Parts and track ideas

[odoare]

Following a discussion on parts and tracks on 2024-07-13

Part

Properties

• Tempo
• Time signature
• Number of Bars

Tracks : tables of events of unique type (one track per type)

Main tracks (defined by the main conductor)

• Chord event : {time, chord}

• Scale event : {time, scale}

Optional main tracks

• Nuance, dynamics : {time, nuance}
  Nuance can be a float between 0 and 1, eventually later converted to an int between 0 and 127.
  An enum-like thing could translate nuance names (piano, forte, fortissimo...) to actual values.

• Main theme (melody) : {time, note, duration, (velocity?)}

Tracks defined at the interpreter level

• Theme (if not defined globally or if interpreter wants its own theme)

• Nuance (same)

• Rhythm (for percussive instruments) : {time, (velocity?)}
  A multi-instrument percussion has multiple rhythm tracks (eg. a drummer with kick, snare, hi-hat...)

• Generic parameter : {time, value}
  Any parameter that a player can interpret, eg. any CC parameter of a synth

Proposal for accessing tracks

Tracks could be accessed in a folder way. Eg. to access the kick rhythm of the drummer part: drummer.get_track({"kick", "rhythm"}).

In a more general/global implementation, each interpreter can be a folder, the conductor level being the root level:

get_track({"drummer","kick","rhythm"})
get_track({"chords"})
get_track({"guitar1","melody"})

OSC implementation would not be far away!
