Sample mode

172

G [F6] key (FIND)

Executes automatic detection of the loop points.

3. Press the [F6] key (FIND).

The sample will be searched from the beginning to ﬁnd an appropriate loop start point, and

this will be set as the loop start point. Play a pad or your MIDI keyboard to check the result.

4. Make fine adjustments to the detected loop point as necessary.

■ Applying crossfading

Crossfade looping is a function that rewrites the waveform before and after the loop

start/end points so that the loop will be connected smoothly. This is a convenient way to

minimize the noise that can occur where the loop is joined.

1. In the Trim/Loop page, enable looping and set the loop start/loop end points to

the approximate locations you want.

2. Move the cursor to the LP start or LP END ﬁeld, and press the [WINDOW] key.

The Find Loop popup window will appear.

3. Move the cursor to the

X-fade length ﬁeld

, and specify the length of the crossfade.

The setting of this ﬁeld speciﬁes the length over which the waveform will be rewritten

before and after the loop point. If this is too short or too long, the loop will not sound

natural.

4. Move the cursor to the Curve ﬁeld, and select one of the following as the

crossfade curve.

• LINEAR ......................Apply linear crossfading before and after the loop point.

• LOG .............................Apply logarithmic crossfading before and after the loop point.

• SINE ............................Apply sine curve crossfading before and after the loop point.

5. To execute crossfade looping, press the [F4] key (X-FADE).

The Keep or Retry popup window will appear.

6. Use the [F3] key (P

ORIGIN) and [F4] key (P

NEW) to compare the original

data with the results of the crossfade.

7. If you are satisfied with the edited result, assign a new name to the sample as

desired, and press either the [F2] key, [F5] key, or [F6] key to save it as a new

sample.

Hint: If you press the [F2] key (OVER WR), the new sample name will be ignored, and the data will

be overwritten onto the previous ﬁle.

This operation (crossfading) is destructive editing. Be aware that if you execute overwriting, you will

not be able to recover the original ﬁle.
