  <code>channel_base10  noteNumber_base16  pitch_base16.fractionalPitch_base32</code>
  <code>channel_base10  noteNumber_base16  pitch_base16.fractionalPitch_base32</code>


Upon loading a Chanopif file, all notes start in an inactive state. As each line is read, the specified note on the given channel becomes active (or is updated if already active) with its assigned pitch and fractional pitch. After the entire file is processed, any notes that have not been defined remain inactive.

* '''Overcoming 128-Note Limitations''': By combining multiple channels (up to 256 in MIDI 2.0), each with fully customized tuning for every note, composers can effectively bypass the traditional 128-note limitation of MIDI. This is especially beneficial for large-scale works requiring extensive microtonal ranges.

* '''Flexibility''': By assigning independant tuning configurations per channel, it becomes possible to create scales that do not rely on octave equivalences.

* '''High Precision''': At around 1.49 × 10^-6 cents per step, the resolution far exceeds what the human ear can typically discern, making it suitable for studio recording, live performance, or any scenario requiring advanced microtonal control. At 20000 Hz, the phase difference between two adjacent pitches is approximately 16 hours.

At 20,000 Hz, the maximum phase deviation caused by Chanopif’s rounding occurs only once every 16 hours.
* '''Data Efficiency''': By using the most concise syntax possible, compressing 7-bit words in hexadecimal and 25-bit words into 5 letters of 5-bit (base 32), it ensures optimal space savings in storage and transmission.

* '''Compatibility''': The format complies with the MIDI 2.0 standard, fully supporting the 7.25 pitch attribute for enhanced musical expression and precision.

* '''Standardized Microtonal Implementation''': By adopting a consistent '''402,653,184-EDO''' approach, Chanopif eliminates ambiguity over how fractional pitches are interpreted.

* '''Widespread Applications''': Chanopif can be used to compose music that extends '''beyond the standard 128-note limit''', allowing for large tuning systems, such as a full eight-octave [[72edo|72-EDO]] scale (576 notes required) with [[The Riemann zeta function and tuning|optimal Riemann Zeta stretch]] (no-octave equivalence multi-channel required). It also enables the development of new instruments, encourages experimentation with alternative scales, and supports hyper-accurate tuning for classical, jazz, electronic, and many other musical styles.

* '''Complete this Article''': Provide a variety of Chanopif file examples to help users understand the format, and offer a basic Python-based generator, validator, and parser as an initial toolkit. This will serve as a practical foundation for anyone who wishes to explore, customize, or contribute to Chanopif.
* '''Publish this Article''': Make the current article widely available, showcasing the Chanopif format and inviting readers to join or start development efforts. By engaging passionate developers, students, and hobbyists worldwide, Chanopif can evolve into a fully-realized standard without requiring the originator to singlehandedly manage its technical progress.
