How to Add Notes in Vocaloid: A Complete Guide to Note Entry

Vocaloid is a vocal synthesis software that lets you build songs by entering musical notes and attaching lyrics to them — essentially programming a singing voice rather than recording one. If you're new to the platform, the note entry process can feel unfamiliar compared to traditional DAWs. Here's how it works, what tools are involved, and what variables shape the experience depending on your setup.

What "Adding Notes" Actually Means in Vocaloid

In Vocaloid, notes aren't just pitch markers — each note carries three core elements:

• Pitch — the musical note (C4, D#3, etc.)
• Duration — how long the note sustains
• Lyrics — the syllable or phoneme the voice sings on that note

This combination is what makes Vocaloid different from a standard MIDI editor. When you "add a note," you're placing a building block that the Vocaloid engine will render as a sung syllable. All three elements need to be set for the note to produce meaningful output.

The Piano Roll: Where Notes Live 🎹

All Vocaloid editing happens inside the Piano Roll editor, a grid where:

• The horizontal axis represents time
• The vertical axis represents pitch
• Note blocks are drawn directly onto the grid

To add a note, you switch to the pencil (draw) tool and click-drag on the grid. The length of your drag determines the note's duration. Once placed, you can resize notes by dragging their edges and reposition them by switching to the selection (arrow) tool.

Most versions of Vocaloid — including Vocaloid 5 and Vocaloid 6 — follow this same workflow, though the interface layout and available tools vary by version.

Step-by-Step: Adding Notes in the Piano Roll

1. Open or Create a Track

Launch Vocaloid and either open an existing project or create a new one. Select a Singer (the voice library you want to use) and add them to a track.

2. Enter the Piano Roll

Double-click the track or click the edit button to open the Piano Roll for that singer's part.

3. Select the Draw Tool

Click the pencil icon in the toolbar, or press the keyboard shortcut (usually D depending on your version). This activates note-drawing mode.

4. Click and Drag to Place a Note

Click on the grid at the desired pitch row and drag right to set the duration. Release the mouse to place the note.

5. Enter the Lyric

Once a note is placed, it will show a default lyric (often "a" or a language-specific default). Double-click the note to open the lyric input field and type the syllable you want. Press Tab to advance to the next note and enter lyrics sequentially — this is the fastest way to lyric-enter a full phrase.

6. Adjust Pitch, Duration, and Timing

Use the selection tool to drag notes to new pitches or new positions on the timeline. Drag the right edge to change duration.

Phonemes vs. Lyrics: Understanding the Input System

Vocaloid accepts input in two modes depending on the voice library's language:

Japanese voice libraries typically use romaji or hiragana input. English libraries accept standard English syllables, but pronunciation accuracy varies and phoneme editing is often needed. Other language libraries (Chinese, Spanish, Korean) follow their own phoneme systems.

If a note sounds unnatural or mispronounced, switching to phoneme view and editing individual phoneme symbols is often the fix.

Quantization and Grid Settings

Before drawing notes, check your quantization setting — this determines the minimum note length you can place. Common settings:

• 1/4 — quarter notes
• 1/8 — eighth notes
• 1/16 — sixteenth notes
• 1/32 — for fast passages or grace notes

A coarse quantize setting (like 1/4) can prevent you from placing short notes accurately. Fine quantize (1/32 or finer) gives more control but requires more precise clicking.

Variables That Affect Your Workflow

How smooth the note-entry process feels depends on several factors:

Vocaloid version — Vocaloid 5 and 6 have meaningfully different interfaces. Version 6 introduced an updated layout and some workflow changes. Users migrating between versions sometimes find shortcuts and menu locations have shifted.

Voice library language — Japanese libraries tend to have the most straightforward phoneme systems for beginners. English and other language libraries often require more phoneme correction after basic note entry.

Project tempo and time signature — Notes entered at high BPM with small quantize values demand more precise input. This becomes a real difference if you're working on fast-paced tracks versus slower ballads.

MIDI import vs. manual entry — You can import a MIDI file to pre-populate the note grid with pitches and timing, then layer in lyrics afterward. This skips manual note drawing entirely and can dramatically change the workflow for users adapting existing compositions.

Hardware and screen setup — The Piano Roll is detail-heavy. Working on a small screen or without a scroll wheel makes fine note placement noticeably harder than on a larger display with a mouse.

Working with Note Properties Beyond Pitch

Once notes are placed, Vocaloid exposes several per-note parameters: ✏️

• Velocity — affects the attack and "loudness" character of the note
• Dynamics (DYN) — controls volume over the note's duration via an automation lane
• Vibrato — can be set per-note with adjustable depth, rate, and delay
• Portamento — controls pitch sliding between notes

These aren't required for basic note entry, but they're what separates a mechanical-sounding render from something expressive. Most users start with note placement and lyrics, then layer in these parameters during refinement.

The entry process itself is consistent — but how much refinement a particular voice library or language requires, and how comfortable the workflow feels given your version and experience level, is where individual results start to diverge.
