Korg KORG Pa50 user manual Filter LFO2, Filter EG, Filter LFO1 modulation, Filter envelope

Intensity to B

Specify the depth and direction of the modulation that LFO1 will have on the cutoff frequency of filter B (see “Intensity to A”).

Change in cutoff

Low setting High setting

-99…+99 Parameter value.

Joystick –Y to A

By moving the joystick in the Y direction (toward yourself), you can control the depth at which LFO1 modulates the cut- off frequency of filter A. This parameter specifies the depth and direction of the control.

Higher settings of this parameter will produce greater increases in the effect of LFO1 on the filter when the joystick is moved toward yourself.

-99…+99 Parameter value.

Joystick –Y to B

By moving the joystick in the Y direction (toward yourself), you can control the depth at which LFO1 modulates the cut- off frequency of filter B. This parameter specifies the depth and direction of the control (see “Joystick –Y to A”).

Filter LFO1 modulation

AMS (Alternate Modulation Source)

Select a source that will control the depth and direction of cutoff frequency change for both filters A and B. See “AMS (Alternate Modulation Source) list”.

Intensity to A

Specifies the depth and direction of the effect that “AMS” will have on filter A.

For example if “AMS” is Joystick +Y, higher settings of this parameter will allow greater change to be applied to LFO1 when you push the joystick.

-99…+99 Parameter value.

Intensity to B

Specifies the depth and direction of the effect that “AMS” will have on filter B (see “Intensity to A”).

PAGE 10 - FILTER LFO2

Adjusts the depth of the cyclic modulation applied by LFO2 (set on “Page 18 - LFO2”) to the cutoff frequency of filters A and B. For more information on the parameters see “Page 9 - Filter LFO1” on page 114.

PAGE 11 - FILTER EG

Here you can make settings for the EG that will produce time-varying changes in the cutoff frequency of filters A and B for the selected oscillator. The depth of the effect that these settings will have on the filter cutoff frequency is determined by the “Velocity” and “Intensity” parameters.

Use this parameter to select an oscillator to put in edit. Alter- natively, you can select oscillators using the F1-F4 buttons.

Start/Attack/Break/Sustain/Release Level

These are the envelope segment levels. The result will depend on the filter that was selected in “Filter Type”. For example, with the Low Pass Resonance filter, positive (+) values of EG Intensity will cause the tone to be brightened by positive (+) levels, and darkened by negative (–) levels.

-99…+99 Level value.

Start Level

This parameter specifies the change in cutoff frequency at the time of note-on.

Attack Level

This parameter specifies the change in cutoff frequency after the attack time has elapsed.

Break Point Level

This parameter specifies the change in cutoff frequency after the decay time has elapsed.

Sustain Level

This parameter specifies the change in cutoff frequency that will be maintained from after the slope time has elapsed until note-off occurs.

Release Level

This parameter specifies the change in cutoff frequency that will occur when the release time has elapsed.

Attack/Decay/Slope/Release Time

These parameters specify the time over which the filter change will occur.

0…99	Time value.
Attack Time

This parameter specifies the time over which the level will change from note-on until the attack level is reached.
