Alternate Modulation Settings; The Effect Of Alternate Modulation On Various Parameters, And Example Applications - Korg Triton-Rack Parameter Manual

Alternate Modulation settings

When you receive or 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 also be controlled by the
REALTIME CONTROLS knobs of the TRITON-Rack or
by velocity, joystick, switches, or pedals of a connected
TRITON or other MIDI instrument.
• Panning can be controlled in realtime from a controller,
EG, or LFO etc.
• The filter EG can also be used to control pitch or volume
at the same time as it controls the filter.
• 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, pattern/RPPR, or an external
sequencer.
Notes for the table
*1 If Note No. is selected as an "AMS," the base value will
be C4.
*2 EXT(+) : Velocity, Poly After, After Touch, JS+Y:CC#01,

Pedal:CC#04, Slider:CC#18, KnobMod1[+],

Damper:#64, Porta.SW:#65, Sostenuto:#66, Soft:CC#67,

*3 EXT(+–): KnobMod1:#17, KnobMod2:#19,
KnobMod3:#20, KnobMod4:#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 "AMS 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 fre-
quency 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 and "AMS Intensity." However if you use the
"MIDI/Tempo Sync." function (PROG 5.3–1c), the LFO
frequency can be synchronized to the tempo and note
value.

The effect of alternate modulation on
various parameters, and example
applications
Pitch (PROG 3.1–1a)
Pitch can be controlled by the filter/amp EG, controllers, or
tempo etc.
• If you select Filter EG or Amp EG as the "AMS (Pitch
AMS)" and set "Intensity (AMS Intensity)" to +12.00,
the pitch will change up to ±1 octave in synchronization
with the EG.
• If you select Tempo as the "AMS (Pitch AMS)" and set
"Intensity (AMS 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 (PROG 3.1–1b)
Pitch EG intensity can be controlled by keyboard tracking,
controllers, or tempo.
• If you select JS+Y#01 as the "AMS (Pitch EG AMS)" and
set "Intensity (AMS Intensity)" to +12.00, moving the
joystick on the connected MIDI instrument, such as the
TRITON, in the +Y direction will gradually increase the
effect of the Pitch EG to a maximum of ±1 octave. If
"Intensity (AMS Intensity)" has a negative value, the
effect of the Pitch EG will be inverted.
Pitch LFO1/2 Intensity (PROG 3.1–2a, 3.1–3)
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 (LFO1/2 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 (AMS
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(AMS
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" button when desired
to turn on the vibrato effect.
Filter (Cutoff) Frequency (PROG 4.1–3a)
The cutoff frequency of filter A/B can be controlled by the
pitch/amp EG, controllers, or tempo. For each filter A and B
you can specify "AMS1 (Filter A/B AMS1)," Intensity (A/B
AMS1 Intensity"), "AMS2 (Filter A/B AMS2)," "Intensity
(A/B AMS2 Intensity)."
