Stochastic Lab vs RocketVerb

Stochastic Lab is a generative composition tool built around the mathematical methods Iannis Xenakis used to compose: probability distributions, stochastic processes, and Markov chains, applied directly to sound. GENERATE • 6 generation modes: melody, rhythm, cluster, cloud, pointillistic, sequence • 6 probability distributions: uniform, Gaussian, exponential, Cauchy, Poisson, linear decay • Full control over density, register, tempo, block length, and Markov-driven contour • Choose a single orchestral section (strings, winds, brass) or let the generator blend all three • Pick exactly which percussion sounds are in play REAL INSTRUMENTS • Real sampled strings (high & low), winds, brass, and an 8-piece percussion kit — not synthesized approximations • Authentic short (pizzicato/staccato) and sustained articulations • Genuine glissando and tremolo, generated as part of the composition itself EDIT & PERFORM • Full piano roll editor: drag notes, edit pitch by semitone, adjust duration and velocity • A live recording keyboard to play your own material into any layer • Freeze a generated block into a fixed, fully editable sequence at any time SCORE • A live, Xenakis-style graphic score (particle-cloud visualization) for every layer • Expand any layer — or the full combined score — to fullscreen, with zoom and a moving playhead • Export the score itself as a printable, shareable image SEQUENCE & ARRANGE • Multi-layer Sequencer for building full compositions from generated or recorded material • Song mode for arranging multiple sections into a complete piece EXPORT • Export audio (WAV) and MIDI, mixed or as separate stems per layer, straight from the Generator, Sequencer, or Song view AUv3 PLUGIN • Stochastic Lab also runs as a real Audio Unit (AUv3) instrument inside GarageBand, Logic, AUM, and other hosts • The actual generative engine runs live inside your DAW — not a static sample player • A dedicated on-plugin control panel (mode, distribution, density, pitch range, tempo, and more), with a Preview button to audition before recording • Full MIDI recording support, including pitch bend and glissando THEORY • A built-in Theory section covering Xenakis's life and stochastic music concepts, with real-instrument audio examples for every distribution Stochastic Lab works entirely on-device — no account, no internet connection required, no data collected.

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.
