Muting Segments You can mute or unmute individual segments using the Pitch & Warp tool. PROCEDURE 1. Move the mouse pointer over the bottom center of a segment. An x symbol appears. 2. Click the x symbol to mute the segment. The segment is grayed out to indicate that it is muted. 3. To unmute the segment, click the x symbol again. MIDI Input You can change the pitch on the fly by selecting the segment you want to change and pressing a key on your MIDI keyboard or using the Virtual Keyboard. PROCEDURE 1. After having corrected the segmentation, select the segment for which you would like to change the pitch. 2. Activate the Pitch & Warp tool and click MIDI Input . 3. Press a key on your MIDI keyboard or use the Virtual Keyboard to change the pitch of the segment. The pitch of the segment changes according to the note you play. The MIDI Input function has two modes: Still mode and Step mode . You can switch between them by [Alt]/[Option]-clicking on the MIDI Input button: In Still mode you can select individual segments by clicking on them and change their pit ch by pressing a MIDI key. You can also select several segments and press a MIDI key to change the pitch of several segments simultaneously. The pitch of the first selected segment is changed to the pitch of the MIDI note you play. The pitches of the other selected segment are changed by the same amount. In Step mode you can step through the segments by selecting the first segment that you woul d like to change and pressing a MI DI key. The next segment will automatically be selected afterwards. This allows you to work in a more creative way, for example, to develop completely new melody lines via MIDI.

RELATED LINKS Virtual Keyboard on page 210 Warping segments Time correction, i. e. warping at segment level, is useful if you want to align a musical accent to a certain position, or change or quantize the timing of single segments in monophonic vocal recordings. When warping audio segments, warp markers will be created. These are shown on the VariAudio and the AudioWarp tabs of the Sample Editor Inspector. IMPORTANTIMPORTANTIMPORTANTIMPORTANT Any correction of the segmentation must be applied before warping segments. To warp a segment, proceed as follows: PROCEDURE 1. On the VariAudio tab activate the Pitch & Warp tool. 2. To change the timing of a segment, move the mouse pointer over the start/end of the segment. The mouse pointer becomes a double arrow and the warp markers are displayed in the ruler. 3. Drag the start/end of the segment to the desired position. If the Snap button is activated, the segment border will snap to the grid. When you drag the segment border, warp markers are shown not only at the border but also at the adjacent segment borders to indicate which portions of the audio are stretched/affected. NOTE Warping a segment will also change the timing of the adjacent segments. NOTE Timing modifications introduced this way will not adapt to the project tempo. If this is what you want, use Musical Mode.

But when it comes to warping, any changes you wish to make must affect the waveform as a whole. You can of course change the segmentation to achieve this, but if you want to pitch your audio afterwards, this would affect also any non-tonal portions of the audio. If this is not what you want, proceed as follows: PROCEDURE 1. Activate the Pitch & Warp tool and activate the Snap button. In this example the beginning of the segment does not correspond to the beginning of the waveform.

The segment border snaps to the grid at the exact bar position. Now the beginning of the segment matches the beginning of the bar, but we want the beginning of the waveform to match the beginning of the bar: 3. Point at the warp handle displayed in the ruler so that it turns into a double arrow and drag it to the beginning of the waveform. The background is displayed in orange to indicate which part of the waveform is affected by the change. Now the beginning of the waveform matches the desired bar position. Editing warp markers can also be useful if you change the length of a segment that you have already warped. In this case, editing warp markers can help you synchronize your audio again.

Sample Editor VariAudio (Cubase Pro only) 485 Reset This pop-up menu at the bottom of the VariAudio tab allows you to reset the modifications you performed with the Pitch & Warp tool. It also lets you reset the changes you made in Segments mode by reanalyzing the audio and returning to the original segmentation. The following options are available: Pitch Changes If you select this option, pitch changes including micro-pitch modifications with the Tilt Micro Pitches tool are reset either for the selected segments (if available) or for the whole file. Warp Changes If you select this option, warp changes are reset. Pitch + Warp Changes If you select this option, pitch, micro-pitch, and warp changes are reset either for the selected segments (if available) or for the whole file. Reanalyze Audio If you select this option, the audio is reanalyzed and all your segmentation changes are reset. NOTE You can set up key commands for the reset and the reanalyze function in the Sample Editor category of the Key commands dialog. RELATED LINKS Key Commands on page 997 Listening to your modifications You can listen to the results of your modifications using the following methods: • By activating Acoustic Feedback on the toolbar. The segments are played back so that you can easily audition your pitch modifications while editing. • By using the Play tool on the toolbar. • By using the Audition and the Audition Loop tool on the toolbar. • By using cycle playback in the Project window.
