La Koron Tuner is specially designed to tune Iranian instruments that can play quarter tones. Since the interval between notes in each Dastgah and to some extent in each maestro’s viewpoint is slightly different, we have developed a capability with which the instrument can be tuned. It is also possible to customize the 24-equal temperament by changing the interval between the notes so that you can tune your instrument the way you want.
