AMS (Pitch EG)
This selects any AMS modulation source to scale the
amount of the Pitch EG.
For a list of AMS sources, please see "AMS (Alternate Mod‐
ulation Source) List" on page 121.
AMS Intensity
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.
With negative (–) values, greater modulation will introduce
the opposite effect of the Pitch EG–like inverting the polar‐
ity 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.

Portamento lets the pitch glide smoothly between notes,
instead of changing abruptly.

LFO1
LFO1 and LFO2 can both control 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
"LFO1 Int."parameter.
• Use "JS +Y Int." to adjust the amount of LFO produced
by JS+Y operations.
• Use any AMS source to scale the amount of the LFO.
The results are added together to produce the total LFO
effect.
LFO1 Intensity
This controls the initial effect of the LFO on the pitch, in
semitones, before any JS+Y Int. or AMS modulation.
Negative (–) settings will invert the phase of the LFO.
JS+Y Intensity
Specify the depth of pitch modulation produced by OSC1
LFO1 when the joystick is moved in the +Y (away) direction
(or when CC#1 is received). (Joystick control in the +Y direc‐
tion is called "JS +Y.")
This parameter sets the maximum amount of LFO modula‐
tion 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 Int., above. For example:
1. Set "LFO1 Int." 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 Int." 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 cancelled out.
AMS (LFO1)
This selects any AMS modulation source to scale the
amount of the LFO thatʹs applied to pitch.
For a list of AMS sources, please see "AMS (Alternate Mod‐
ulation Source) List" on page 121.
AMS Intensity
This controls the depth and direction of the "AMS (LFO1)"
modulation for pitch.
With a setting of 0, modulation will not be applied. With a
setting of 12.00, the OSC1 LFO1 will apply a maximum of +/
–1 octave of pitch modulation.
For example if "AMS (LFO1)" is set to JS+Y: CC#01 and you
move the joystick in the +Y direction, pitch modulation from
OSC1 LFO1 will be applied in positive phase if this is a posi‐
tive (+) value, or applied in negative phase if this is a nega‐
tive (–) value.
"LFO1 Int.," "JS+Y Int.," and "AMS (LFO1)" settings are
summed to determine the depth and direction of pitch mod‐
ulation produced by OSC1 LFO1.
LFO2
The parameters for LFO2 are identical to those for LFO1.
For more information, please see the descriptions under
LFO1, above.
