- 📦Tetratonics: The 4th Dimension version 2.1.1WELCOME TO THE FOURTH DIMENSION: TETRATONICS 2.0 IS LIVE!
What was once a silent visual calculator is now a high-fidelity, playable, tactile instrument. Version 2.0 transforms Tetratonics into a professional, zero-latency harmonic laboratory. We have rebuilt the entire app from the ground up around a dual-sampler AVAudioEngine to let you play, layer, and orchestrate modern jazz harmony in real time.
Here is the complete, high-fidelity breakdown of everything new in Version 2.0:
--- THE SOUND STUDIO ---
Step into a glassmorphic control room. Rebuilt as a unified three-tab panel, the Sound Studio lets you sculpt every detail of how your harmony is arranged and performed:
- TETRATONIC TAB (Melody): Sculpt the upper structures. Drag-and-drop to reorder scale pitches into custom licks, apply 7 geometric arpeggio patterns (Ascending, Descending, Pendulum, Arc, Resolve Up, Resolve Down, Block), and slide note timing from driving to loose.
- CHORD TAB (Harmony): Voiced with 8 gorgeous pads. Select from 6 classic voicings, 3 articulation styles, and 4 velocity contours visualized as live sparklines.
- MIX TAB: Independently balance the volume of the chord and tetratonic layers from 0% to 100% of your device's full dynamic range.
--- 17 CURATED, CALIBRATED INSTRUMENTS ---
No more flat, dry synthesizer tones. Tetratonics 2.0 features 17 studio-grade, gain-staged instruments divided across two independent layers:
- 8 CHORD TIMBRES: Rhodes (vintage warmth), Strings (orchestral swell), Synth Pad (ethereal stereo), Vibraphone (metallic bell), Guitar (acoustic pluck), Grand Piano (acoustic benchmark), Perc Organ (classic organ click), and Warm Pad (analog sweep).
- 9 MELODIC TIMBRES: Celesta (crystalline attack), Marimba (wooden resonance), Flute (woodwind breeze), Music Box (delicate chime), E. Piano (percussive bite), Harp (sweeping classical pluck), Clavinet (funk-infused bite), Vocal Lead (wordless swell), and Square Lead (digital retro).
- PRO LOUDNESS PARITY: Every instrument is individually calibrated across three axes (velocity, sampler gain, and output dynamic ceiling). You can switch from a punchy Clavinet to a breathy Flute with zero perceived volume jumps.
--- JAZZ VOICINGS & SHIELDED ENHARMONICS ---
Our Harmonic Intelligence engine actively listens to your choices, dynamically restructuring the accompaniment to support your scale:
- 6 PROFESSIONAL VOICINGS: Stack them closely in Root Position, spread them using Open Position I (Drop 2) and Open Position II (Drop 3), frame them with Root + 7th (Shell), anchor the bass with Root Only, or play our bespoke "Tetratonic" voicing, which seamlessly fuses the chord's core skeleton with your scale notes voiced as a cohesive upper structure.
- THE THEORY DONE FOR YOU: Drop any four-note scale over any chord and watch our engine resolve enharmonic ambiguities (knowing b5 vs #11, b13 vs #5). The scale builder respects key signature gravity (flat roots use flats; sharp roots use sharps) to present flawlessly spelled chord symbols like Cmaj7(9/#11) and G7(alt).
--- THE INTERACTIVE HARMONIC DIAMOND ---
Our 12-tone chromatic visualizer is now a fully interactive instrument. Notes are color-coded by chord function: Core Tones (blue), Guide Tones (green), Extensions (amber), and Altered Tensions (crimson). Tap any note on the outer ring for an instant, haptic-synced audio preview, or tap the center to trigger the full, combined performance.
--- STAGE-READY PRO-AUDIO RESILIENCE ---
Built for the gigging musician:
- ADAPTIVE INTERFACE: Seamlessly rotates between portrait pocket reference and landscape practice layout.
- LIQUID GLASS DARK MODE: Sleek, high-contrast aesthetic designed for lit stages.
- AUDIO RESILIENCE: Gracefully survives phone calls, backgrounding, notification alerts, and hardware changes (AirPods unplugs, Bluetooth device switches) without clicks or dropouts.
- STRICTLY OFFLINE: Zero ads, zero subscriptions, zero tracking.… more - 🆕Tetratonics: The 4th Dimension released on the App Store

About Tetratonics: The 4th Dimension
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.
