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.

About

Tāl Chakra

Read full description

Your guru draws a circle on the board, marks the beats, claps the vibhags, and suddenly the taal makes sense. Tāl Chakra puts that moment in your pocket. This is not a tabla machine. It is an interactive guide to the rhythmic architecture of Hindustani classical music. Each taal is drawn as a circle (the way musicians have understood rhythm for centuries) and brought to life with real tabla recordings, animated playback, and tools that let you take the structure apart and put it back together. 16 TĀLS, ONE CIRCLE From the 6-beat Dādrā to the 16-beat Tīntāl and the rare 14-beat Ārā Chautāl, each taal plays with studio-recorded tabla samples across three dynamic layers. Watch the bead travel the cycle, hear each bol as it lands, and build an intuitive sense of the rhythm that no metronome click can give you. X-RAY MODE Peel back the layers of any taal. Concentric rings reveal vibhāg groupings, tālī and khālī accents, and mātrā positions side by side. See instantly why Rūpak feels nothing like Jhaptāl, even though they are only one beat apart. Compare two tāls with the same beat count by crossfading between them. LAYKĀRĪ LAB Practice subdivisions against a running cycle. Choose from nine ratios: from barābar (1:1) up through sātgun (7:1), plus the fractional cross-rhythms kuāḍ and āḍ. Colour-coded chips group the ratios into three families. Tap Auto and the app cycles through whichever family your current ratio belongs to, advancing one step per full taal cycle, the way your guru would push your speed in a lesson. Watch the subdivision dots appear between the beats and hear a second layer play against the taal. TIHĀĪ BUILDER Compose three-phrase cadences that resolve on sam. Set the starting beat, phrase length, and gap, then watch three coloured arcs draw themselves around the circle in real time. Green means it lands. Red means it doesn't. Tap play to hear your tihāī against the running taal, and feel the resolution when the third phrase hits sam. Includes 48 classic preset patterns across the tāl library, tailored to each rhythmic cycle. TEMPO LAB AND PERFORMANCE MAP Explore the relationship between tempo and density across five laya zones, from Ati Vilambit to Ati Drut. Then zoom out with the Performance Map to see how rhythm lives inside a full rāg performance: from the unmeasured ālāp, through the gathering intensity of the gat sections, to the climactic final cadence. BUILT FOR SERIOUS PRACTICE A tanpura drone in all 12 keys gives your practice a tonal anchor. Haptic pulses mark sam or every beat, so you can close your eyes and still feel the cycle. A session counter tracks completed cycles and elapsed time. A glossary of 50+ terms with Devanāgarī script helps you learn the vocabulary alongside the music. Designed for iPhone, iPad, and Mac.
