Tetratonics - The 4th Dimension Four Notes. Infinite color. Step into the 4th dimension of modern jazz harmony. Tetratonics reveals the secret behind modern jazz voicings: take a major or minor triad you already know, add one carefully chosen color tone, and superimpose the resulting 4-note tetratonic structure over any chord. The result is immediate - beautiful, sophisticated harmony within reach. The ultimate harmonic laboratory for improvisers, composers, and arrangers, bridging the gap between abstract theory and concrete sound. --- THE CORE SYSTEM: 10 CURATED STRUCTURES Tetratonics curates the 10 highest-value "Triad + 1" combinations used in contemporary jazz: - 6 Major-Based: (b2), (2), (#2), (4), (#4), (b6) - 4 Minor-Based: -(b2), -(2), -(4), -(#4) Optimized for harmonic beauty and functionality, every combination sounds incredible. --- THE SOUND STUDIO [NEW IN 2.0] Tetratonics is no longer just a visualizer - it's a premium, high-fidelity auditioning space. Rebuilt on a zero-latency audio engine, our glassmorphic Sound Studio lets you play and mix voicings across two independent layers. Assign 17 gain-staged instruments (8 chord pads, 9 melodic leads) with perfect perceived-loudness parity - no volume adjustments needed when switching timbres. --- CONTEXT-AWARE AUDIO ENGINE [NEW IN 2.0] Our Harmonic Intelligence engine dynamically adapts underlying chord voicings to match your chosen scale perfectly. - 6 Voicings: Root Position, Open I (Drop 2), Open II (Drop 3), Tetratonic (upper structures), Shell (Root + 7th), or Root Only. - Articulation: Select Strum Up, Strum Down, or Block. Adjust strum speed, note spacing (Loose-to-Tight), and choose from 4 velocity contours (Flat, Rise, Fall, Accent Root). - Custom Sequencer: Drag-and-drop to reorder scale pitches into custom melodic licks, or apply 7 geometric arpeggio patterns like "Arc" or "Pendulum." --- THE HARMONIC VISUALIZER Our stunning visualizer maps exactly how your chosen tetratonic structure relates to your underlying chord on a 12-tone chromatic ring: - See the tetratonic pitches form a unique geometric shape reflecting precise intervallic relationships. - Notes are color-coded by harmonic function: Core Tones (blue), Sevenths (green), Natural Extensions (amber), and Altered Tensions (crimson). - Tap any note for an instant preview, or pivot your starting point with a tap. --- FLAWLESS ENHARMONIC CALCULATION Drop a Triad + 1 structure over any chord and our analytical engine decodes the result. The app distinguishes between complex contextual choices (knowing when an interval functions as a b5 vs a #11, or b13 vs a #5) and outputs the perfect, standard-compliant jazz chord symbol (e.g., Cmaj7(9/#11), G7(alt)). The intelligent scale builder respects the enharmonic gravity of your chord - over flat roots, you see flats; over sharp roots, you see sharps. Every pitch is spelled correctly. --- THE CONTROL ISLAND & FAVORITES A tactile interface designed for quick adjustments. Rapidly switch between the 10 master archetypes and see your tetratonic formula. When you stumble upon a killer voicing, tap the star icon to save it, and instantly preview or audition it directly from your Favorites library with a single tap. --- DESIGNED FOR MUSICIANS, BY MUSICIANS Built to feel like a high-end piece of gear: - Adaptive Layout: Shifts perfectly between portrait reference and landscape practice modes. - Premium Dark Mode: A "liquid glass" aesthetic that preserves your vision on lit stages. - Haptic Touch: Tuned tactile haptics sync perfectly with note triggers to make the screen feel like a physical instrument. - Pro-Audio Resilience: Rebuilt on a robust signal chain that gracefully handles interruptions (calls, Siri) and headphone changes without dropping a beat. - Strictly Offline: Zero ads, zero subscriptions, zero data collection. Runs entirely locally on your device. Discover a lifetime of modern harmonic color with Tetratonics today.

Ohms Sample turns an audio file into playable slices and a grain cloud. Drop in a loop, move its transient slices, and play on screen, from Mac keys, MIDI or a Launchpad. A starter drum loop is ready on first launch; sound starts only when you play. SLICE AND SHAPE * Up to 16 slices with tune, volume, pan, attack, release, reverse, looping and choke groups. * Tap slices, hold a two-finger grain loop, scrub like tape, or play one slice chromatically. * Zoom the waveform, cut or keep a range, reverse it, or stretch it from 50% to 200% without changing pitch. Restore the original source. * Master tuning includes a one-tap A = 432 Hz. TWO SOUNDS, ONE GRAIN CLOUD โ€” STANDALONE * Shape up to 128 grain voices with position, size, density, pitch and spread. * Choose relative scale intervals, interval shift, pitch scatter and reverse chance. Off leaves pitch unsnapped; sources are not automatically key-detected. * Add Source B from a file. B chance chooses A or B for each new grain. Pads keep Source A. * Separate trims attenuate each source. Tune B manually in one-cent steps. Replacing A rebuilds B at A's rate. * Undo grain settings or a source change. Missing-file references stay until you relink or remove them. LET THE SLICES PLAY * Pattern presets, weighted Orbit routes and Weave, Pulse, Interlock and Drift paths. * A 1โ€“64 step Pulse lane, Chance controls, per-slice gestures, a 3ร—4 snapshot bank and four trigger pads. * Catch the last 1, 2, 4 or 8 bars of slice events as a Take, then export WAV or MIDI. Use Record mix to capture the grain cloud itself. KEEP YOUR WORK * Record mix in Grain or Record Output in Take keeps up to 60 seconds of stereo output with pads, grains, filter, delay and reverb. * Recordings wait for Use Recording or Keep Current. Using an effected mix switches inserts off so they are not applied twice. * Microphone recording is in Take. On Mac, optional Sample Anything holds the last 60 seconds of system audio after you enable it; no screen frames are stored. * Export WAV, save sessions, or keep up to 256 reusable recipes. Recipes contain settings, never audio or source bookmarks. * Sessions open stopped. New-feature documents require this version; original settings remain readable by earlier releases. New committed edits stay in local app storage for session reopening. KEYS, MIDI AND AUv3 * Mac Aโ€“P keys, MIDI slice and trigger notes, learned CC controls, MIDI clock and dedicated Launchpad Mini MK3, X and Pro MK3 pages. * The AUv3 instrument plays slices, loom paths and insert effects with 24 automatable parameters and host-saved state. It preserves grain settings in recipes, but does not load Source B or render the standalone grain cloud. Audio stays on your device. No account, analytics, advertising or cloud audio processing. One purchase covers macOS 14 or later and iPadOS 17 or later, with no subscription or in-app purchase.
