KORG EA-1
Manual de Usuario

Tempo Delay settings
Set the Type Select button to Tempo Delay, and adjust the delay. Delay is an effect that plays back a time-delayed version of the original signal, and is also known as "echo." Tempo Delay is a delay that can automatically synchronize the delay time to the tempo of a pattern. If the MIDI Clock parameter is set to "Ext" (external), the delay time can also be synchronized to the clock of an external device. (Refer to p.39 "Synchronizing the EA-1 and an external MIDI device.")

� Depth (delay depth)

0...100

Adjust the depth of the delay and the amount of feedback (the number of delay repeats). Rotating the knob toward the right will increase the level of the delayed sound and the amount of feedback. Raising the Depth excessively may cause the sound to distort.

4.Pattern mode

������������������������������������������
Resonance 0...100 � Time (delay time)
This parameter adds character to the sound by boosting the region around the cutoff frequency. If you raise the resonance and turn the Cutoff knob (or adjust EG Int and Decay), you will hear the typical "meow-ing" sound typical of analog synthesizers. If the resonance is raised, the sound may be distorted depending on the cutoff frequency or on the pitch that you play.

4.Pattern mode

1/4...8

Set the delay time. Rotating the knob toward the right will lengthen the delay time. If you have selected Tempo Delay as the effect type, this parameter will let you set the tempo in terms of sixteen different multiples of the step: 1/4, 1/3, 1/2, 2/3, 3/4, 1, 1.33, 1.5, 2, 2.5, 3, 4, 5, 6, 7, or 8. Depending on the tempo setting, it may be impossible to set the delay time. In such cases, set the delay time to half the desired value.

EG Int (EG intensity)

�100...0...100

Specify the depth and direction of the effect that the EG (envelope generator) will have on the cutoff frequency. The EG will start when trigger-on occurs (the instant you play the keyboard). If this knob is in the center position, the EG will have no effect. If the gate time length of a step extends beyond the point at which the next step is sounded, the EG will not be re-triggered for the next step.

Chorus/Flanger settings
Set the Type Select button to Chorus/Flanger, and adjust the chorus/flanger. Chorus creates minute differences in the pitch to produce an ensemble effect, and Flanger adds a "swooshing" modulation to the sound.

� Depth (chorus/flanger depth)

0...100

Decay

0 msec ... 10 sec

Adjust the depth of the chorus/flanger effect. Rotating the knob toward the right will change from a chorus effect to a flanger effect. Raising the depth excessively may cause the sound to distort.

Specify the time over which the EG will decay. In conjunction with the Cutoff and EG Int parameters, this controls the way in which the sound will change over time. If EG Int is set to a negative (�) setting, Decay Time can be used in place of Attack Time.

Time (LFO rate)

0.2 Hz ... 5,000 Hz

AMP
These parameters adjust the volume level and distortion effect.

Adjust the LFO speed of the chorus/flanger. Rotating the knob toward the right will speed up the LFO.

Distortion

On, Off

Turn distortion on/off. Distortion is an effect that intentionally distorts the sound to produce a hard sound even from a mellow waveform. It is highly effective to raise the resonance and use distortion.

Level
Adjust the volume.

0...100

Effect
Here you can apply effects to the sound.

Type Select

Tempo Delay, Chorus/Flanger

The Depth and Time knobs will edit the effect that is selected by Type Select.
