Sampling and editing in Sampling mode
135
Set “Resolution” as desired, and specify the tempo
BPM value.
The grid is displayed according to the playback
pitch at the base key (the key shown in blue for
“Keyboard & Pad”). You can select the base key by
holding down the ENTER switch and playing a key.
Press the base key to play the sample, and press the
TAP TEMPO switch at quarter-note intervals along
with the phrase. This will enable Tap Tempo and
specify the tempo.
2. Set the end address “End” so that it coincides with
a grid line.
This will make the loop length match the BPM.
If looping is on, the grid is displayed beginning at
“Loop Start.” If looping is off, the grid is displayed
beginning at “Start.”
3. If you want to hide the grid display, uncheck the
“Grid” option.
Using Time Slice to divide a sample, and
playing it in Sequencer mode
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-slices 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 OASYS,
or load them in Disk 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 133).
2. Access the P2: 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 BPM, set “Source BPM.”
If you do not know the BPM, set “Beat” 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 switch
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
