Practice Every Part
RazielReveal
Turn songs you own into a private practice session for singing, guitar, and piano with separated stems, timed lyrics, chords, MIDI guides, Litejam, and ROLI.
For focused practice
Separate, slow down, transpose, and follow every part.
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.
Use only audio you own or have permission to use. Processing and analysis are designed for private practice, study, and preparation.
- Shape every part with independent level, pan, mute, solo, 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 with zoomable piano rolls, spectrum backgrounds, bars, beats, lyric words, and chord annotations.
- Follow word-timed lyrics and chords in Adaptive lines or Sentence lines, with the current lyric word and chord highlighted.
- Use Bar & Beat Chords, song-section markers, and segment tags to jump between parts of a song.
- Connect Litejam guitar over Bluetooth, or practise with supported ROLI Piano and LUMI Keys devices.
- Optionally unlock Premium features including audio and MIDI export, sheet auto-scroll and printing, and song-bundle backup and restore.
