Key features

Type lyrics and hear vocals

PaintVoice（歌声合成＆作曲アプリ） turns typed lyrics and placed notes into a singing line on your phone. You adjust timing by moving notes, then play back to confirm both melody and pronunciation. This is useful for checking phrasing before arranging the rest of the parts.

Draw melodies in a piano roll

You create and edit phrases in a piano roll with familiar tools such as pen, eraser, selection, copy and paste, plus undo and redo. Chord input is supported so you can build harmonies and thicker textures. For timing and detail, you can set tempo between 30 and 240 BPM, use triplets, quintuplets, or sextuplets, and place very short values down to 128th notes.

Arrange with multiple tracks

PaintVoice（歌声合成＆作曲アプリ） provides four vocal tracks and sixteen instrument tracks for building full ideas. You can choose from 128 instrument sounds and a drum set to make backing lines, intros, and fills. As the project grows, mute and solo help you focus on sections and balance parts more easily.

Import UTAU voicebanks

From version 2.0, you can import standalone UTAU voicebanks to try different singing voices. After import, assign a voice to a vocal track and test pronunciation with short phrases. This lets you compare tone and clarity before recording a full part.

Export audio, MIDI, and lyric video

When a draft is ready, export a MIDI file, an AAC audio file, or an MP4 video with lyric captions. The lyric video format is practical for quick posts or practice because words appear in sync with notes. Sharing is straightforward once files are saved.

Before you start with PaintVoice（歌声合成＆作曲アプリ）

PaintVoice（歌声合成＆作曲アプリ） focuses on simple singing synthesis for drafting and study. It is not intended to replace high end engines such as VOCALOID or deeply tuned UTAU setups. For detailed vocal control and premium timbre, dedicated tools are better suited. For melody checks, lyric timing, and short demos, this app offers a direct workflow.

Use cases and workflow tips

Many users try it for ear copy checks, textbook melody playback, or rough sketches of original songs. You can quickly audition a chorus by entering chords and a guide vocal, then export MIDI to continue arranging in other tools. Lyric caption MP4 is also helpful for sharing short demos or practicing with on screen words.
