Gravity & Wind vs RocketVerb

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.

RocketVerb is a creative algorithmic reverb for iPhone and iPad, designed to transform instruments, vocals and recordings into spaces that move, bloom and evolve. Its character was shaped through the study of public space audio, planetary recordings and astronomical data sonifications. Their spectral movement, density and texture were translated into 38 internal profiles. RocketVerb does not replay those recordings as samples or fixed impulse responses. Every reverb tail is synthesized in real time. SHAPE YOUR SPACE Use five focused controls to build the foundation of the reverb: - Pre separates the original sound from the reverb bloom. - Density moves from open reflections to smooth clouds. - Length controls the duration of the tail. - Size changes the perceived scale of the environment. - Shape moves between tight, blooming and suspended responses. MOVE THROUGH THE GALAXY The interactive Galaxy cursor modifies distance, brightness, motion, scatter and the balance between early reflections and the tail with a single two-dimensional gesture. SIX CREATIVE EFFECTS - Radiation adds energy, mass and charged texture. - Orbit introduces stereo movement and subtle pitch drift. - Filter shapes the tonal range of the processed signal. - Granular Cloud transforms audio into layered, evolving slices. - Comet Trails creates rhythmic and atmospheric delay repetitions. - Dust introduces organic noise, texture and movement. Granular Cloud and Comet Trails include interactive 8-step patterns and can process either the direct input or the reverb signal. INFINITE FREEZE Capture the current atmosphere and keep it circulating indefinitely. Release Freeze to return smoothly to the live reverb tail. 144 FACTORY PRESETS Explore eight categories covering practical mix spaces, cinematic environments, orbital motion, granular textures, dusty planetary colors and deep ambient tails. Save your own presets directly from the app. AUv3 AND STANDALONE Use RocketVerb as an AUv3 effect in compatible hosts such as GarageBand, Logic Pro for iPad, AUM and Cubasis, or run it as a standalone app with a microphone or connected audio interface. SOURCE DISCLOSURE Some public NASA audio and sonification material was used as source material during development. This factual disclosure does not imply NASA review, approval, sponsorship, endorsement or affiliation. RocketVerb is an independent ZAK Sound product. The original recordings are not replayed by the app.
