Korg Electric Keyboard manual Alternate Modulation settings, 214

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.

•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 or sequencer.

Notes for the table on the lower right

*1 If Note No. is selected as an “AMS,” the base value will be C4.

*2 EXT(+) : Velocity, Poly After, AfterT, JS+Y #01, JS–Y #02, JS+Y&AT/2, JS –Y&AT/2, Pedal #04, Slider #18, KnobM1[+], KnobM2[+], KnobM3[+], KnobM4[+], Damper #64, Porta.SW #65, Soste. #66, Soft #67, SW 1 #80, SW 2 #81, MIDI CC#83

*3 EXT(+–): KnobM1 #17, KnobM2 #19, KnobM3 #20, KnobM4 #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 “Filter 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 and “AMS Intensity.” However if you use the “Sync. (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, 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, 3.1–4)

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 (LFO 1/2 AMS),” you can press the “SW1” or “SW2” button when desired to turn on the vibrato effect.

Filter (Cutoff) Frequency (PROG 4.1–3a, 4.1–3b)

The cutoff frequency of filter A/B can be controlled by the pitch/amp EG, controllers, or tempo. Set “AMS 1/2 (Filter A/B AMS1/2)” and “AMS 1/2 Intensity” for Filter A or B.

•If you set “AMS1 (Filter A AMS1)” to JS X, and set “Intensity (A AMS1 Intensity)” to a positive (+) value, moving the joystick 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 result.
