194 Effects
Pitch/Phase Mod.
031: Scratch
This effect is applied by recording the input signal and
moving the modulation source. It simulates the sound
of scratches you can make using a turntable.

a: Scratch Source, b: Response
The Scratch Source parameter enables you to select the
modulation source that controls simulation. The value of the
modulation source corresponds to the playback position. The
Response parameter enables you to set the speed of the
response to the modulation source.

c: Envelope Select, c: Src, d: Threshold
When "Envelope Select" is set to D-mod, the input signal will
be recorded only when the modulation source value is 64 or
0...100
higher.

When "Envelope Select" 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
0...100
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
0...100

you are recording 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 Wet/Dry to Wet to use this parameter effectively.
