A tiny solar system that plays piano. Four orbs, a gravity well, and walls that ring like bells. Fling an orb and it falls, ricochets, and plays notes. Where it hits a wall decides what it plays; the physics decide when. You don't write the music. You build a small world and curate what it sings. Gravity is a touch instrument first. Grab an orb and it follows your finger; let go and the throw becomes its velocity. Drag the gravity well and every orbit in the room bends. Set Pulse and the well breathes in time with the tempo, so chaos starts keeping a schedule. EVERYTHING LANDS IN KEY Every impact point along the boundary maps to a note of the current scale, low at one end, high at the other. Pick from 16 scales and 11 tuning systems (12-TET, just intonation, maqam, shruti and more). The scale strip along the bottom is a key-change timeline: tap a segment, change the key, and the whole world modulates on the bar. EIGHT WORLDS TO BOUNCE IN Rectangle, circle, triangle, hexagon, pentagon, octagon, diamond, star. Sharp corners ricochet hard and play jagged. Round shapes glide and play smooth. SOUND A 16-voice pluck engine through a double-bass body and reverb. Octave, key range, quantize from 1/32 to 1/2, orb-to-orb collisions on or off. Presets to start from, themes for the visuals. AUv3 AND STANDALONE Use Gravity full-screen as a standalone instrument, or load it as an AUv3 in GarageBand, AUM, Logic Pro, Cubasis, Loopy Pro and any other Audio Unit host. Each orb has its own MIDI channel, so Gravity can drive other instruments in your host. ONE PRICE No account, no ads, no in-app purchases, no data collected. Buy it once and it's yours. The same engine ships as a VST3 and AU plugin for Windows and macOS at touchmachines.com.

BLEASS Spectral Reverb is an effect and sound design tool that gives you precise control over how ambience evolves across the frequency spectrum. Its intuitive Spectral Maps let you shape different frequency regions independently, creating anything from smooth, expansive spaces to fragmented and glitchy textures. Attack, Decay and Width each come with their own frequency-dependent Spectral Map, extending the core reverb far beyond conventional controls. Freeze and Kill bring instant control over evolving tails, while Block Size, Hop Factor and Smooth Size let the spectral engine move from clean and precise to rough, fragmented and characterful. Four processing slots can host any of six dedicated spectral effects: Spectral Gate, Harmony Follow, Spectral Ducker, Spectral Enhancer, Pitch Shifter and Frequency Shifter. Shape, enhance, duck or shift selected parts of the spectrum, with external sidechain support for even more responsive processing. Explore spacious, polished, abrupt, fragmented and harmonic reverbs with the depth and immediacy of BLEASS Spectral Reverb. BLEASS Spectral Reverb is available as an AUv3 plugin or a standalone app. BLEASS Spectral Reverb is also available on Windows, macOS, and Linux.
