Converting into another concept may need context this value does not carry (a root, an octave, a key). Where it is missing the library assumes a default and says so; where a step drops information it is listed.

• Point set · Semitone offsets

  quantized
  0-17

  Path interval → point-set

  • Drops cents. 8/3 is 1698.045¢, -1.955¢ from 17 semitones; the deviation is kept on the value but dropped by semitone notations.

• Note set · Letter names

  quantized
  C4-F5

  Path interval → point-set → note-set · needs root, octave

  • Assumed root C. No root was given, so the value is read from C.

  lossy
  aura@C3:3,0 5,3

  Path interval → point-set → note-set → grid-position · needs root, octave, layout

  • Assumed root C. No root was given, so the value is read from C.
  • Assumed octave 4. No octave was given, so octave 4 is used.
  • Assumed layout aura. No layout was given, so positions are read on the aura layout.
  • Assumed root C3. No root was given, so the value sounds above C3.
  • Drops cents. 8/3 is 1698.045¢, -1.955¢ from 17 semitones; the deviation is kept on the value but dropped by semitone notations.
