Korg Electric Keyboard manual Scratch, 181

31: Scratch

This effect is applied by recording the input signal and mov- ing the modulation source. It simulates the sound of scratches you can make using a turntable.

a: Scratch Source, b: Response(Scratch)

The Scratch Source parameter enables you to select the modula- tion source that controls simulation. The value of the modulation source corresponds to the playback position. The Response(Scratch) parameter enables you to set the speed of the response to the modulation source.

c: Envelope, c:Src, d: Threshold

When “Envelope” is set to Dmod, the input signal will be recorded only when the modulation source value is 64 or higher. When “Envelope” is set to Input, the input signal will be recorded only when its level is over the Threshold value.

The maximum recording time is 1365msec. If this is exceeded, the recorded data will start being erased from the top.

e: Response(Env)

This parameter enables you to set the speed of the response to the end of recording. Set a smaller value when you are recording a phrase or rhythm pattern, and set a higher value if you are record- ing only one note.

f: Direct Mix

With Always On, a dry sound is usually output. With Always Off, dry sounds are not output. With Cross Fade, a dry sound is usually output, and it is muted only when scratching.

Set W/D to Wet to use this parameter effectively.
