042: 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
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 2,730msec. If this is
exceeded, the recorded data will start being erased from the
top.
e: Response
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 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.

043: Grain Shifter

This effect cuts extremely short samples ("grains") from the
input signal waveform and plays them repeatedly, giving a
mechanical character to the sound.
