3. Inputting Lyrics and Melody

With your software and voicebanks ready, you can begin the creative process. This involves inputting the lyrics and melody for your song.

• Lyrics: You'll type the lyrics directly into the software's editor. The software then maps these lyrics to the chosen melody.
• Melody: The melody can be composed within the Vocaloid software itself using its piano roll editor, or it can be imported from other Digital Audio Workstations (DAWs) like Ableton Live, FL Studio, or Logic Pro.

This is where the magic starts to happen. As you input the notes and lyrics, the Vocaloid engine synthesizes the vocal performance based on the selected voicebank and the parameters you set.

4. Fine-Tuning and Editing

The initial synthesized vocal output is often just the starting point. To achieve a truly professional and expressive performance, you'll need to fine-tune and edit the vocal track. This is where the power of Vocaloid's editing tools comes into play.

• Pitch and Tone Adjustment: You can meticulously adjust the pitch of each note, ensuring perfect intonation. You can also modify the tone of the voice, making it brighter, darker, or more resonant.
• Vibrato and Expression: Vocaloid allows you to add and control vibrato, a subtle oscillation in pitch that adds warmth and expressiveness to singing. You can also manipulate parameters related to breathiness, growls, and other vocal effects to convey emotion.
• Articulation and Dynamics: Fine-tuning the articulation of syllables and words is crucial for clarity and naturalness. You can also adjust the dynamics, controlling the volume and intensity of the vocal performance to create emphasis and emotional impact.
• Cross-Synthesis (VOCALOID 4 and later): This advanced feature allows you to blend two different voicebanks together, creating unique hybrid vocal sounds that are truly one-of-a-kind.
• Growl and Breath: Newer versions of Vocaloid offer dedicated controls for adding growl and breath sounds, further enhancing the realism and expressiveness of the synthesized vocals.
