VELCANTO is a vocal plugin that turns a streamer's singing voice into a voice made for singing, with knobs free of technical terms. A sister product of VELVOX (for the speaking voice).

1. Overview

VELCANTO is a vocal plugin designed for streamers who sing. No audio engineering knowledge is needed. By adjusting knobs free of technical terms, it shapes a streamer's singing voice into a voice made for singing.

• Simple operation with zero technical jargon: Without using any difficult audio terms, you can intuitively shape your singing voice with SHINE ("Cuts through"), SPACE ("Hall"), and ECHO ("Echo").
• Zero latency: The free edition processes audio with zero latency.
• Lightweight performance: Runs lightly on the same PC as your streaming software.
• Automatic distortion prevention: Output levels are kept in check automatically at the output stage so your sound will not clip no matter how high you turn the knobs.

3. Installation

Installation (Windows)

1. Extract the downloaded ZIP file.
2. Copy the VELCANTO.vst3 folder to the following location:
   C:\Program Files\Common Files\VST3\
3. Launch your DAW and perform a plugin rescan (if you copy while the DAW is running, it may not be detected immediately).

Installation (Mac)

1. Extract the downloaded ZIP file.
2. Copy VELCANTO.vst3 to ~/Library/Audio/Plug-Ins/VST3/, and copy VELCANTO.component to ~/Library/Audio/Plug-Ins/Components/ (where ~ represents your home folder. In Finder, open the "Go" menu, choose "Go to Folder...", paste the path, and press Return. If the folder does not exist, create it).
3. Open Terminal (Applications → Utilities → Terminal), paste the following 3 lines one by one, and press Return for each:

   cd ~/Library/Audio/Plug-Ins
   xattr -dr com.apple.quarantine VST3/"VELCANTO.vst3"
   xattr -dr com.apple.quarantine Components/"VELCANTO.component"

4. Launch your DAW and perform a plugin rescan (if you copy while the DAW is running, it may not be detected immediately. If AU does not appear in Logic Pro or other DAWs, restart your Mac).

Uninstallation

[Windows] Delete the copied VELCANTO.vst3 folder.
[Mac] Delete the copied VELCANTO.vst3 and VELCANTO.component files.

4. Using with OBS

Because OBS cannot load VST3 plugins directly, install the free OBS plugin "atkAudio Plugin" and run VELCANTO inside it. OBS Studio 31.1.1 or later (64bit) is required.

1. Install the installer for your OS from the atkAudio Plugin download page.
2. Launch OBS and open "Filters" for your microphone audio source.
3. Click "+" and add "atkAudio Plugin Host".
4. Click "Open Plugin Settings", and under "Options", select "Scan for new or updated VST3 plugins" to detect installed plugins (first time only).
5. Select VELCANTO from the list, click "Load Plugin" to load it, open the window, and turn the knobs.

* In a DAW (such as Ableton Live), simply insert it as a standard effect on your vocal track.

5. The screen

Header bar (top)

• Logo & version: Displays the logo and version at the top left of the window.
• Preset bar: Located to the right of the logo. Select presets according to the scene.
• SING button: Located at the right of the header with a PRO badge (Pro feature).

Presets

Presets can be selected to fit the scene. You can adjust the knobs freely after selecting a preset. In the free edition, saving is not available (SAVE and DEL cannot be used).

• F01 DEFAULT: If in doubt, start here (default values).
• F02 NATURAL: Subtle adjustment that stays close to your natural voice.
• F03 BALLAD: For gentle, mellow songs; longer acoustic space.
• F04 UPTEMPO: For fast-paced songs or thick backing tracks; brings the voice forward.
• F05 KARAOKE: Karaoke-style echo.

InfoBar

• Located right below the header. When you hover over a knob, it explains what that knob improves (displays in English on an English OS, and in Japanese on a Japanese OS).

VOICE "Shape your vocal"

• SHINE "Cuts through": Turn up if your singing voice gets buried under the backing track. Adds luster and tension to your singing voice. While the indicator dot below the knob ("Taming S sounds") is lit, it automatically softens harsh S sounds so they never hurt the ears. Keep this moderate when used together with VELVOX.
• SPACE "Hall": Adds the acoustic space of singing in a hall. Turning it up makes the space wider and ring longer.
• ECHO "Echo": Karaoke echo. Turning it up makes the repetitions louder and repeat longer. The repetitions also carry acoustic space.

TUNE "Pitch" and SING "Vocal"

• Features of the Pro edition. While visible on the screen in the free edition, they have a PRO badge and cannot be adjusted. Hovering the mouse over them displays an explanation of the Pro edition features.

OUT "Voice level" meter

• If the bar stays within the target zone while singing, your voice is at an easy-to-hear volume for streaming.
• Output levels are kept in check automatically at the output stage so your sound will not clip no matter how high you turn the knobs.

6. How to use

1. Play your favorite song and sing along; if your voice gets buried under the backing track, turn up SHINE.
2. Turn up SPACE if you want acoustic space, or turn up ECHO if you want karaoke-style echo. If in doubt, select from the presets.
3. Check the OUT meter to see if the bar stays within the target zone while singing. If it does not reach the zone, adjust the mic input gain (via your computer sound settings or audio interface knob). The volume fader in the OBS mixer is applied after the plugin, so it does not affect the meter here.

* Default knob values: SHINE 40, SPACE 30, ECHO 20.

7. Tips

• Combine with VELVOX: If you also want to shape your speaking voice, combine VELCANTO with VELVOX. In OBS, the recommended filter order is: OBS built-in noise suppression → VELVOX → VELCANTO. When using together with VELVOX, keep SHINE moderate.
• Noise reduction: If background noise is a concern, combine with Tonecraft Tokyo's AI noise suppression plugin SILENTIQ (trial version) or OBS built-in noise suppression.
• Using in a DAW: In a DAW, insert VELCANTO as a standard effect on your vocal track.

8. About VELCANTO Pro

For users who need more advanced capabilities, the upgraded edition "VELCANTO Pro" (500 JPY) is available. VELCANTO Pro adds the following features:

• TUNE panel PITCH "Tunes notes": Pulls off-pitch notes toward the nearest notes. Tuning 40 sounds natural; higher values pull them more firmly.
• TUNE panel ROBOT button: When turned on, switches pitch transitions abruptly in steps for a robotic voice effect.
• TUNE panel Pitch needle: Indicates whether the voice reaching the listener is lower or higher than the nearest note, centering as PITCH is turned up.
• TUNE panel KEY & AUTO: Restricts target notes to the notes of the song. With AUTO "Listen", singing about one chorus allows VELCANTO to listen to the notes used in the song and select the KEY automatically.
• SING "Vocal" button: Turn off to return to your natural voice for talking between songs, while acoustic space and echo ring out naturally.
• Presets & User presets: Adds Pro presets (P01 STEADY VOICE, P02 PITCH ASSIST) and allows saving, deleting, exporting, and importing user presets (.velcanto files).