Sample Editor VariAudio (Cubase Pro only) 486 If you want to compare the original to the modified audio (i. e. hear the audio without pitch or warp modifications), you have the following possibilities: • You can disable your pitch modifications by clicking the Disable Pitch Changes button on the VariAudio tab or by setting up and using the “VariAudio - Disable Pitch Changes” key command in the Key Commands dialog, Sample Editor category. • You can disable your warp modifications by clicking the Disable Warp Changes button on the AudioWarp tab or by setting up and using the “VariAudio – Disable Warp Changes” key command in the Key Commands dialog, Sample Editor category. RELATED LINKS Key Commands on page 997 Extracting MIDI You can extract a MIDI part from your audio. This is useful if you have an audio event with a certain tune and sound and you want to create an identical second tune with a MIDI instrument or VST instrument. The extracted MIDI part can also be used to print out notes from within the Score Editor or it can be exported as a MIDI file. Furthermore, you can convert the audio to MIDI notes containing Note Expression data which allows you to adopt the modulation data for individual notes. NOTE • Before extracting MIDI from your audio you should correct the segmentation. Otherwise, you will have to correct segmentation errors later in the MIDI part. Transition changes, tilting of the micro-pitch curve, Quantize Pitch settings, and pitch corrections will also be taken into account. • If your audio event references only a section of the audio clip, only this section will be extracted. The quality of the resulting MIDI data depends on the quality and the characteristics of your audio. To extract a MIDI part from your audio, proceed as follows: PROCEDURE 1. Open the audio file that you want to extract a MIDI part from in the Sample Editor. 2. Open the VariAudio tab. 3. Activate Segments mode. 4. Click the “Extract MIDI…” button. The “Extract MIDI” dialog opens.
Sample Editor VariAudio (Cubase Pro only) 487 5. On the Pitch Mode pop-up menu, specify which data should be included when extracting the MIDI part. The following options are available: 6. On the Volume Mode pop-up menu, specify how volume information from the audio is extracted to MIDI. The following options are available: 7. On the Destination pop-up menu, specify where the MIDI part will be placed. The following options are available: Option Description Just Notes and No Pitchbend DataOnly notes are included in the MIDI part. Notes and Static Pitchbend DataA pitchbend event is created for each segment. Select a pitchbend value from 1 to 24 in the Pitchbend Range field. When you are working with an external MIDI device, it might be necessary to set it to the same value. Notes and Continuous Pitchbend DataPitchbend events that correspond to the micro-pitch curve are created within the resulting MIDI part. Select a pitchbend value from 1 to 24 in the Pitchbend Range field. The setting should correspond to the value set on your MIDI device or the controlled VST instrument.Note that although the graphic representation of the pitchbend curve is smoothed, all pitchbend data is included. Notes and NoteExp Pitchbend CurveMIDI pitchbend events that correspond to the micro-pitch curve are created as Note Expression data for the resulting MIDI notes. Notes and NoteExp VST 3 Tuning CurveVST 3 events for the “Tuning” parameter are created as Note Expression data for the resulting MIDI notes. Note that this works only with a connected VST instrument that is compatible with Note Expression. Option Description Fixed Velocity All created MIDI notes get the same velocity. Select a velocity value in the Velocity field. Dynamic Velocity Each created MIDI note gets an individual velocity value according to the amplitude of the audio signal. Volume Controller CurveA continuous volume controller curve is created within the MIDI part. You can select the MIDI controller to be used for the curve in the MIDI Controller field. NoteExp Volume Controller CurveMIDI volume controller events are created as Note Expression data for the resulting MIDI notes. NoteExp VST 3 Volume CurveA VST 3 volume curve is created as Note Expression data for the resulting MIDI notes. Note that this works only with a connected VST instrument that is compatible with Note Expression. Option Description First Selected TrackThe MIDI part will be placed on the first selected MIDI or instrument track. Note that any MIDI parts from previous extractions that are on this track will be deleted.
