Alternate Modulation settings
When you operate an AMS (Alternate Modulation Source),
the modulation destination will be affected as shown in the
table below.
By using alternate modulation, you can create complex sys-
tems of modulation in which EG, LFO, keyboard tracks, and
controllers work together.
• You can apply complex change to an LFO or EG, for
example by using the pitch/filter/amp EG to control the
frequency or intensity of an LFO that modulates the
pitch/filter/amp, or by using LFO2 to control the
frequency of LFO1.
• The tone, EG, and LFO etc. can be controlled not only by
velocity or joystick, but also from a switch, knob, or
pedal etc.
• Panning can be controlled in realtime from a controller,
EG, or LFO etc.
• Controllers etc. can be used to control EG levels or times.
This lets you shape the EG in realtime.
• Filter/amp keyboard tracking or note number can be
used to control the EG or LFO according to the keyboard
pitch that is played.
• Pitch, tone, EG or LFO can be controlled by the tempo of
the arpeggiator or sequencer.
Notes for the table
*1
If Note Number is selected as an AMS, the base value
will be C4.
*2 EXT(+): Velocity, Poly After, After Touch, JS+Y:CC#01,
JS(–Y):CC#02, JS+Y & AT/2, JS –Y & AT/2, Pedal:CC#04,
Slider:CC#18, KnobMod1[+], KnobMod2[+],
KnobMod3[+], KnobMod4[+], Damper:#64,
Porta.SW:#65, Sostenuto:#66, Soft:CC#67, SW1:CC#80,
SW2:CC#81, MIDI:CC#83
*3 EXT(+–): KnobMod1:#17, KnobMod1:#19,
KnobMod1:#20, KnobMod1:#21
*4 If Tempo is selected as an AMS, the base value will be
=120
. For example if the AMS for “Pitch” is set to Tempo,
and “Intensity” is set to 12.00, doubling the tempo value
( =120
→
240) will raise the pitch one octave, and halving
the tempo ( =120
→
60) will lower the pitch one octave.
*5 A dedicated parameter is also provided.
*6 This will be added to the “Filter Frequency” value. As the
“Frequency” value increases by 10, the cutoff frequency
will double (rise one octave).
*7 This will be added to the “Pan” setting.
*8 It is possible to control LFO “Frequency” by using Tempo
“AMS” and “Intensity.” However if you use the Frequency
MIDI/Tempo Sync function (Program P5: 5–1c), the LFO
frequency can be synchronized to the tempo and note
value.
The effect of alternate modulation on
various parameters, and example
applications
Pitch (Program P2: 2–1a)
Pitch can be controlled by the filter/amp EG, controllers, or
tempo etc.
• If you select Filter EG or Amp EG as the “AMS” and set
“Intensity” to +12.00, the pitch will change up to ±1
octave in synchronization with the EG.
• If you select Tempo as the “AMS” and set “Intensity” to
+12.00 , doubling the tempo (based on =120) will raise
the pitch one octave, and halving the tempo will lower
the pitch one octave.
Pitch EG Intensity (Program P2: 2–1b)
Pitch EG intensity can be controlled by keyboard tracking,
controllers, or tempo.
• If you select JS +Y:CC#01 as the “AMS” and set
“Intensity” to +12.00, moving the joystick in the +Y
direction will gradually increase the effect of the Pitch
EG to a maximum of ±1 octave. If “Intensity” has a
negative value
, the effect of the Pitch EG will be
inverted.
Pitch LFO 1/2 Intensity (Program P2: 2–1d)
Pitch modulation intensity of the LFO1/2 can be controlled
by an EG, keyboard tracking, controllers, or tempo etc.
• If you select EG as the “AMS”, the pitch change width of
LFO modulation etc. can be controlled in
synchronization with the level changes of the EG. With
positive (+)
settings of “Intensity,” the vibrato effect will
gradually deepen as the EG level rises, or gradually
lessen as the EG level decreases. With negative (–)
settings of “Intensity,” the LFO phase will be inverted.
• If you select a controller such as SW1 or 2 as the “AMS”,
you can press the [SW1] or [SW2] key when desired to
turn on the vibrato effect.
Filter (Cutoff) Frequency (Program P3: 3–2c)
The cutoff frequency of filter A/B can be controlled by the
pitch/amp EG, controllers, or tempo. Set “AMS” and
“Intensity” for Filter A or B.
• If you select JS X or Ribbon:CC#16 as the “AMS” and
set “Intensity” to a positive (+) value, moving the
joystick or ribbon controller toward the right will raise
the cutoff frequency, and moving it toward the left will
lower the cutoff frequency. Negative (–) settings will
have the opposite effect.
