Ivory Pro: Piano Tuner Pro

Sub-cent piano tuner with custom profiles, stretch tuning, historic temperaments, strobe visualizer, pitch raise wizard, tuning history, and a polyrhythmic metronome.

IVORY PRO - The Professional-Grade Piano Tuner for the Apple Ecosystem

Engineered for Ultimate Acoustic Precision Ivory Pro is a masterclass tuning suite for piano technicians and professional musicians. Leveraging a custom hybrid DSP engine, Ivory Pro delivers sub-cent frequency accuracy across the complete 88-key piano range (A0 to C8). Experience the power of professional bench-tuning equipment on your iPhone, iPad, or Mac.

Specialized Piano Profiles Built-in physical models optimized for specific architectures: • Concert Grand: Smooth, highly-damped response for slow-decaying strings. • Upright: Balanced physics for shorter strings. • Electric Piano: Lightning-fast detection for Rhodes/Wurlitzer tines. • Spinet: High-damping for highly-inharmonic configurations. • Custom Mode: Fully adjust DSP smoothing, needle response, damping, and noise gates.

Client & Profile Manager Organize your work with an integrated database. Save custom profiles for specific clients and instruments. Profiles store names, notes, A4 references, DSP settings, and historic temperaments—restoring the exact environment per client.

Inharmonicity-Aware Stretch Tuning Pianos cannot be tuned to perfect equal temperament due to string stiffness. Ivory Pro integrates a real-time Railsback stretch tuning engine. Use the Inharmonicity Profile Wizard to measure the actual string physics of your piano, generating a custom, mathematically perfect stretch curve based on professional octave-harmonic matching (6:3, 4:2, 2:1 rules).

Smart Pitch Raise & Tuning History The built-in Pitch Raise Wizard automatically calculates tension deficits to generate a perfectly tailored overpull profile. Document your work with complete Tuning History snapshots, graphing pitch drift over time to track long-term structural stability.

Historic Temperaments Explore historic temperaments with mathematically precise offsets for Werckmeister III, Kirnberger III, and Meantone (1/4 Comma).

Professional Visualizers • Strobe Tuning: The ultimate standard for precision. A dynamic, multi-band concentric strobe ring visually rotates based on phase offset, providing sub-cent accuracy at a glance. • Harmonic Spectrum Analyzer: A 60fps FFT plot renders the live spectrum of your strings, letting you visually spot false beats and analyze overtone strength.

State-of-the-Art Hybrid DSP Engine • Low-End Power: Custom sub-harmonic filters track bottom keys (A0–B0) without octave errors. • Treble Brilliance: High-resolution FFT and parabolic interpolation guarantee sub-cent tracking on the top octave. • Advanced Thresholds: Customize Treble Sensitivity and Bass Inharmonicity Tolerance.

USB & External Microphone Support • Plug-and-play detection for any class-compliant USB audio interface. • Live display of device name, sample rate, and channels. • Automatic software gain boost and multi-channel downmix.

Premium Mechanical Metronome • Real-time physical pendulum swing animation. • High-fidelity wooden, electronic, and pitched click sounds. • Support for complex time signatures, tap-tempo, and live polyrhythms. • Build Setlists for seamless transitions during gigs or practice.

"Midnight Onyx" Interface • Designed for dark concert halls and piano interiors. • Vibrant glassmorphic controls with responsive needle physics. • Tactile haptic feedback lets you "feel" perfect pitch.

Universal & Offline Privacy • Universal Purchase: Buy once, unlock full features across Mac, iPhone, and iPad. • 100% Privacy: No data collection, zero tracking. All DSP processing happens locally.
