[Koto Tuner]
The simple user interface with noise filtering can help you tuning the 13 strings without any setting while activating the APP. When you pull the Koto string, the pitch will be shown on the panel for the individual string by indicating signal high or low.
[Function Description]
▪ Calibrate Piano Sound : Click on an open string then calibrate the sound with your Koto.
▪ A4 Frequency adjustment: choose 428~452 frequencies for A4 string.
▪ Total 18 kinds of tuning modes are available.
▪ The scale for precision tuning is 5 cents for every sub-bit. The blue line represents the open strings start from. The green arrow means pitch is accurate and it will turn white once the pitch difference exceeds more than a sub-bit.
▪ The complete function, will visually tell you the pitch is good or not by lighting green or white. Users can easily adjust the string by the lighting arrow shown on the scale.
