subsequence.constants.midi_notes
================================

.. py:module:: subsequence.constants.midi_notes

.. autoapi-nested-parse::

   MIDI note number constants.

   Maps note names to their MIDI note numbers (0–127). Convention: **C4 = 60** (Middle C),
   matching the MIDI Manufacturers Association standard and most DAWs (Ableton, Logic, Reaper).

   Notes are named ``<Pitch><Octave>`` for naturals and ``<Pitch>S<Octave>`` for sharps::

       import subsequence.constants.midi_notes as notes

       p.note(notes.A4, velocity=100)       # 69
       p.arpeggio(chord.tones(notes.E2))    # 40
       root = notes.C3                      # 48

   Range: C_NEG1 (0) through G9 (127). Sharps are provided (e.g. ``CS4`` for C♯4);
   flats are enharmonic equivalents (Db4 == CS4 == 61).
