The third screenshot shows an example of a Temperament Bank set up to a typical Piano Stretch Curve. The PST also includes a Programmable Temperament Function with 5 user definable banks. The second screenshot shows the display for an E 440 Tuning Fork with the Calibration Dial enabled and set. This string rings bright, so the overtones are also dominant in the Display. The Fundamental appears as an Orange peak in the Spectrum Display. The first screenshot shows the display tuning a Guitar Low E string. When the rotation is stopped, the note is in tune. The Two-Group pattern rotates CCW when the input is flat, and CW when sharp. The outside Strobe Display works just like a classic rotating disk strobe tuner. The Strobe Display responds instantaneously to changes in pitch and is extremely sensitive. Fine tuning is accomplished by adjusting to stop rotation. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note Indicator.Īs the input approaches the desired Note, a Two Group pinwheel pattern becomes visible rotating in the Strobe Display. The Fundamental Indicator Tic on the Spectrum Display shows the Note of the Fundamental along the Note Dial, with the color designating the Octave. All overtones of the input are shown as peaks in the Spectrum Display pointing towards their corresponding Notes. The Note Dial is marked like a clock with the twelve notes of the Scale. The central Spectrum Display shows the input spectrum wrapped around the Display, with each Octave drawn in a separate color. 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 PST combines a radial Spectrum Display with a classic Strobe Tuner and Note Dial for an ultimate visualization of pitch and tone. However it's up to me to know how the instrument should be tuned.A General Purpose Chromatic Musical Instrument Tuner App with special Temperament and Piano Tuning Functions. Youngs, Kirnberger, Vallotti, Pythagorean, and meantone would be a decent short-list.īecause it will do any note, it works for any instrument. It would sure be handy if there was more than one "custom" memory - and some common temperaments as presets would be nice too. And the "custom" setting are remembered even if I switch to "equal". When in "custom", each tone of the scale can be shifted +- 35 cents. The menu lets me choose "custom" or "equal". One of my favorite features is the ability to un-equal the tuning temperament. So far I have seen no reason to lock it down to one particular octave, but I like that the option is there anyway. The reference can be shifted from A440 to between 415 Hz to 455 Hz. Never the less, with the widget on the right side accurately identifies the fundamental, so the tuning is fast and accurate. Due to harmonics, the strobes for notes other than the one sounding seem to show a tuning match - or near match. The 12 simultaneous tuners is a bit of a gimic. Notice: This app plays no piano sounds! It only allows you to visualize pitch from the microphone input.

If you are not sure if you understand using a waterfall strobe tuner, please download the Free inTuna A440 app from the App store (which can only tune 1 note: concert A = 440 Hz) and give it a try.įor custom intonations, you can individually vary the reference frequency of each string in 1 cent increments up to +-30 cents away from equal temperament. When the waves for a particular note synchronize or line up vertically, and stop leaning or shifting left (flat) or right (sharp), you are precisely in tune with an internal equally-tempered digital oscillator. Just watch the waterfall waveforms overlaid on each string. You can also see if plucking a string hard on a guitar causes the notes to "bend". With multiple strobe tuners, you can see if one pitch shifts in frequency while tuning another.
If you're really good, you don't even need to tune one note at a time. You don't need to wait for a needle to finish moving. You don't need to wait for a tuner to lock onto each note. With 12 simultaneous strobe tuners, you don't need to wait for your room or recording studio to become quiet enough. The multiple unique high contrast waterfall strobe visuals will quickly display the tuning in any of 12 note pitches and harmonics simultaneously. 12 Simultaneous Visual Strobe Tuners for any musical instrument, fast, accurate, and noise resistant, using the built-in mic on your iPad.
