About this app

Your smartphone sings!

This app plays and sings for you simply by inputting musical notes and lyrics.

It supports UTAU voicebanks, allowing you to enjoy various singing voices available online, such as Teto Kasane (*3) and Ritsu Namine (*4).

Its intuitive operation makes songwriting and composing fun.

This app is recommended for those looking for an easy-to-use app for songwriting, composing, or music education, such as:

* You want to create original songs!

* You want to include vocals, like with Vocaloid (*1) or UTAU (*2)!

* You want to play melodies you've thought of using various instruments!

* You want to check (play) and arrange melodies found in books.

* You want to check melodies you've transcribed by ear!

* While it can't create high-function, high-quality songs like Vocaloid (*1) or UTAU (*2), it's perfect for those who want to start for free on their smartphone.

*This app is a DTM (Desktop Music) software, generally known as a piano roll-style MIDI sequencer.

*You can import songs created with "Paint Music 2".

[Announcement]

From Version 2.0, you can now import vocals (UTAU sound sources).

Many sound sources for UTAU (*2) are available on the internet, and you can import them and make them sing with PaintVoice.

Please try it out.

[How to Use]

Operation is simple.

You can input and play notes with the same feel as drawing software, using a pen, eraser, copy & paste, and Undo/Redo!

To input notes, simply drag your finger to the desired location on the piano roll.

Inputting lyrics is also easy; simply enter the lyrics (pronunciation) in hiragana.

Detailed instructions are currently being prepared.

(*1) What is VOCALOID? (※Quoted from Wikipedia below)
VOCALOID is a general term for voice synthesis technology developed by Yamaha and its application products. The abbreviation "Vocaloid" is also used.
By inputting melodies and lyrics, it can synthesize singing voices based on sampled human voices.
Regarding compatible sound sources, various companies that have licensed Yamaha primarily produce their own singer libraries containing sampled voices, which are then combined with Yamaha's software and sold as products.
"VOCALOID" and "Vocaloid" are registered trademarks of Yamaha Corporation.

(*2) What is UTAU? (※Quoted from Wikipedia below)
UTAU is singing voice synthesis software for Windows and Mac OS, distributed as freeware by Ameya/Ayame.
