RazielReveal vs Gravity & Wind

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. Terms of Use (EULA): https://bwinnovationtw.github.io/apps/razielreveal/eula.html

Gravity & Wind is a physics-driven generative MIDI sequencer and performance controller for iPhone and iPad. Build evolving sequences with Timed generation, hold an exact population with Fixed mode, or tap the field to perform directly. Shape gravity, directional dual-noise wind, bounce, and velocity response, then turn floor impacts into quantized MIDI notes. Free features include five scales (Major, Natural Minor, Major Pentatonic, Minor Pentatonic and Chromatic), 12 factory scenes, motion control, all generation modes, basic CoreMIDI Note/Velocity output, output channels, Bluetooth MIDI, manual sustain-pedal forwarding and up to five user scenes. Presets play with their saved scales, MIDI/Auto pitch, CC and sustain settings even in the free version. You can turn advanced settings off, edit basic parameters, and save within the five-scene limit. Enabling or changing advanced modes requires Pro; reloading a preset restores its settings. MIDI Learn/mappings and MIDI ball triggers remain Pro features. A single, permanent Pro in-app purchase unlocks choosing all 24 scales, enabling and editing advanced preset modes, and the MIDI Processor AUv3 with host sync, automation and project recall; MIDI chord pitch control and Channel 2 ball triggers; MIDI Learn; scene-energy CC 1, Wind CC 2, Direction CC 3; Held and chord-aware Automatic Sustain; and unlimited user scenes shared with the AU. No subscription. Eligible customers who purchased the app before the switch receive Pro automatically. Gravity & Wind has no built-in sound source. Route its MIDI to a software instrument, hardware synthesizer, or DAW. No separate account registration, advertising, or third-party analytics. Purchases and restoration use your Apple Account through the App Store.
