Korg Speaker System P4: Edit-AmpAmplifier settings, Filter EG, Filter 1 LFO Mod. tab, Amp Level

•“Intensity to A” and “Intensity to B” adjust the effect that keyboard tracking will have on filters A and B (☞p.13 in the Parameter Guide).

Filter EG

Adjust the effect produced by the filter EG, whose set- tings are made in the Filter 1 EG tab.

•“Velocity to A” and “Velocity to B” adjust the effect that velocity will have on the filter EG depth.

•“Intensity to A” and “Intensity to B” adjust the depth of the filter EG.

•“AMS Int to A” and “AMS Int to B” adjust the effect that AMS will have on the filter EG depth. These three settings will determine the depth of the tonal change produced by the filter EG.

Filter A/B Modulation

Set this when you wish to produce tonal change by using controllers etc. to vary the cutoff frequency.

Filter 1 LFO Mod. tab

Make settings that allow the LFO to produce cyclic changes in tone (a “wah” effect).

“LFO Intensity to A” and “LFO Intensity to B” will cause the tone to be modulated.

“JS–Y Intensity to A” and “JS–Y Intensity to B” speci- fies the depth of the wah effect that is produced when you move the joystick toward yourself.

“AMS Intensity to A” and “AMS Intensity to B” speci- fies the depth of the wah effect that is produced when you operate an “AMS” (alternate modulation source). For example if you set “AMS” to After Touch, a wah effect will be produced when you apply pressure to the keyboard.

Filter 1 EG tab

Make settings for the filter EG, which controls time- variant changes in tone. Make settings for the EG here, and set the depth of its effect in the Filter 1 Mod. tab “Filter EG” parameter (☞p.15 in the Parameter Guide).

Filter EG and Amplifier EG

When the Filter EG changes the cutoff frequency, the tone will change. However depending on the volume changes produced by the Amplifier EG, this can be heard in different ways. For example by changing the speed at which the tone and volume begin (attack) or decay, you can significantly vary the character of the tonal change. It is a good idea to adjust the changes of both the Filter EG (tone) and the Amplifier EG (vol- ume) as you proceed with editing. (☞“Amp 1 EG” tab.)

P4: Edit-Amp Amplifier settings

These settings affect the volume. Here you can adjust the way in which the Amp EG and LFO produce time- varying and cyclic changes in volume, and how the controllers etc. will affect the volume.

Amp1 applies to OSC1, and Amp2 applies to OSC2. If the “OSC Mode” is Single or Drums, only Amp1 will be available.

For example, the volume of a piano note begins at a high volume the instant you play the note, and then decreases gradually. The volume of an organ note remains constant as long as you continue pressing the key. The volume of a note on a violin or wind instru- ment can be varied during the note by the musician (i.e., by regulating the amount of pressure on the bow or the force of the breath).

Amp1 Lvl/Pan tab

Amp Level

Adjust the volume of the sound that has passed through the oscillator, filter, and amp.

Pan

Adjust the pan (stereo position) of the sound that has passed through the oscillator, filter, and amp. Nor- mally this will be set to C064. If “OSC Mode” is Dou- ble and you wish to produce a sense of stereo, you can use this setting to place oscillators 1 and 2 at the left and right. With a setting of Random, the sound will be placed at a random location each time you play a note, producing an interesting effect.

AMS Intensity

“AMS Intensity” specifies the depth of the panning effect that will occur when “AMS” is operated.

When “AMS” is set to Note Number, the pan will change according to the location you play on the key- board. With a setting of LFO1 or 2, the pan will sweep from side to side (auto pan). Other settings allow you to move the oscillator pan by operating a controller.
