Effective resolution = 100 cents / 2 14 =. The next two bytes (14 bits) specify the fraction of 100 cents above the semitone at which the frequency lies. The first byte of the frequency data word specifies the highest equal-tempered semitone not exceeding the frequency. The frequency range starts at MIDI note 0, C = 8.1758 Hz, and extends above MIDI note 127, G = 12543.854 Hz. "Frequency data shall be defined in which are fractions of a semitone. The frequency data format allows for the precise notation of frequencies that differ from equal temperament. If ƒ is a frequency, then the corresponding frequency data value d may be computed byĭ = 69 + 12 log 2 ( f 440 H z ). 6.2 Microtonal music software supporting MTS.
