I have just released pianoscope v2.0 to the App Store. Check it out while it's still fresh. These are its release notes:
Our new algorithm v2 for calculating tuning curves produces improved results for many instruments, providing better stretch in the bass and purer twelfths in the treble (depending on the chosen tuning style). Existing tuning documents will continue to use the old algorithm v1 until you explicitly switch then to use v2 in the tuning curve panel (pro version) or if you change the tuning style.
In the pro version, you can now record an existing tuning as a Static Tuning in addition to using styles. They are an excellent way to save and restore aural tunings. To create a new static tuning, simply press the plus button in the tuning curve panel. After measuring, the new static tuning will appear in a separate section below the tuning styles and can be selected in the same way. Static tunings are specific to each instrument and are therefore stored within individual tuning documents. You can also use them to copy an aural tuning from one instrument to another, such as for piano duets. Keep in mind that applying a static tuning to an instrument of a different size or inharmonicity may cause the tuning indicator to be less stable as pianoscope uses multiple partials to determine the pitch.
pianoscope now also has a new menu button in the instrument settings for the concert pitch, featuring the options Measure and Optimize. Measure allows you to play an A4 and adopt its current pitch, while Optimize determines an optimal concert pitch for an instrument based on its current tuning state that requires a minimum of pitch changes. This function has three different uses:
1) If you are setting up a new document and have not yet measured the inharmonicity, Optimize will open the inharmonicity panel and guide you through the measurement process before automatically adjusting the concert pitch.
2) If you have already measured the inharmonicity, you will be given the option to use the recent values.
3) If your document contains an older measurement, a panel will guide you through sampling a few notes before automatically adjusting the concert pitch.
pianoscope can now also generate tones through the built-in speaker or headphones. These tones can be used to quickly chip-tune an instrument after restringing or to help you train your ears to the inharmonic partial structure of a piano sound. To use this feature, simply select the Generate Tones option from the menu.
In addition to these new features, we have made a few changes to the app. The row for changing the concert pitch is now located at the bottom of the instruments settings panel to better reflect its dependence on the Tuning Style, Temperament, and Range options. The app now also better adapts to changing loudness levels. We also slightly changed the design of the tuning view to better work with the dynamic island on the new iPhone 14 Pro. Lastly, our user manual has been updated to include information on all new features and changes.
We have also fixed an issue where audio recording did not work on the new 12.9" M1 iPad Pro.
