PIATUNE PROFESSIONAL PIANO TUNING APPLICATION

Features

Aural like tuning procedure

PiaTune uses an F3 - A4 temperament. Just like an aural tuner would do, first four contiguous M3rds are established between F3 and A4. Then the width of the fourths are optimized to get an even progression on major thirds, fourths and major sixths. Result is a perfect equal temperament.

The bass and treble is expanded from this temperament just like an aural tuner would do. PiaTune listens to the note and calculates the frequency that would satisfy the interval widths with the previously tuned notes.

Actual beat rates of major third, sixth and tenth intervals related to the temperament can be measured. Intervals range from G#2 to F4. The beat rates of fourths, fifths and 4:2 octaves within the temperament can be calculated using the measured values.

Save Your Tunings

The first time you tune a piano the above described procedure is used. When you finish the tuning (or during the tuning) you can save the data. The next time you tune the same piano, it is as easy to load the previously saved file and tune the piano. This time, since all the targets are already calculated, you can tune the piano in any order you want. Even if you change the octave sizes, there is no limitation or pattern, because the calculations are done on the fly.

Set A4 to a non-standard frequency

You can set A4 frequency to a value other than the standard pitch of 440 Hz. The frequency can be set between 392.00 Hz and 466.99 Hz with 0.01 Hz steps.

Automatic note change

When the setting of the temperament is finished or you tune a previously tuned piano by loading the saved tuning file it is possible to change notes automatically. When AutoNote feature is active, if the note you played is in the range of plus/minus three semitones from the current note, PiaTune automatically switches to that note.

Choose your Stretch and Temperament

Stretch:

Depending on the size and scale of the piano you can choose different stretches. For the temperament octave and midrange you can choose a 4:2 octave or a compromise between a 4:2 octave and 6:3 octave. For the bass, 6:3, 8:4 and 10:5 octave sizes are available. For the treble a 4:1 size might be suitable for most pianos. But in case you prefer the last octave to be single octaves you can choose 2:1. 

There is also a special stretch for small pianos like spinets which will tune the bass section all 6:3 octaves.

Temperament:

Besides the default Equal Temperament, PiaTune comes loaded with a select number of unequal temperaments. The provided temperaments are, 1/4 Meantone, Kirnberger-III, Valotti, Werckmeister-III and Young. You can add other unequal temperaments though the Temperament screen. Just enter the cent offsets of your temperament with A at zero offset. Also it is possible to transpose the temperament to other notes than the default note C.

Over pull

When you activate the Overpull feature, the note frequency is briefly measured and an over pull value is calculated based on the over pull percentages you have set and the note being tuned. There are three over pull percentages that can be set, bass, midrange and treble.
