Generating Synthetic Vocal

Your Melody or Soloist track with lyrics can be rendered to a vocal audio track, with built-in support for the popular online vocal synth “Sinsy.”

To access this feature, you should first enter melodies and note-based lyrics to the Melody or Soloist track. If no lyrics are present, you can still generate a vocal synth using the syllable of your choice (e.g. la la la).

Press the [Vocal Synth] button on the Notation window toolbar or right-click on the Notation window and select either of the Vocal Synth menu items.

With the manual mode, Band-in-a-Box creates a Sound.XML file, which you need to upload to the Sinsy server. When the Sinsy has generated an audio file with a vocal synth, import it to Band-in-a-Box.

Normally, you would use the auto mode, which does this process automatically for you. When you choose an auto mode, the Generate Synthetic Vocal dialog will open.

Language: The choice is English or Japanese. Select English unless your lyrics are entered in Japanese.

Vocalist: Choose one of the female or male vocalists. If the language is set to English, you can only select an English singer.

Gender Parameters: You can adjust the gender of the voice in a range from -0.8 to +0.8. Higher values are more masculine. The default is 0.55.

Vibrato Intensity: This controls the amount of vibrato in the voice. The range is from 0 to 2. The default is 1.

Pitch Shifting: This setting will shift pitch in semitones. The range is from -24 to +24. A setting of -12 would be down one octave. The default is 0.

For Melody notes with no lyrics use: If the track does not include lyrics, you can enter a syllable (.e.g. la) to use for notes with no lyrics. (Note: If you select a Japanese vocalist, you need to enter a Japanese syllable.)

When you press [OK], your song will be sent automatically to the Sinsy server and will be rendered to a vocal synth. This may take a few minutes.

When the vocal synth has been generated and imported to the Audio track, a flash message shows, and the Mixer expands to show the Audio panel.



Press the [Play] toolbar button to hear the vocal synth singing your song!
