Korg TR Parameter Manual page 124

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 set.
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."
*1
(☞p.101 " : About "Overwrite"")
If you execute this command with "Overwrite"
checked, the original sample data will be deleted, and
overwritten by the edited sample data. Thus, in the
Time Stretch dialog box that appears after execution,
the edited sample data will automatically have its
attacks detected and sliced, and displayed in "Index"
Source.
In the case of a stereo sample, the display will
show "To Sample No. (L)" and "To Sample No. (R)."
Specify the L channel and R channel save destination
sample numbers respectively.
To execute the Save, press the [F8] ("OK") key. To cancel
without executing, press the [F7] ("Cancel") key.
B By repeating steps 0 – A you can create more time
stretched samples as desired.
C Press the [F7] ("Exit") key to end the Time Stretch opera-
tion.
The last-saved sample number will be set for the index.
If you wish to use the saved sample in Program mode
or Sequencer mode, you must either execute "Conv. To
Prog" (☞p.99, 1.1–3f), or use Program mode "Multi-
sample Select" ( ☞ PROG 2.1–2b, 2.1–3) to select the
multisample 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.
Before executing Time Stretch on a long sample, you
should first divide the sample into measures. In some
cases, it may not be possible to assign the sample to the
note number or edit the slice locations.
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.
If you open the time slice (Slice) dialog box on the same
sample, it will be sliced in the same way as previously.
These slice locations will also be used if you execute
"Time Slice" ( ☞ 3.1–2e), so that you can execute time
stretch without having to make the settings again.
If you wish to detect the attacks again or to re-do the
operation, change the "Sensitivity" after you open the
dialog box.
Crossfade Loop
When pitched instrumental samples such as strings or
winds are looped to sustain a note, the sound will "jump" or
"skip" repeatedly during playback if there is a significant
difference between the waveforms at the loop start and loop
end locations.
In order to solve such problems, Crossfade Loop causes the
sound to change gradually from the end to the beginning of
the loop.
Sound
Playback
(first half of loop)
In actuality, the sample data is created as follows. A specific
length (the "Crossfade Length") of the waveform immedi-
ately before the beginning of the loop is taken and mixed
with the end portion.
At this time, the waveform level of the portion immediately
before the end (the length specified by "Crossfade Length")
will gradually decrease, and the waveform level immedi-
ately before the beginning of the loop will gradually
increase as the two are mixed.

Length
1 Use "SMPL" (3.1–1b) to select the sample that you wish
to crossfade.
2 From the Edit2 page "UTILITY," choose "Crossfade
Loop" to open the following dialog box.
3 In "Crossfade Length," specify the length of the sample
that you wish to crossfade.
If you set this as %, "Crossfade Length" will be calcu-
lated automatically. Specify the proportion of the "Cross-
fade Length" relative to the length between the loop start
and loop end. If you set this to 50%, crossfade will be per-
formed on the second half of the region between loop
start and loop end.
If the length from the beginning of the sample to the
loop start is shorter than the length from the loop start
to the loop end, "Crossfade Length" can be set only up
to the length from the beginning of the sample to the
loop start. In this case, a setting of 100% will not be pos-
sible.
4 Set "Curve" to specify how the volume will change in the
crossfaded region.
Linear: The volume will change linearly.
