Select Voice Library

Click the Library pull-down to view a list of available Voice Libraries. If there are Voice Libraries that have not yet been downloaded, Download buttons will appear on their right side.

Some Voice Libraries may not be supported because the version of the Editor you are using is not up to date.
In such a case, click the button displayed to go to the Download page. Download and install the latest version of VoiSona.
After you launch the updated VoiSona, Download buttons for the Voice Libraries will now appear.

Tempo, Beats, Key Signature and Dynamic Symbols Editing

Buttons to display/hide their editor areas.
By double-clicking on each editor area, a symbol can be inserted and edited.
Specifying the correct key signature is critical in getting good singing results from the singer.
Specifying the dynamics symbols gives the singer a modulated voice.
* Depending on the voice library or the score, it may be difficult to tell the effects of dynamics symbols.

Global Parameters

Edit parameters that apply to the entire song.
・TUNE: Fidelity to the pitch of the notes. The lower the value, the more the note strays from the correct pitch. The higher the value, the closer the note is to the correct pitch.
・VIA: Amplitude of vibrato. Raising the slider makes the vibrato wider.
・VIF: Vibrato frequency. Lowering the slider results in a soft vibrato, while raising it makes it narrower.
・ALP: Voice quality. Lowering the slider makes the voice sound more childlike, while raising it makes the voice sound more mature.
・HUS: Degree of huskiness. Increasing the value makes the voice huskier.

Standard Pitch

Edit the standard pitch of the entire song.

Freeze Track

Normally, voice synthesis processing is performed in real time during playback. However, computing resources may become overloaded on some PCs, resulting in choppy playback.
In such a case, the Freeze function can reduce the load during playback by performing voice synthesis processing in advance of playback.

When you click the Freeze button, the voice synthesis process begins. Depending on your PC’s capabilities, this may take some time.

When voice synthesis processing is complete, the Freeze button becomes orange, indicating that the track is frozen.

Transfer MIDI from DAW

You can transfer MIDI information entered in a DAW to VoiSona.
Note that only the MIDI information of the playback section will be reflected in VoiSona.

Audio input

With VoiSona Song Editor (Effects), besides synthesizing audio effects, you can add a singer’s voice to the audio input by clicking the Audio Input button to turn it ON.
(These features are currently in test function. They are available only to current subscribers of paid libraries.)
* When audio input is enabled, some functions such as PIT and HUS parameters are disabled.
* 48 kHz is recommended for the audio input function. If a sampling rate other than 48 kHz is set, the synthesized sound output will be slightly delayed.

Select notes together at once to move, copy or delete them at the same time.

Splitting and merging notes

To split or join notes, select the Split/Join tool from the Tools menu.
Click on the position in the note where you want to split.

To join notes, click on the end of a note to join it with the note before or after it.

Lyric Syllables Entry

Double-click on a note to enter lyric syllable(s) for that note. Press Tab to move to the next note, or Shift+Tab to move to the previous note.

You can also enter English lyrics.
If you want one lyric syllable to stretch across multiple notes, add a hyphen to the syllable that follows a note.(Example: “li” + “-ke” => “like”)
By right-clicking on the piano roll and turning on "Auto Split English Lyrics," English words are automatically split by syllable and assigned to multiple notes.

Bulk Lyric Syllables Entry

Clicking the “Bulk Lyrics Entry” button opens the “Bulk Lyrics Entry” panel.

You can enter lyric syllables to be assigned to multiple notes at once.
If the “Separate with space” option is selected, each group of lyric syllables, separated by space, is assigned to one note.
If “One note, one character” is selected, each character/syllable is assigned to one note.

You can also enter English lyrics.
If you want one syllable to stretch across multiple notes, prepend a hyphen to the syllable that is stretched to the next note.

Special Symbols

Vowel drop
You can drop a vowel by adding full-width ’(apostrophe) after the lyric syllable.
For example, if the lyric syllables are vocalized as “y, e, s, u,” adding ’(y, e, s, u ’) causes the “u” to be dropped, and the lyric syllables are vocalized as “y, e, s”.

Indicate falsetto by including half-width “$”, full-width “$” or full-width “※” in the lyrics.

  • * Depending on the voice library and the pitch of the voice, it may not be easy to create a falsetto.

Other Special Symbols
You can bring out each singer’s distinctive vocal characteristics by using “training labeling symbols.”
VoiSona achieves highly accurate voice libraries by training AI models with recorded data labeled with each voice provider’s singing style characteristics.
In VoiSona, you can add these labeling symbols to lyrics to bring out the special characteristics of the voice provider’s singing style.

