The Sample Editor
4. Verify the Tempo and Bars values in the toolbar.
5. On the Hitpoints tab, click on the Slice & Close button
or select “Create Audio Slices from Hitpoints” from the
Hitpoints submenu on the Audio menu to create audio
slices from the hitpoints.
The following happens:
• The Sample Editor closes.
• The audio event is “sliced” so that the sections between
the hitpoints become separate events, all referring to the
same original file.
• The audio event is replaced by an audio part, containing
the slices (double-click the part to view the slices in the Au-
dio Part Editor). If you edited a clip from the Pool, you need
to drag it to an audio track to get a part with the slices.
• The loop is automatically adapted to the project tempo.
This takes the loop length you specified into account: e.g., if
the loop was one bar long, the part is resized to fit exactly
one bar in the Cubase AI tempo, and the slices are moved
accordingly, keeping their relative positions within the part.
• In the Pool, the sliced clip is shown with a different icon.
Dragging the sliced clip from the Pool to an audio track will create an audio
part with the slices adapted to the project tempo, just as above.
6. Activate cycle playback on the Transport panel.
The loop should now play back seamlessly at the tempo set in the project!
• If the project tempo is lower than the original tempo of
the loop, there may be audible gaps between each slice
event in the part.
This can be remedied by using the Close Gaps function on the Advanced
submenu of the Audio menu, see “Close Gaps” on page 136. You should
also consider activating auto fades for the corresponding audio track –
fade-outs set to about 10ms will help eliminate any clicks between the
slices when you play back the part. See “Fades, crossfades and envelo-
pes” on page 62 for details.
• If the project tempo is higher than the loop’s original
tempo, you may want to activate auto crossfades for the
track.
You can use the Close Gaps functions in this case as well, see “Close
Gaps” on page 136.
The slices in the Audio Part Editor. Here, the project tempo was higher
than the loop’s original tempo – the slice events overlap slightly.
Setting hitpoints manually
If you cannot get the desired result by adjusting the sensi-
tivity, try to set and edit hitpoints manually.
1. Zoom in on the waveform at the point where you wish
to add a hitpoint.
2. Select the Edit Hitpoints tool to audition the area and
make sure that the start of the sound is in view.
• Activate Snap to Zero Crossing on the Sample Editor
toolbar.
By finding zero crossings in the waveform (positions where the amplitude
is close to zero), manually added slices won’t introduce any clicks or pops.
All hitpoints calculated by the program are automatically placed at zero
crossings.
3. Press [Alt]/[Option] so that the mouse pointer changes
to a pencil tool and click just before the start of the sound.
A new hitpoint appears. Manually added hitpoints are locked by default.
• If you notice that a hitpoint was either placed too far
away from the start of the sound or too far into the sound,
you can move it by clicking on the hitpoint handle and
dragging it to the new position.
!
When you create slices, all events containing the ed-
ited clip will also be replaced.
!
Only when the audio tempo has been defined and
the audio grid matches the project tempo, your slices
will be straight (quantized).
!
“Snap to Zero Crossing” may alter the timing. In
some cases it might therefore be better to deactivate
it. However, if you create slices afterwards, auto
fades will be necessary.
