After restoring the system following a computer failure or replacement, an authorization error says that the corresponding VOCALOID component cannot be found.

If you restore a system using a backup or migration feature such as Time Machine, Migration Assistant, a backup tool, or disk cloning, the copied VOCALOID product installation may not be recognized correctly. In this case, uninstall all installed VOCALOID products, and then reinstall and authorize them. Uninstallation locations Windows Start > Settings > Apps > Apps & features macOS Applications > VOCALOID7 > Uninstaller If uninstallation fails, reinstall the VOCALOID product over the existing installation, and then try authorization again.

I entered notes and played them, but I cannot hear any sound.

Several factors may cause this issue. Check the following in order. 1. Turn off Mute/Solo in Track Editor. 2. If the track or master fader in the Mixer is at the bottom, raise it to 0 dB. 3. Turn off all Mute/Solo settings in the Mixer. 4. Check that DYNAMICS in the control parameters and track automation are not set to zero. 5. An unauthorized voicebank will not produce sound. Select an authorized voicebank. You can check its authorization status in VOCALOID Authorizer. 6. Check that the correct audio device is selected in Preferences. 7. If you imported a VPR or VSQX file containing lyrics for a different language than the selected voicebank, sound may not play even though the lyrics are displayed. Enter appropriate lyrics again.

Very short notes or short gaps between notes do not produce the intended pronunciation.

As with human singing, VOCALOID7 requires a certain amount of time to pronounce a note and transition to the next sound. Notes that are extremely short or separated by rests that are too short may therefore not be pronounced as intended. Try the following: Make the note slightly longer. Make the rest between notes slightly longer.

I entered phonetic symbols directly, but the note no longer produces sound.

When entering multiple phonetic symbols for one note, separate each symbol with a space. Entering an unsupported phonetic symbol also results in silence. To restore the original pronunciation, select the note, right-click it, and select Reset Lyrics.

The start of the song is out of sync when I use VOCALOID7 VSTi/AU.

To reproduce natural human singing, VOCALOID7 may begin synthesizing audio slightly ahead of the note timing, depending on the lyrics. If the data begins at bar 1, beat 1 of the DAW project, synthesis may not work correctly. Add about two blank bars before the start of the song.
