TuneLab Piano Tuner

August 16, 2024

1. Fixed a bug that can cause over-pull premeasuring to skip ahead and get out of sync with what notes you are playing. 2. Due to recurring problems with the new "auto-all" mode in automatic note switching, the automatic note switching code from version 4.6.1 replaced the new code.

Fixed a bug so that prevented auto note switching from taking the offset into account. In addition there are these changes from version 4.7: * Adjustable update rate for the Spectrum Display - up to 10 updates per second. * More reliable and sensitive Auto-All automatic note switching. * Option to auto-note switch only on the attack portion of the sound rather than the sustain portion to reduce instances of switching to the wrong note. * Phase Display speed is now a logarithmic function of the tuning error rather than linear. This gives more resolution very near to the tuning target plus more range when far from the tuning target. * Faster and more precise Inharmonicity measurements (3 seconds max instead of 6 seconds max). * Accuracy and speed of the Locking operation is improved. * Removal of obsolete creation of "split-scale" tunings. Loading of previously saved "split-scale" tunings is still supported. * Removal of obsolete manual adjustment of non 3-part tuning curves. Use 3-part tuning instead.

In addition to support for system-wide Dark Mode, this update provides an option to override the system setting for Dark Mode within TuneLab. The user may now choose to have Light Mode, Dark Mode, or to follow the device's light/dark setting.

* Responds to system selection of Dark Mode. * Displays current tuning curve interval selection on the main tuning screen. * The main tuning screen warns of a no-stretch tuning until some inharmonicity measurements are taken.

This update fixes two bugs: 1. If a new tuning is not saved and the app has to be closed for some reason, the new tuning is not restored when the app is started up again. This is now fixed so that the new tuning is restored, even if it was not saved. 2. A phone call interruption during tuning causes an audio error message that requires exiting the app and opening it again. This is also fixed so that the normal operation of the app resumes when the phone call is done.

April 18, 2021

* Better positioning of the search bar when finding a tuning file to load. * Expanded the Deviation Curve interval selections to include all intervals that are available in 3-part tuning. * Updated the Dropbox functions to use the new authorization function required by Dropbox by Sept. 30, 2021. * Provided means to save the pre-measurements from a pitch-raise by e-mailing them to the address of your choice. * Option to e-mail any tuning file or exam report to any address.

December 23, 2019

* A new tuning curve generation method called "3-part tuning" provides the means to specify the kind of interval that should be beatless at three separate places in the scale: bass, treble, and middle. * "Auto-all" note switching mode will now switch automatically from any note to any other note.

Fast one-touch access to over-pull (pitch-raise) settings from main tuning page. 4. Optional use of plate strut locations to improve pitch-raising accuracy. 5. Fixed two-fingered reset of offset in iOS 10. 6. Dropbox functions revised to accommodate changes at dropbox.com which will make the version 4.2 Dropbox functions cease to function starting in June, 2018. 7. Streamlined handling of saving tuning before starting a new tuning.
