The Sample Editor
Realtime pitch-shifting of audio
events
Audio events can be pitch-shifted in realtime just like MIDI
events. The process is very simple:
1. Open the audio event in the Sample Editor and open
the Playback tab.
2. Set a value in the corresponding field in the Transpose
section.
The value range is up/down two octaves in semitone steps.
3. Press [Enter].
The audio event is now transposed to the set value using pitch-shift.
4. If a root key is specified or if the Transpose track has
been added, you can click the Follow Global mode to ac-
tivate/deactivate Global Transpose.
Event transpose will be added to the Global transpose value.
For more information on the transpose functions and the
Transpose track, see the chapter “The Transpose func-
tions” on page 111.
• You can also select the audio event in the Project win-
dow and change the Transpose value on the infoline. In
this case, you can also fine-tune selected audio events in
cent steps (100ths of a semitone) by entering a value in
the Finetune field to the right.
Flattening the realtime processing
You can “flatten” any realtime processing at any time. This
can be done to serve two purposes; to conserve CPU
power and to optimize the sound quality of the processing.
• Select the audio event(s) you wish to process and se-
lect “Flatten Timestretch and Transpose” from the Real-
time Processing submenu of the Audio menu.
You should also use this function before applying any offline processing.
When the flatten processing is applied, a copy of the original file is auto-
matically created in the Pool so that the original audio clip remains intact.
Selecting an algorithm for the flattening (Cubase only)
When you flatten the realtime processing, you can use the
MPEX 3 algorithm to process the audio, which may pro-
duce better sound quality than the realtime processing.
This is also the only way to achieve polyphonic formant
conserving pitch-shifting, apart from offline processing.
Proceed as follows:
1. Select the audio event(s) you wish to process.
2. Click the Flatten button on the Playback tab of the
Sample Editor Inspector, or select “Flatten Timestretch
and Transpose” from the Realtime Processing submenu of
the Audio menu.
A dialog appears where you can select an algorithm for the processing.
You can either select the MPEX 3 algorithm, which will produce the high-
est sound quality, or the Realtime algorithm which is much quicker but
will not improve the audio quality of the processing (although it will
lessen the CPU load).

Audio and MIDI events cannot be transposed simul-
taneously.
