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. As the input approaches the desired Note, a Two Group pinwheel pattern becomes visible rotating in the Strobe Display. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note Indicator. 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.

In addition, there are several Special Measurement Banks used for String Inharmonicity characterization and Piano Stretch Curve Calculation. This can also be used for tuning alternate temperaments, pedal steel guitar setups, or special guitar intonation systems.
