* '''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. | * '''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.

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. | * '''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. | ||
