Chapter 4. Changing the settings of a sample
4
* It is not possible to specify the start/end points in a way that
would leave less than 70 ms between the beginning and end of
the sound.
* If you set the start point at the beginning of the waveform, and
set the end point at the end of the waveform, the highlighted
region will return to normal, and the start/end points will be
cancelled.
6. Press the pad to listen to the sample play back, and
check the start/end point settings.
By holding down [PAD] and pressing [F1] (START) or
[F2] (END), you can listen to the sound before or after
the start/end points.
● If you want to make fine adjustments to the start/end
points, press [ZOOM IN] to magnify the waveform
display, use the VALUE dial to move the wave pointer,
and press [F1] (START) or [F2] (END).
Press [ZOOM OUT] to shrink the waveform display and
return to the previous display.
● By holding down [L/R] and pressing [ZOOM IN]
[ZOOM OUT], you can zoom-in or zoom-out on the
vertical axis (amplitude axis) of the waveform.
● When you press [F3] (TRUNC), the screen will ask you
whether it is ok to truncate (delete) the portions before
and after the start/end points. If you want to truncate
the sample, press [F1] (YES). To cancel, press [F2] (NO).
* By executing Truncate, you can conserve sample memory and
increase the remaining time available for sampling.
* Once Truncate has been executed, it will not be possible to
return to the original start/end point locations.
7. Press [SONG] or [PTN], or press [EXIT] twice to return
to the Play screen.
Never turn off the power while the display indicates
“Keep Power On!”
Adjusting the volume of a
specified region of the sample
The volume of a specified region in a sample can be adjusted.
For example, if a sample contains noise, you can lower the
volume of the region containing the noise, to make it less
obtrusive.
* The tonal quality may change if you perform this operation
repeatedly.
* While you are adjusting the volume of a specified region in the
sample, the Play BPM setting will be ignored, and the sample
will play at its original BPM (tempo).
1. Press the pad of the sample whose volume you want to
adjust for a specified region.
2. Press [WAVE EDIT].
3. Press [F2] (AMP).
The sample waveform will be displayed.
fig.04-03
The pad number will be shown at the left side of the top
line of the display.
(Example) PAD 6-1: Pad [1] of pad bank 6
The number of samples of the wave pointer position will
be shown in the right side of the top line of the display.
* Even if the sample has been set to reverse playback, the
waveform will be displayed in the normal direction.
4. Use CURSOR [ ← ][ → ] to move the entire screen left or
right, use the VALUE dial to move the wave pointer to
the beginning of the region for which you want to
change the volume, and then press [F1] (START).
* When wave pointer locates on except the region between the
specified start and end points, the display will indicate
[*********], and it is not possible to set the beginning of the
region for which you want to change the volume.
