In MIDI 2.0, '''Registered Per-Note Controller #3: Pitch 7.25''' provides a high-resolution method for defining pitch beyond standard 12-tone equal temperament (12-EDO).

The 32-bit data field for Pitch 7.25 is split into: | ||
7 bits for the integer part (the “traditional” note number in semitones). | |||
25 bits for the fractional part of a semitone. | |||
This gives 2^7 = 128 distinct note values (as in MIDI 1.0), each further divided into 2^25 microsteps, resulting in a total of 402,653,184 equal divisions per octave (12 semitones × 2^25). This extreme resolution allows for microtonal tunings with sub-cent precision. | This gives 2^7 = 128 distinct note values (as in MIDI 1.0), each further divided into 2^25 microsteps, resulting in a total of 402,653,184 equal divisions per octave (12 semitones × 2^25).
