Montal Tuner1.8 - App Store

Montal Tuner is 100% designed from the ground up for blind piano tuners to provide an electronic tuning aid similar to the professional visual piano tuning aids. It provides a unique feedback sound that conveys the same sense of movement that is provided by strobe-type displays to indicate sharp or flat. Samples of these sounds can be previewed on our support website, along with the complete user manual that is included in the app as help files. This app should be used with VoiceOver turned on and with headphones connected.

Notable features of Montal Tuner:

* Measures and uses inharmonicity of the piano to construct a custom tuning for each piano.
* Can store and recall tuning files for individual pianos
* Includes a pre-packed tuning file for an average piano if you don't want to create custom tunings.
* Can be set up to use historical unequal temperaments.
* Switches notes automatically when you play the next note.
* Pitch-raise mode included.

Montal Tuner lets you customize a tuning by sampling the inharmonicity for a few notes of the particular piano. You can choose the kind of tuning stretch you want, based on octaves, double-octaves, or other intervals. Then you start tuning.

After a custom tuning has been created from inharmonicity measurements, you can store this tuning by name. The next time you need to tune that piano, or one very much like it, you simply load that same tuning file and start tuning. There essentially is no limit to the number of tuning files that you can save. Montal Tuner comes with an "average" tuning file so you can start tuning right away.

Montal Tuner covers the normal piano range from A0 to C8 (88 notes). The automatic note-switching feature makes it possible to enjoy hands-free operation. Montal Tuner switches up to 3 notes up or down from the current note. In addition to automatic note-switching, there is also one-touch manual note switching.

The sweeping tone tuning indicator used by Montal Tuner to simulate a strobe tuner is filtered white noise rather than a pure tone. This allows the user to hear the piano directly while the sweeping tone is sounding. The goal in tuning is to stop the sweeping of the tone - just like stopping the movement of a visual strobe.

The pitch-raise function pre-measures the pitch of the piano before you tune it. Based on these measurements, tuning targets are established a calculated amount beyond the desired pitch for each note. After all the notes have been tuned in this way, the pitch of each note is closer to the desired pitch than if these exaggerated tuning targets had not been used.

Version History * Over-pull mode now includes compensation for the treble strut locations.
* Several optional levels of filtering of the response to tuning error allows the user to balance response time and smoothness of the sweeping tone.
* Internet Calibration now offers an early termination option.

* Fixed the interval selection page so that VoiceOver says which picker is being accessed - the Bass interval, the Mid interval, or the Treble interval.

* A one-time announcement on how to find out what's new plays 6 seconds after the program starts on the tuning page. Also the information on what's new is always available by a new button on the "About Montal Tuner" page in settings. 1.8 08/14/2025 1. Bug fix: When loading a tuning file the redundant VoiceOver reporting of the number of files in the list on every entry has been eliminated. Now the number of items in the list is only announced when you first open the list of tuning files.
2. An added option mutes the sweeping tone when you are trying to tune unisons aurally.
3. When the pitch of the note being tuned is more than 40 cents off from the correct pitch, VoiceOver announces the amount of tuning error numerically.
3. An added option generates the target pitch instead of the sweeping sound whenever the note being tuned is very far from the correct pitch.
4. Default partials for new tunings can now be set to custom values to override the standard default table of partials. Also the default table of partials for new tunings has been changed to use the fourth partial in the low bass. 1.7 11/27/2022 More robust handling of phone call interruptions.
Ability to send audio to a connected bluetooth headset or EarPods when used with iOS 10 and above. 1.6 10/29/2021 An option has been added to force the use of the built-in microphone instead of the microphone in the headphones when headphones are connected that also contain a microphone. 1.5 04/23/2021 Audio configuration is revised to use the louder speaker or headphone output instead of the quieter phone receiver output.
The 3-part tuning option is available when creating a new custom tuning for between control over stretch in the mid-range.
Measurement of inharmonicity is clarified with Voice-Over announcements.
Auto-all auto note switch option has been added.
Two-fingered Z-gesture can be used to skip notes in pitch-raise remeasuring and to cancel an inharmonicity measurement before it completes. 1.4 07/31/2020 1. Provisions added for historical unequal temperaments.
2. Offset adjust VoiceOver guidance option added. 1.3 11/02/2018 iOS 9 compatibility issue fixed. 1.2 11/09/2015 A Pitch-raise mode is added for tuning a piano that is very flat.
Time-saving accessibility "escape" Z-gestures are added to most screens.
Measurement of inharmonicity has been streamlined for easier use.
Stored tuning files are more easily searchable. 1.1 09/02/2015 1.0 04/17/2014
