As an alternative to the “Time Slice” command, “Time
Stretch” (☞2–1C) is another way to change the tempo of
a rhythm loop or similar sample. You may wish to use
this if you don’t need to divide the sample and create
song performance data for the divided samples.
1 Select the sample in the “Sample Select” (2–1b) for which
you wish to execute Time Slice.
2 Select the “Time Slice” to access the dialog box.
3 Specify the number of quarter-note beats and tempo of
the currently selected sample. If you know the BPM of
the original waveform, set “Source BPM.” If you do not
know the BPM, specify “Beat” and the BPM will be calcu-
lated automatically. The setting you make here will be
used as the reference value when detecting the attack,
when performing Time Stretch in step
9b, and when
saving the sequence data in step
0.
Beat: Specifies the number of quarter-note beats. When
you specify “Beat,” the “Source BPM” will indicate the
playback BPM at the original key. This BPM value will
automatically be calculated from the start address to the
end address (if loop is off) or from the loop start address
to the end address (if loop is on) of the selected sample. If
you know the BPM and it is different than the displayed
value, change “Source BPM” to the correct value.
For example in the case of a 120 BPM sample of one mea-
sure of 4/4 time, set “Beat” to 4. The “Source BPM” will
be calculated automatically. If the “Source BPM” is not
set to 120, due to inaccuracies in the start address (or loop
start address) and end address, change the “Source
BPM” to 120.
Source BPM: Specifies the tempo at the original key of
the source waveform.
4 To execute Time Slice, press the OK button. To cancel
without executing, press the Cancel button. When you
press the OK button, the attacks will be detected, the
sample will automatically be sliced, and a dialog box will
appear.
In the case of a stereo sample in which L and R
have different lengths, silent data will automatically be
added to the end of the shorter sample so that the two
samples will be the same length.
If you want to re-set “Beat” and “Source BPM” after
pressing the OK button, you can do so in step
9a).
5 Listen to the samples that were divided by detecting
their attacks. The sample before slicing is assigned to the
C2 note of the keyboard, and the sliced samples are
assigned to notes D2 and above. When you change the
“Index,” the corresponding display will be highlighted,
allowing you to view the sliced waveforms.
You can also select an index by holding down the
[Enter] key and pressing a note on the keyboard. The
index that is assigned to the note you pressed will be
selected.
To hear the sliced sounds, you can either press the cor-
responding note on the keyboard, or change the index
to select the desired sample and then press the SAM-
PLING [START/STOP] key. When you press the SAM-
PLING [START/STOP] key, the sample in the range
between the specified “Start” and “End” will be played
at the original key.
Keyboard & Index: This shows the multisample that is
being used temporarily in this dialog box.
When you play the keyboard, this multisample will
sound. It will behave in the same way as in normal pages
(such as the Recording page). (☞0–1a)
In the case of a stereo sample, a stereo multisam-
ple will be temporarily used. The sample at each index
will sound in stereo.
Index [Source, xxx(001...090)/yyy(001...090)]:
Selects the sample index.
If this is set to Source, the original waveform before time
slicing will be selected.
By selecting xxx/yyy you can specify individual samples
that were sliced. xxx indicates the selected sample, and
yyy indicates the total number of samples that were
sliced. A maximum of 90 samples can be assigned to the
keyboard. If more than 90 samples were sliced, this will
display 90.

each sample to optimize the “spacing” to match the tempo. ☞9
