If you select Result, the time-stretched sample will be
selected.
To select an index, hold down the [ENTER] key and
play a note on the keyboard of a connected MIDI instru-
ment. The index that includes the note you played will
be selected.
Sample waveform display: This shows the waveform of
the selected sample. As in 3-1: Loop Edit, Edit2 page, "S
(Start), "LpS (Loop Start)," and "E (End)" addresses are
shown by a solid line.
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)
S (Start):
E (End):
Specifies the start address and end address of the sample
for the currently selected index.
When you execute Time Stretch, the addresses will be
specified automatically, but the playback may be slightly
skewed due to inaccuracies in the end address, etc. If this
occurs, you can correct the addresses manually.
When you change the start address, the loop start
address will also be changed simultaneously. If you
wish to independently adjust the start address and loop
start address, save the data in step 0 , and then make
settings in the 3.1: Loop Edit Edit2 page.
To audition the sound in the specified range, play the
keyboard of a connected MIDI instrument or press the
[AUDITION] key. When you press the [AUDITION]
key, the sample in the range specified by "S (Start)" and
"E (End)" will sound at the original key.
Zero (Use Zero): ( 2.1–2b)
L/R: ( 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 you press the [F5] ("Strch") key, the Time Stretch dialog
box will appear, and you can re-do the time stretch once
again. Execute Time Stretch as described in step 6 .
0 Save the sample that you created. Press the [F6] ("Save")
key, and the Save dialog box will appear.
In "Save to No.," specify the save destination sample
number. By default, an unused sample number will be
selected. If "Overwrite" is checked, this cannot be
selected.
If you wish to delete the original sample data and over-
write it with the edited sample data, check "Overwrite".
Normally, you will leave "Save to No." at its default set-
ting, and execute without checking "Overwrite." ( p.85
"*": About "Overwrite")
In the case of a stereo sample, the dialog box will
indicate "To Sample No. (L)" and "To Sample No. (R)."
Specify the save destination sample for the L channel and
R channel.
To execute the Save operation, press the [F8] ("OK") key.
To cancel without saving press the [F7] ("Cancel") key.
A By repeating steps 9 – 0 you can create more samples as
desired.
98
B Press the [F7] ("Exit") key to exit the Time Stretch opera-
tion.
The index will specify the last-saved sample number.
If you wish to use the saved sample in Program mode
or Multi mode, you must either execute "Conv. To
Prog" ( 1.1–3g), or use Program mode "Multisample
Select" ( PROG 2.1–2b, 2.1–3) to select the multisam-
ple and create a program.
Be aware that the created sample will be lost if you exit
Time Stretch without saving the sample in the Save dia-
log box.
Time Stretch requires vacant samples, multisamples,
and relative parameters in order to execute. Before you
execute, make sure that there is sufficient free space. If
there is not, an error will occur.
To use Time Stretch (Slice)
1 Use "SMPL" (3.1–1b) to select the sample that you wish
to time stretch as Slice.
2 From the Edit2 page "UTILITY," choose "Time Stretch"
to open the following dialog box.
3 Select "Slice" as the time stretch method.
Press the [F8] ("OK") key to execute Time Stretch, or
press the [F7] ("Cancel") key to cancel without executing.
If the L and R of a stereo sample are different in
length, blank data will automatically be added to the end
of the shorter sample so that it matches the longer side.
4 A dialog box for executing Time Stretch will appear.
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.
