The Precision Strobe Tuner is a General Purpose Chromatic Musical Instrument Tuner App with special Temperament and Piano Tuning Functions.
The PST combines a classic Strobe Tuner Display with a radial Spectrum Display and Note Dial for the ultimate visualization of pitch and tone. The Strobe Display is highly sensitive with a response speed that is practically instantaneous, it has long been the preferred tool for piano tuners and instrument technicians.
The central Spectrum Display shows the input spectrum wrapped around the Display once per Octave, with each Octave shown in a separate color. The Note Dial is marked like a clock with the twelve notes of the Scale. All overtones of the input are shown as peaks in the Spectrum Display radiating out towards their corresponding Notes on the Note Dial. The Fundamental Indicator Tic on the Spectrum Display designates the Note of the Fundamental along the Note Dial, with the color indicating the Octave. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note.
As the input approaches the desired Note, a Two Group pinwheel pattern becomes visible rotating in the Strobe Display. Fine tuning is accomplished by adjusting to stop rotation. The Strobe Display responds instantaneously to changes in pitch and is extremely sensitive. The outside Strobe Display works just like a classic rotating disk strobe tuner. The Two-Group pattern rotates CCW when the input is flat, and CW when sharp. When the rotation is stopped, the note is in tune.
The PST also includes a Programmable Temperament capability with 5 user definable memory banks. These can be used for setting up piano stretch curves, tuning alternate temperaments, pedal steel guitar setups, or special guitar intonation systems.
In addition, there are several Special Measurement Banks used for String Inharmonicity characterization and Piano Stretch Curve Estimation. Individual strings can be characterized by measuring the Fundamental and 2nd Harmonic separately. By careful selection of a few representative measurement points, a reasonable smooth fit Piano Stretch Curve can be generated. Any number of measurements can be used.
Whatever your tuning needs, the Precision Strobe Tuner will show you just what you need to see. Read the Operation Manual for complete details.
