Precision Strobe Tuner vs Temperaments

Precision Strobe Tuner 2.0 A General Purpose Chromatic Musical Instrument Tuner App with special Temperament and Piano Tuning Functions. The PST combines a radial Spectrum Display with a classic Strobe Tuner and Note Dial for an ultimate visualization of pitch and tone. The Strobe Display is highly sensitive with response speed that is practically instantaneous and has long been the preferred tool for piano tuners and instrument technicians. The central Spectrum Display shows the input spectrum wrapped around the Display, with each Octave drawn 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 pointing towards their corresponding Notes. The Fundamental Indicator Tic on the Spectrum Display shows the Note of the Fundamental along the Note Dial, with the color designating the Octave. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note Indicator. 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 previews show a general strobe display demonstration, an example of using the calibration function to measure the accuracy of a tuning fork and an example of guitar string tuning. The first screenshot shows the display tuning a Guitar Low E string. The Fundamental appears as an Orange peak in the Spectrum Display. This string rings bright, so the overtones are also dominant in the Display. The second screenshot shows the display for an E 440 Tuning Fork with the Calibration Dial enabled and adjusted. This Fork is 2.9 cent Flat. The PST also includes a Programmable Temperament Function with 5 user definable banks. The third screenshot shows an example of a Temperament Bank set up to a typical Piano Stretch Curve. This can also be used for 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. The final screenshot shows the Input Signal Scope/Spectrum Display Page. The Detailed Operation Manual can be viewed here: www.precisionstrobe.com

Temperaments: Tune your music and your ears. Temperaments is an application for learning about musical tunings and temperaments used throughout history. Want to play Bach in a tuning he actually used? Would you like to try early music as it was heard at the time? How about composing new music with an unconventional tuning? Temperaments tunes your music and your ears. Temperaments uses MIDI to retune your music on the fly. You can play any standard MIDI file, apply a temperament, and hear the result in real time. You can connect an external keyboard, let Temperaments retune your performance, and send it to any synthesizer you choose. You can even record your music to standard MIDI files and export them to play on any sequencer. Your recordings can be sent to anyone via email. They can be dropped onto Dropbox, and you can tell the world about them on Facebook, all from within Temperaments. Temperaments includes twenty six temperaments in addition to Equal Temperament, with both meantone and unequal-interval types. You can switch back to Equal Temperament instantly just by pressing a button for instant comparison - even while notes are sounding. You can even change to an entirely different temperament instantly, any time, even in the middle of a performance. Temperaments includes a large, expandable display showing the differences between Equal Temperament and a chosen temperament. And, of course, you can select any note to be the root key of any temperament, so that your temperament matches the key of any file or performance. Use Temperaments to learn about nonstandard tunings. Use Temperaments to compose new music in unusual ways. Or experiment with applying a temperament to your MIDI files. Any way you want to use it, Temperaments tunes your music and your ears.
