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.

• Note set · Letter names

  quantized
  Db4

  Path note → note-set

• Pitch class · Pitch-class number

  lossy
  1

  Path note → pitch-class

  • Drops octave, cents, frequency. A note collapses to its pitch class, discarding register and tuning.

• Grid position · Cells col,row (optional layout@origin: prefix)

  quantized
  aura@C3:1,3

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

  • 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.

• Note distribution · MIDI : weight pairs

  quantized
  61:1

  Path note → note-set → note-space

• Pitch-class set · Pitch-class numbers

  lossy
  1

  Path note → note-set → pc-set

  • Drops octave, register, duplication, order. A note set collapses to the unordered set of its pitch classes.

• Point set · Semitone offsets

  lossy
  0

  Path note → note-set → point-set

  • Drops root, register. A note set keeps its shape as offsets from its lowest note and forgets where it sits.

• Pitch-class distribution · Twelve weights

  lossy
  0,1,0,0,0,0,0,0,0,0,0,0

  Path note → note-set → note-space → pc-space

  • Drops octave, register. Folds 128 MIDI bins into 12 pitch-class bins, keeping the weights.

• Set class · Forte name

  lossy
  1-1

  Path note → note-set → pc-set → pc-set-analysis

  • Drops octave, register, duplication, order. A note set collapses to the unordered set of its pitch classes.
  • Drops transposition. The set's Tn class (Forte name with A/B, prime form); the transposition is dropped.
