RazielReveal

RazielReveal turns songs you own into a private, on-device practice session for singing, guitar, and piano.

Import a song and create a synchronized eight-part practice mix: lead vocal, background vocal, lead guitar, rhythm guitar, drums, bass, piano, and other instruments.

With RazielReveal, you can:

• Shape every part with independent level, pan, mute, and solo controls, synchronized waveforms, meters, seeking, and transport controls.
• Adjust playback speed and key to practise at a comfortable pace.
• Create vocal, guitar, and piano MIDI guides. Explore them in scrollable, zoomable piano rolls with a spectrum background, bars, beats, lyric words, and chord annotations.
• Follow on-device, word-timed lyrics and chords in a singer-friendly sheet. Choose Adaptive lines or Sentence lines, see the current lyric word and chord highlighted, and keep instrumental chord passages readable.
• Switch to Bar & Beat Chords for a measure-oriented view. Song-section markers and quick segment tags make it easier to jump between parts of a song.
• Connect a AUPHY GT guitar fretboard lights or Litejam Guitar over Bluetooth for illuminated fretboard guidance, or practise with ROLI PIANO / LUMI KEYS with on-screen piano roll and on-screen keyboard.
• Save songs and their local analysis for later practice.
• Optionally unlock Premium features, including audio and MIDI export, sheet auto-scroll and printing, and song-bundle backup and restore. Purchases are optional and can be restored from the paywall.
• Keep your music on your device: separation, analysis, and playback are performed locally.

Use only audio you own or have permission to use.