  • * Depending on the voice library and its version, the lyrics, the pitch of the voice, etc., the desired characteristic may not be readily produced.
  • * Because labelling is a mechanism for improving the accuracy of the training model, there may be cases where the characteristic cannot be produced.
  • * Even if a vocal characteristic is not specified (shown as blank) for the voice library, entering a symbol may cause some changes in the synthesized voice.

Frequently Asked Questions (FAQ)

Q. Can I use VoiSona Voice Libraries on CeVIO AI and CeVIO Creative Studio?
No, Voice Libraries released for VoiSona can be used only on VoiSona.
Due to popular request, we are considering cross-platform compatibility of Voice Libraries between VoiSona and sister brand CeVIO.

Q. Can I change my login password?
To change your login password, click the "Change Password" link on the account page.

Q. I want to delete my VoiSona account.
Please contact us using the Contact Us page.

Q. I cannot download a voice library.
See the “Using VoiSona as Standalone App” > “Select Voice Library” section on this webpage and try again.

Q. Selecting a voice library failed.
Delete the voice library, re-download it, and try again.

Q. Shortcut keys do not work.
Keyboard shortcuts may not work on Apple silicon-equipped Macs when running VoiSona on Logic Pro or GarageBand.
Running the DAW in Rosetta mode works.
In addition, if you are using VoiSona as a plug-in on your DAW, and the DAW has shortcut keys that are the same as VoiSona’s, the DAW’s shortcut keys may take priority and negate the VoiSona’s shortcut keys.
In such a case, open VoiSona’s Preferences, go to the Shortcuts tab, and change the affected shortcuts.

Q. Keyboard shortcuts using the Alt key do not work.
In some DAWs (e.g. Studio One), keyboard shortcuts using the Alt key do not seem to work with plug-ins.
In such a case, open VoiSona’s Preferences, go to the Shortcuts tab, and change Alt key shortcuts to keystrokes that do not require the Alt key.

Q. Is it possible to enter extremely short notes such as a sixty-fourth note?
You can only enter up to a thirty-second note. Use the Timing (TMG) adjustment window to edit vocal timing in finer detail.
If you turn ON the eye icon on the volume (VOL) tab, the volume line is displayed. This makes it easier to make TMG adjustments.

Q. The maximum number of activations is reached when I try to use GarageBand.
You can activate VoiSona on up to two PCs, and you can use multiple DAWs on one PC. However, unlike other DAWs, GarageBand is recognized as a separate PC.
To resolve this issue, go to your VoiSona account webpage and deactivate registered PCs before launching GarageBand.

Q. I can’t use a downloaded voice library on GarageBand.
Change macOS privacy settings: Apple menu > System Preferences, then click Security & Privacy > General. In Allow downloaded applications to run, choose allow dylib that begin with ts_.
Launch GarageBand again after changing these settings.Although dylibs are signed, GarageBand has stricter security than other DAWs. Permission is required even for signed dylibs.
You may need to follow these steps again when you download and use a new voice library on GarageBand.

Q. Is it possible to specify the playback start position in the Song Editor?
Yes, you can start playback from a specified position with the following steps.
First, click on the Ruler on the Song Editor window (the area where the dynamic and key signatures are displayed) to specify the playback start position.
Next, click the Playback button on the left side of the Song Editor window. The audio will play from that position.
However, in many DAWs the Song Editor window is not linked to the DAW’s playback start position. When you play back on the DAW side, the position you specified in the Song Editor window may be ignored (even if you start playback by using the space key).

Q. How do I cancel my voice library subscription?
Please turn off the auto-renewal of your voice library subscription.
You can turn off auto-renewal by going to the license page (login required) and clicking the Cancel Reservation button for the voice library subscription.
Once auto-renewal is turned off, the license will change to show “Status: Subscription Cancellation Reserved” and will be cancelled when the subscription expires.
You can continue to use the voice library until the expiration date.

Q. I am experiencing activation failure when using both "VoiSona" and "VoiSona Talk".
Due to an update, the method for acquiring the hardware information necessary for activation has changed.
If you are using both "VoiSona" and "VoiSona Talk", we kindly ask you to update both software.
If activation fails after updating, please deactivate the old activation information on your account page.

Q. How can I use the "Waveform Generator Prototype A"?
The experimental feature "Waveform Generator Prototype A," available exclusively in the Japanese song voice library "Chis-A," has been discontinued as its role concluded with the release of "Chis-A" version 2.0. Therefore, the functionality was removed in the version following 1.8.2 of the Song Editor.
In order to reproduce voice waveforms created using the "Waveform Generator Prototype A," the Song Editor version 1.8.2 can be downloaded for the time being from the link at the bottom of the download page.
