Adjusting The Modulation; About Alternate Modulation; About Dynamic Modulation - Korg Trinity series Basic Manual

Even if you change the multisample of a program, the parameter settings of that program will
remain at the values appropriate for the previous multisample. (For example on a piano-type pro-
gram, the Amplifier EG will be set to create a piano-type envelope, producing a rapid attack and a
gradual decay.) You can adjust the filter or amplifier parameter values as needed.

Adjusting the modulation

Effects such as vibrato and wah-wah can be produced by modulating the pitch or filter cutoff fre-
quency. Vibrato is produced by using the Oscillator LFO to modulate the pitch, and wah-wah is
produced by modulating the cutoff frequency. These effects are frequently used as you play to add
life to the sound.
On the TRINITY series, you can make very detailed settings for these types of modulation. For
example when applying vibrato, you can make settings (to the Offset parameter) so that the
vibrato will modulate the pitch only in the upward direction, in the way that vibrato occurs on a
guitar. For details refer to page 16 of the Parameter Guide, "2–2a: Waveform/Freq/Offset."
In addition to these types of modulation, the TRINITY series also provides Alternate Modulation
that allows you to specify the source, and Dynamic Modulation that allows you to control effects.

About alternate modulation

Alternate Modulation is a type of modulation that allows you to control the sound.
The AMS (Alternate Modulation Source) can be selected from the controllers that you physically
operate (such as the joystick or the ribbon controller), or types of MIDI message that are received,
or internal control sources such as the Oscillator EG or Filter LFO.
Since the TRINITY series allows you to make settings so that the modulator can be modulated,
this type of control is called "alternate modulation."
The Intensity setting determines the degree (the depth or speed) to which AMS will control alter-
nate modulation.
Control combinations that are frequently used on synthesizers (such as using the joystick or rib-
bon controller to change the pitch) are provided as special parameters separately from alternate
modulation (Ribbon (X), JS(+X), and JS(–X) of Program Edit mode P2, first tab page (OSC1 P.Mod),
third tab page (OSC2 P.Mod), etc.).
The TRINITY series provides 14 choices for alternate modulation. In single mode you can use 14
types of alternate modulation to control 14 parameters. In double mode you can use 14 types of
alternate modulation to control 27 parameters (the Oscillator EG is common to both oscillators 1
and 2).
26 different AMS selections are available. (However, not all sources can be selected for some types
of modulation.)
Refer to "8. Appendix" on page 157 of the Parameter Guide for more information about 14 Alter-
nate Modulation and 26 AMS.
< Tips for using alternate modulation >
When making settings for alternate modulation, it is important to first decide what results you
want, then what type of modulation is necessary, and finally the location of the parameter (in
the oscillator, filter, or amplifier) that must be controlled. Then select a source, and (specify the
modulation if necessary) set the Intensity.
Here's an example. If you are using a guitar-type sound and want it to sound like it's on the
edge of feedback when you move the joystick away from you, make settings so that the joy-
stick controls filter modulation.

About dynamic modulation

The balance of the "dry" sound (un-processed by the effect) and the "wet" sound (processed by
the effect) is referred to as the "effect balance."
On the TRINITY series certain effect parameters such as the effect balance and the speed of mod-
ulation etc. can be controlled while you play, providing a great deal of expressive possibilities dur-
ing a performance. The ability to control effect parameters in this way is referred to as "dynamic
modulation."
The dynamic modulation source (Src) is the source that will control dynamic modulation of the
effect. The dynamic modulation source can be selected from the controllers that you physically
