Using Time Slice - Korg NAUTILUS 61 AT Operation Manual

Sampling (Open Sampling System)

Using Time Slice

Time Slice is a function that detects the attack of the kick or
snare etc. in a rhythm loop sample (a sample consisting of a
looped pattern of drums etc.), and automatically divides it
into separate instrumental sounds. Each of the divided
instrumental sounds is made into a sample of its own, and
then automatically expanded into a multisample and
program. Pattern playback data for the SEQUENCER mode
using the divided samples is also created automatically.
The time-sliced sample can be used in the following ways by
the song of SEQUENCER mode.
• Multiple rhythm loop samples of differing tempo can be
matched to the same tempo without changing their pitch.
• You can change the tempo in realtime without affecting
the pitch.
As an example, we will describe how a rhythm loop sample
can be time-sliced in SAMPLING mode, and then how the
rhythm loop sample can be played in SEQUENCER mode.
You will need to provide rhythm loop samples of drums etc.
You can either record these on the NAUTILUS, or load them
in MEDIA mode. Initially, you should try this using a one-
measure pattern in 4/4 time with a fairly simple beat, and
record the pattern as a mono rhythm loop sample.
1. Use "Sample Select" to select the sample data that you
want to time-slice.
Play back the sample, and verify that the beats that you
want to loop are played cleanly.
If they are not played cleanly, make the appropriate
settings for the start address Start and end address End,
and execute the page menu command Truncate (See
"Loop settings" on page 138).
2. Go to the Loop Edit page. Select the page menu
command "Time Slice."
The Set Sample Tempo dialog box will appear.

3. Specify the number of quarter-note beats in the
sample, and its tempo.
If you know the tempo in BPM, set the Source BPM
accordingly.
If you do not know the BPM, use Beat to enter the total
number of beats, and the BPM will be calculated
automatically.
4. Press the OK button.
The sample will automatically be sliced, and a dialog box
will appear.
When you play the keyboard, C2 will play the original
sample (Source), and D2 and subsequent keys will play
the divided samples.
While listening to each divided sample, adjust Sensitivity
so that each drum strike or other rhythm instrument sound
is divided into its own sample. In some cases, it may not
be possible to slice the sample cleanly even if you adjust
Sensitivity. If the attack of the next sound is included in
the end of the preceding sample, or if one sample
contains two notes, you will need to edit the samples.
If you want to edit, hold down the ENTER button and
select the Index that is assigned to the note that you want
to edit. (This portion of the waveform display will be
highlighted.) Then you can make adjustments by
adjusting Start or End, and by using Divide to separate
or Link to combine.
For more information, see "Time Slice" on page 620 of
the PG.
5. Press the Save button.
The Save Samples & MS dialog box will appear.
Here you can save the time-sliced samples and the
multisample.
At this time, set the items in the Save With area to specify
the conversion destination for the program that will use
the samples and multisample, and for the performance
data (track or pattern) that will be used in SEQUENCER
mode to "recreate" the rhythm loop sample.
• If you want to create the performance data in a track:
Turn Program and Seq.Event On (checked)
Program: as desired (P000)
Track: On
Song: 010, Track: 01, Meter: 4/4
Start Measure: 001, Time: 008