Sample Editor Generating Harmony Voices for Monophonic Audio (Cubase Pro only) 488 NOTE If you have opened the Sample Editor from the Pool and the audio file is not part of your project, the MIDI part will be inserted at the beginning of the project. 8. Click OK. RESULT A MIDI part is created according to the specified settings. You can also use a key command to extract a MID I p ar t f r o m y o u r au d i o . I n th i s c a s e no dialog opens and the settings that were used for the previous extraction are used. RELATED LINKS Exporting and importing standard MIDI files on page 1021 Note Expression on page 792 Segments mode on page 472 Key Commands on page 997 Generating Harmony Voices for Monophonic Audio (Cubase Pro only) You can quickly harmonize monophonic audio using the “Generate Harmony Voices” function on the Audio menu. This function automatically performs a VariAudio analysis, copies your event the specified number of times, and adds the resulting voices on separate tracks in the Project window. If you add a chord track to your project, the pitches of the resulting voices are altered to match the voicing of the chord track. PROCEDURE 1. Import a monophonic audio file. 2. In the Project window, select the audio event. New MIDI Track A new MIDI track will be created for the MIDI part. Project Clipboard The MIDI part is copied into the clipboard so that you can insert it at the desired position on a MIDI or instrument track in the Project window. Option Description
Sample Editor Flattening realtime processing 489 3. On the Audio menu, select “Generate Harmony Voices…”. 4. Specify the number of voices that you want to create and enter a value for the vibrato reduction. RESULT The new voices follow the soprano, alto, tenor, and bass voices from the chord track voicing. To open all voices in the Sample Editor, activate the “Open Sample Editor After Completion” option. This allows you to view and edit the different voices. NOTE If you generate harmony voices without the chord track, the generated VariAudio segments of voice number 1 (soprano) are transposed three semitones upwards in relation to the original audio. The segments of voice numbers 2, 3, and 4 (alto, tenor, and bass) are transposed three, six, and nine semitones downwards. RELATED LINKS Chord Functions on page 814 Handling Several Audio Events (Cubase Pro only) on page 448 Flattening realtime processing You can “flatten” realtime processing at any time. This can be done to serve two purposes: to reduce the CPU load and to optimize the sound quality of the processing. Also use this function before applying any offline processing. When the flatten processing is applied, a copy of the original file is automatically created in the Pool so that the original audio clip remains intact. The flatten function takes the following into account: • Warp modifications, even when Bypass is activated. After the flattening, your Warp markers will be lost. However, you can undo this function as usual. • VariAudio pitch modifications, even when Bypass is activated. After the flattening, your VariAudio data will be lost. However, you can undo this operation. •Event transpose
Sample Editor Flattening realtime processing 490 PROCEDURE 1. Select the audio events that you want to process. 2. On the Audio menu, open the Realtime Processing submenu and select the Flatten command. Provided that the time stretching factor is not outside the range of 0.5 and 2, a dialog opens where you can select an algorithm for the processing. If the audio has been transposed, the dialog also contains the “Formant Correction” option. You can activate this, for example, if you want to avoid a “chipmunk voice” effect. 3. Select an algorithm preset and click OK. After the processing, any loop that was previously stretched in realtime or had been pitch shifted will play back exactly the same, but Musical Mode will be deactivated and the realtime pitch shifting will be set to 0. NOTE Instead of the Flatten menu command, you can click the Flatten button on the Process tab of the Sample Editor. RESULT The audio clip is now like any standard audio clip before applying realtime processing, i. e. it does not follow tempo changes. The flattening processing function is best used when you have determined the tempo or key of a project. If you want to adapt the audio to a new key or tempo after flattening, it is better to revert to the original audio clip rather than to process the already processed file again. RELATED LINKS Free Warp on page 457 Warping segments on page 482 Changing the pitch on page 476 Transposing individual parts or events using the info line on page 276 Selecting an algorithm for the flattening When you flatten the realtime processing, you can use the MPEX 4 algorithm or the Realtime algorithm to process the audio. The MPEX 4 algorithm may produce better sound quality than the realtime processing. The Realtime algorithm corresponds to the algorithm preset selected on the Sample Editor toolbar. NOTE If you introduced VariAudio pitch modifications, the MPEX presets will not be available and the algorithm preset “Standard – Solo” is used automatically.
