When the Intensity is set to a negative (–) value, the effect of
the EG is reversed; positive EG values mean lower pitches,
and negative EG values mean higher pitches.
AMS (Pitch EG) [List of AMS Sources]
This selects any AMS modulation source to scale the amount
of the Pitch EG applied to the pitch.
For a list of AMS sources, see “Alternate Modulation Source
(AMS) List” on page 901.
Intensity [–12.00…+12.00]
This controls the depth and direction of the pitch EG AMS
modulation. The AMS modulation and the initial Intensity
are added together to determine the Pitch EG’s final effect.
With positive (+) values , greater modulation will increase
the effect of the Pitch EG, as shown in example B below.
Pitch EG AMS
With negative (–) values , greater modulation will introduce
the opposite effect of the Pitch EG–like inverting the polarity
of the envelope. You can use this in several different ways:
• You can set an initial positive amount with the Intensity
parameter, and then reduce this amount with AMS. In
this case, the final effect of the EG is simply diminished,
and not actually inverted, as shown in example
C .
• You can also set the AMS Intensity amount to be greater
than the initial Intensity. In this case, the EG will have a
positive effect with low modulation amounts, and an
inverted effect at higher modulation amounts–as shown
in example
D .
2–2c: LFO1/2
LFO1 and LFO2 can both modulate the pitch. You can
control the strength of each LFO’s modulation in three
different ways:
• Set an initial amount of LFO modulation, using the LFO
1/2 Intensity parameters.
• Use JS+Y to scale the amount of the LFO.
• Use any AMS source to scale the amount the LFO.
You can use each of these methods for each of the two LFOs.
The results are added together to produce the total LFO
effect.
LFO1
LFO1 Intensity [–12.00…+12.00]
This controls the initial effect of the LFO on the pitch, in
semitones, before any JS+Y or AMS modulation.
Negative (–) settings will invert the phase of the LFO.
JS+Y Intensity (LFO1 JS+Y Int.) [–12.00…+12.00]
Moving the joystick “up” from the center detent position,
away from yourself, produces the JS+Y controller. You can
use this to scale the amount of the LFO applied to the pitch.
This parameter sets the maximum amount of LFO
modulation added by JS+Y, in semitones.
As this value is increased , moving the joystick in the +Y
direction will cause the OSC1 LFO1 to produce deeper pitch
modulation.
Negative (–) settings will invert the phase of the LFO. You
can also use this to reduce the initial amount of the LFO, as
set by
LFO1 Intensity , above. For example:
1. Set LFO1 Intensity to +7.00.
The LFO will now have a fairly strong effect on the pitch,
bending it by a perfect 5th.
2. Set JS+Y Intensity to –7.00.
Now, if you move the joystick up, the effect of the LFO will
fade away. When the joystick is all the way at the top of its
range, the LFO will be completely canceled out.
AMS (LFO1) [List of AMS Sources]
This selects any AMS modulation source to scale the amount
of the LFO applied to pitch.
For a list of AMS sources, see “Alternate Modulation Source
(AMS) List” on page 901.
Intensity [–12.00…+12.00]
This controls the depth and direction of the LFO AMS
modulation for pitch.
For example, if AMS is set to After Touch , positive settings
mean that aftertouch will increase the amount of pitch
modulation from LFO1.
LFO2
The parameters for LFO2 are identical to those for LFO1.
For more information, see the descriptions under LFO1,
above.
2–2d: Portamento
Portamento lets the pitch glide smoothly between notes,
instead of changing abruptly.
Enable [Off, On]
On (checked): Turns on Portamento, so that pitch glides
smoothly between notes.
Off (unchecked): Turns off Portamento. This is the default
state.
Fingered [Off, On]
This parameter allows you to control Portamento through
your playing style. When it’s enabled, playing legato will
turn on Portamento, and playing detached will turn it off
again.
This option is only available when Portamento Enable is
turned on.
On (checked): Turns on Fingered Portamento.
Off (unchecked): Turns off Fingered Portamento.
