TUNIC only:pure Piano Tuner: Professionelle Meisterschaft mit der Stopper-Temperatur

TUNIC only:pure is a piano tuning software for both occasional and professional piano tuners or concert technicians. THE MOST SIMPLE APP AVAILABLE FOR PIANO TUNING - Piano nonlinearity (stiffness, damping) are processed automatically without the need for pre-calculating stretch curves. - The App provides outstanding unison purity not achievable with conventional tuning programs. - No special tuning sequence required. Select the desired pitch for A4, start at a note of your choice. - Several pianos, with different inharmonicity profiles, can easily be tuned together. Simply select the same standard pitch for all pianos. STOPPERSTIMMUNG - PURE TWELFTHS EQUALTEMPERAMENT TUNIC only:pure Piano Tuner tunes the piano with the original Stopper temperament (after master piano builder B. Stopper, 1988) based on pure duodecimes (the interval that spans an octave and a fifth). It creates an amazing and clear sound on your instrument by the tunings stunning structural symmetry, making chords to appear as being pure tuned. The pure twelfths equal temperament tuning method has become a new standard in the concert halls in the past 30 years, and widely been used by professional piano and concert technicians worldwide. HARMONIC EQUIVALENTS AND EFFECTIVE PITCH Due to the inharmonicity of piano strings, the pitch of a piano tone typically deviates from that of a corresponding harmonic tone (e.g. approx. 0.8-0.9 Hz for A4, whereby the exact value depends on the non-linearity of the strings). TUNIC only:pure takes this effect into account by the method of "harmonic equivalents": For a given pitch (e.g. A4 at 440Hz), only:pure automatically tunes the instrument such that the best possible impression of a harmonic tone is perceived. Please note that this means that the actual pitch of an instrument tuned with only:pure typically differs by 0.8 - 0.9 Hz from the fundamental of corresponding tone with harmonic partials. NOTES REGARDING USAGE OF THE TUNING APP Depending on your device, prior to the first usage, you may need to set the microphone gain once in order to achieve satisfactory results. To do so, tap on the button "PITCH/Mic Gain" while playing some keys. Increase the microphone gain (initially set to 1.0) until the indicators move smoothly and/or the note recognition works reliably. While tuning, please ensure that your device is located as close as possible to the string that you're tuning, especially in the treble. In case the program reacts sluggish, you may also try to change a different microphone input, by tapping on the left microphone label. The current effective pitch (see preceding section) is displayed by the number in the top left area of the screen. Finally we note that TUNIC only:pure is primarily a tool for skilled and experienced piano tuners and concert technicians. Due to its high-responsiveness, the software may be difficult to control for beginners and part-time piano tuners.
