The "Piano Tuner" application allows you to tune your piano to perfection—quickly and easily—while providing complete control over both tuning and voicing. You can choose from a variety of temperaments, which are simple to configure.

"Piano Tuner" was developed entirely by a piano technician who is also an experienced software engineer. Originally created for personal use, it is now available to all piano enthusiasts.

"Piano Tuner" features a physical-modeling audio engine that generates the authentic sound of the specific piano being tuned, based on an analysis and recording of its physical characteristics. This enables you to test temperaments and tuning adjustments before applying them, and even allows you to play the instrument using a MIDI keyboard.

"Piano Tuner" app is the most advanced toolset for piano tuners, piano technicians, piano rebuilders and manufacturers of any instrument.
The first physical modeling MIDI/MPE synthesizer available on Android for musicians, and it is arguably the most powerful and open in its desktop version; it is not limited to the piano, it can mimic almost any instrument and comes with a timbre capture and real-instrument modeling tool.

"Piano tuner" and any musical instrument tuning device (ETD), Acoustic Lab for spectral sound analysis and inharmonicity measurement, MIDI/MPE Synthesizer via Physical Modeling.
A high-precision toolset for piano tuners, piano and instrument makers, musicians, as well as for acoustics research and education.

The MIDI-controlled Audio Synthesizer allows musicians to play or design virtual instruments, and enables piano tuners to hear the results of a selected temperament before tuning the actual instrument. Furthermore, thanks to flawless physical model synthesis, tuners can tune by ear, ensuring that all partials of a synthesized note are perfectly in phase with the partials of the real piano.

It integrates the exact same synthesis engine and diagnostic/creation algorithms as the "ViGAPhone Synth Lab" desktop suite, tailored into a mobile format optimized for field use.

The application meets the high standards of two complementary profiles:

• For Piano Tuners and Technicians: Advanced spectrum analysis allows you to visualize, measure, and faithfully reproduce the instrument's timbre in real time. It is the essential assistant tool for conducting precise acoustic diagnostics and carrying out expert voicing and tuning work.

• For Musicians and Sound Creators: This analysis module provides a scientific foundation to study existing acoustic properties or design brand-new virtual instruments, fully powered by our physical modeling synthesis engine.

How to tune a piano in 2 steps:
1 - Select piano preset, or build it by measuring its inharmonicity
2 - Use the tuning assistant
