Opening the Piano Roll and Placing Your First Note

To add notes in Vocaloid 3, open the piano roll editor in your DAW (Digital Audio Workstation) — the grid where you see time running left to right and pitch running bottom to top. Click or drag in the empty space to create a note. The note will snap to the nearest grid line by default, which keeps timing clean. You can adjust the grid size in your DAW's settings if you want finer control.

Each note you place appears as a colored block. The left edge marks when the note starts, the right edge marks when it ends, and the vertical position shows the pitch. A note at the bottom of the grid is a low pitch; a note at the top is high. You can click and drag the edges of any note to make it longer or shorter, or drag the whole note left or right to move it in time.

Key Takeaways

  • Click or drag in the piano roll grid to create notes; they snap to the grid by default to keep timing aligned.
  • Drag the left or right edge of a note to change its length, or drag the note itself to move it earlier or later in time.
  • Double-click a note to open the note properties panel, where you can set exact pitch, timing, and length by typing numbers.
  • Use the velocity slider in the note properties to control how hard the note is sung — higher velocity sounds more emphasis.
  • The phoneme editor lets you control which syllables the voice sings on each note, overriding Vocaloid's automatic guess.

Adjusting Note Length and Timing with Precision

If you need exact control, double-click any note to open its properties panel. Here you can type the exact start time, length, and pitch instead of dragging. This is faster when you are working from sheet music or a MIDI file and need notes to land on exact beats. The properties panel also shows you the note's velocity — how hard the note is sung — which you can raise to add emphasis or lower to make it softer.

You can also select multiple notes at once by clicking and dragging a box around them, then move or resize them all together. This is useful when you want to shift a whole phrase earlier or later, or when you want to raise or lower a group of notes by the same amount. Hold Shift and click individual notes to add or remove them from your selection.

Controlling Pitch and Vibrato

The pitch of each note is set by its vertical position in the grid. The piano roll shows note names on the left side — C, D, E, and so on — so you can see exactly which note you are placing. If you want to add vibrato (a wavering pitch effect), click the note and look for the vibrato controls in the properties panel. You can adjust how fast the pitch wavers and how much it wavers.

Vocaloid 3 also lets you draw pitch curves between notes. This creates smooth pitch slides instead of jumping from one note to the next. Look for a curve tool in your DAW's toolbar, or check the Vocaloid menu for pitch bend options. A gentle curve sounds natural; a steep curve sounds like a slide whistle.

Setting Phonemes and Syllables

By default, Vocaloid 3 guesses which syllables to sing on each note based on the lyrics you entered. Sometimes it guesses wrong — it might split a syllable across two notes when you wanted it on one, or it might not recognize a word. To fix this, open the phoneme editor. This is usually a separate panel or window that shows each note with its assigned phoneme (the sound the voice makes).

Click on a note in the phoneme editor to see what sound Vocaloid assigned to it. You can click a dropdown menu to choose a different phoneme from a list. If you want a note to be silent, choose the rest symbol. This level of control is what makes Vocaloid sound natural instead of robotic — spending time on phonemes is worth it for any part you plan to share.

Using MIDI Input to Speed Up Note Entry

If you have a MIDI keyboard connected to your computer, you can play notes into Vocaloid 3 instead of clicking them one by one. Enable MIDI input in your DAW, then play the melody on your keyboard while the transport is rolling. Each note you play will be recorded into the piano roll. You can adjust timing and length afterward if your playing was not exact.

You can also import a MIDI file directly into Vocaloid 3. Most DAWs let you drag a MIDI file into the piano roll, or you can use File > Import MIDI. Vocaloid will place notes based on the MIDI data, and you can then adjust them and add lyrics. This is much faster than typing in notes by hand if you already have a melody recorded or composed elsewhere.

Editing Note Velocity and Expression

Velocity controls how hard or soft a note is sung. In the piano roll, you can see velocity as a thin bar below each note — taller bars mean higher velocity. Click and drag these bars up or down to change how much emphasis each note gets. Higher velocity on important words makes them stand out; lower velocity on connecting words makes them blend.

You can also use the velocity lane at the bottom of the piano roll to draw velocity curves across a whole section. This lets you create a gradual crescendo (getting louder) or decrescendo (getting softer) without adjusting each note individually. Select the pencil tool and draw in the velocity lane to create the shape you want.

Troubleshooting Common Note Entry Problems

If notes are not snapping to the grid where you expect, check your grid size setting. A very fine grid (like 1/32 notes) makes it hard to place notes quickly; a coarser grid (like 1/4 notes) snaps notes to obvious beat positions. You can usually change this with a dropdown menu in the toolbar or by right-clicking the grid itself.

If a note sounds wrong or cuts off early, check that the note length is long enough for the syllable. Vocaloid needs time to sing each sound — a note that is too short will sound clipped. Also check the phoneme assignment; if the wrong sound is assigned, the note will sound like a different word. If notes are overlapping and creating a muddy sound, make sure each note ends before the next one starts, or use the overlap controls in the phoneme editor to blend them smoothly.

Frequently Asked Questions

Can I copy and paste notes in Vocaloid 3?

Yes. Select the notes you want to copy by clicking and dragging a box around them, then press Ctrl+C (or Cmd+C on Mac). Click where you want to paste and press Ctrl+V. The notes will paste at the same relative positions, so if you copied a phrase, it will paste as the same phrase at a new location.

How do I delete a note?

Click the note to select it, then press Delete or Backspace. You can also right-click the note and choose Delete from the menu. To delete multiple notes, select them all with a box, then press Delete.

What is the difference between a note and a phoneme?

A note is the pitch and timing — where the melody goes and how long each sound lasts. A phoneme is the actual sound the voice makes on that note. One note can have one or more phonemes, depending on how many syllables fit on that pitch.

Can I make notes longer or shorter after I place them?

Yes. Click the right edge of the note and drag it left to shorten or right to lengthen. You can also double-click the note, open its properties, and type an exact length in milliseconds or beats.

Why does my note sound cut off or rushed?

The note is probably too short for the syllable. Vocaloid needs time to pronounce each sound fully. Try lengthening the note by dragging its right edge, or check the phoneme editor to make sure the right sound is assigned — a wrong phoneme will always sound rushed or wrong.
