the cutoff
frequency.
This is the most common type of filter,
and is used to cut part of the overtone
components, making an originally bright
timbre sound more mellow (darker).
When the “Filter Type” is Low Pass
Resonance, the cutoff will have a
steeper slope.
