Now updated for Windows 8.1 with better performance and device compatibility! The issue with using modTuner on a Surface 2 is resolved in this release. modTuner is a sophisticated automatic chromatic tuner suitable for tuning a wide range of musical instruments including guitars, basses, ukuleles, violins, violas and cellos. Its large, easy to read display is ideal for tuning even at a distance, and the carefully designed white-on-black appearance is ideal for use in dark performance environments. modTuner uses a sophisticated digital signal processing algorithm to accurately and reliably detect the fundamental frequency of the note being played. modTuner’s background graphic glows when a reliable tone is detected, providing you with greater confidence while tuning. Although very easy to use, modTuner has a number of advanced features including Drop/Capo tuning, Concert A calibration, High Sensitivity and Noise Filter modes. Drop/Capo enables drop or capo tuning, along with transposition which can be used to change keys for instruments played in a key other than C, for example alto saxophones (E flat) or trumpets (B flat). Concert A can be calibrated in steps of 0.1 Hertz to allow you to match the tuning of another instrument. modTuner can listen to another instrument to calibrate Concert A, or you can select a desired frequency directly. The High Sensitivity mode is provided to help when tuning certain instruments that may not be detected as easily by modTuner. The Noise Filter listens to your environment and reduces or eliminates noise that may make tuning difficult. modTuner automatically uses the sound source selected as Windows' default recording device, enabling it to be used with almost any sound source Windows recognizes. modTuner; the reliable chromatic tuner that makes it easy for you to keep your instruments in tune.
