Korg KORG Pa50 Attack Time Swing Wave, Release Time, AMS2 Alternate Modulation Source, Frequency

The LFO will start each time you play a note, and an independent LFO will operate for each note.

The LFO effect that was started by the first- played note will continue to be applied to each newly-played note. (In this case, Delay and Fade will be applied only to the LFO when it is first started).

(–)values will cause EG times to shorten as you play more strongly. With a setting of 0, the EG times will be as specified by the “Amp envelope” parameters (see page 14-118).

Attack Time Swing

Wave

This parameter selects the LFO waveform. The numbers that appear at the right of some of the LFO waveforms indicate the phase at which the waveform will begin.

This parameter specifies the direction of the effect that “AMS1” will have on “Attack Time”. With positive (+) values of “Intensity”, setting this parameter to + will allow AMS1 to lengthen the time, and setting it to – will allow AMS1 to shorten the time. With a setting of 0 there will be no effect.

Decay Time Swing

This parameter specifies the direction of the effect that “AMS1” will have on “Decay Time”. With positive (+) values of “Intensity”, setting this parameter to + will allow AMS1 to lengthen the time, and setting it to – will allow AMS1 to shorten the time. With a setting of 0 there will be no effect.

Slope Time Swing

This parameter specifies the direction of the effect that “AMS1” will have on “Slope Time”. With positive (+) values of “Intensity”, setting this parameter to + will allow AMS1 to lengthen the time, and setting it to – will allow AMS1 to

Random1 (S/H):

Conventional sample & hold (S/H) in which the level changes randomly at fixed intervals of time

Random2 (S/H):

Both the levels and the time intervals will change randomly.

Random3 (S/H):

The maximum level and minimum level will alternate at random intervals of time (i.e., a square wave with random period).

Release Time

This parameter specifies the direction of the effect that “AMS1” will have on “Release Time”. With positive (+) val- ues of “Intensity”, setting this parameter to + will allow AMS1 to lengthen the time, and setting it to – will allow AMS1 to shorten the time. With a setting of 0 there will be no effect.

AMS2 (Alternate Modulation Source 2)

This is another alternate modulation source for the Amp EG. See above “AMS1” parameters.

Frequency

Set the LFO frequency. A setting of 99 is the fastest.

00…99 Frequency rate.

Key Sync

This parameter specifies if the LFO is synchronized to key strokes.

PAGE 17 - LFO1

In this and the next page you can make settings for the LFO that can be used to cyclically modulate the Pitch, Filter, and Amp of each oscillator. There are two LFO units for each oscillator. By setting the LFO1 or LFO2 Intensity to a negative

(–)value for Pitch, Filter, or Amp, you can invert the LFO waveform.

Offset

This parameter specifies the central value of the LFO wave- form. For example, with a setting of 0 as shown in the follow- ing diagram, the vibrato that is applied will be centered on the note-on pitch. With a setting of +99, the vibrato will only raise the pitch above the note-on pitch, in the way in which vibrato is applied on a guitar.

When “Wave” is set to Guitar, the modulation will occur only in the positive (+) direction even if you set “Offset” to 0. Here are offset settings and pitch change produced by vibrato

Pitch	offset = –99	offset = 0	offset = +99

-99…+99 Offset value.

Delay

This parameter specifies the time from note-on until the LFO effect begins to apply. When “Key Sync” is Off, the delay will apply only when the LFO is first started.

0…99 Delay time.

Fade In

This parameter specifies the time from when the LFO begins to apply until it reaches the maximum amplitude. When “Key Sync.” is Off, the fade will apply only when the LFO is first started.
