5 Specify the number of quarter note beats and tempo of
the currently selected sample. If you already know the
BPM value, set "Source BPM." If you do not know the
BPM, setting "Beat" will cause the BPM to be calculated
automatically. The settings here are also used as the refer-
ence values when detecting the attacks at which the sam-
ple is divided.
Beat: Specify the number of quarter note beats. When
you change "Beat," the "Source BPM" will indicate the
BPM value for playback at the original key. This BPM
value is automatically calculated according to the length
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). If you already know the BPM value and the calcu-
lated value is incorrect, change "Source BPM" to the cor-
rect value.
For example if you have a one-measure 120 BPM sample
in 4/4 time, you would set "Beat" to 4. The "Source
BPM" will be calculated automatically. If the "Source
BPM" is not calculated as 120 due to inaccuracies in the
start address (or loop start address) or end address,
adjust "Source BPM" to the correct value of 120.
Source BPM: Specify the tempo at the original key of the
original waveform.
"Source BPM" cannot be set or displayed outside the
range of 40–480.
6 Set the proportional length of the sample that will be cre-
ated by Time Stretch.
• To specify the length as a ratio
Set "Ratio." The available range is 50.00%–200.00%. If
you specify 50.00%, the sample playack time will be
halved. (The tempo will double.) If you specify 200.00%,
the sample playback time will double. (The tempo will be
halved.)
The tempo of the sample created by execution will be cal-
culated automatically from the "Ratio" and "Source
BPM," and displayed in "New BPM."
• To match a desired BPM tempo value
Set "New BPM" to the desired BPM value of the sample
that will be created. "Ratio" will automatically be calcu-
lated from the "Source BPM" and "New BPM" values.
It is not possible to set or display "New BPM" outside
the range of 40–480. It is not possible to set or display
"Ratio" outside the range of 50.00–200.00.
7 To execute Time Stretch, press the [F8] ("OK") key. To
cancel without executing, press the [F7] ("Cancel") key.
When you press the [F8] ("OK") key, the attacks will be
detected and the sample will be divided automatically,
and time stretch will be performed.
The Time Stretch dialog box will appear.
8 Audition the results that were created by Time Stretch.
The original sample (before being time-stretched) is
assigned to the C2 note of the keyboard. The time-
stretched sample is assigned to C#2. Sliced (divided)
samples will be assigned consecutively upward, starting
from D2 on the keyboard.

Index
xxx: 001...090(zzz: D2...G9)/yyy: 001...090]:
Select s the index for the sample whose waveform you
wish to display.
If you select Source, the original waveform before time-
stretching will be selected.
If you select Result, the time-stretched sample will be
selected.
If you set this to xxx(zzz)/yyy, an individually sliced sam-
ple will be selected. xxx is the selected index, and yyy
indicates the total number of sliced samples. zzz indi-
cates the number of notes that are assigned to the
selected index. A maximum of 90 samples can be
assigned to the keyboard. If the sample was sliced into
more than 90 samples, this will be displayed as 90.
To select an index, hold down the [ENTER] key and
play a note on the keyboard. The index that includes
the note you played will be selected.
When you execute Time Stretch, the addresses will be
specified automatically. However, playback may be
slightly offset due to inaccuracies in the end address,
etc. If this occurs, set "Index" to Result, and use "S
(Start)" and "E (End)" to re-specify the addresses.
Sample waveform display: This displays the waveform
of the selected sample. If the "Index" is other than
Result, the locations at which the sample is sliced will be
indicated by a dotted line (vertical). If "Index" is set to
xxx(zzz)/yyy, the sample of the selected index will be
highlighted. If "Index" is other than xxx(zzz)/yyy, the
Start, Loop Start, and End addresses will be indicated by
solid lines (vertical).
In the case of a stereo sample, you can press the
[F3] ("L/R") key to switch the display between the L
channel and R channel of the sample data. ( ☞ 2.1–2c)
ZOOM: When you press the [F8] ("Zoom") button the
zoom buttons will appear, allowing you to zoom-in or
zoom-out vertically or horizontally on the sample wave-
form display ( ☞ 2.1–2d). Press the [F8] ("Zoom") key
once again to return to the previous display.
9 If the slice locations are not appropriate, use "Sensitivity"
to modify the sensitivity at which the attacks are
detected, thus changing the slice locations.

Refer to "Time Slice" steps 6 and 7 .
0 When you press the [F5] ("Strch") key, the Time Stretch
dialog box will appear, and you can re-do the time
stretch. Execute Time Stretch using the same procedure
as in step 4 – 7 . If the sample slice locations are not
appropriate, this will also affect the result of Time
Stretch. For details on setting the slice locations, refer to
"Time Slice," steps 6 and 7 .
A Save the sample you created. Press the [F6] ("Save") key,
and the Save dialog box will appear.
