    isTarget: boolean;

}

Properties

scaleDegree: string

The scale degree of this note (e.g., "I", "II", "-III", "+V"). Corresponds to positions in the SCALE_DEGREES array.

noteDuration: string

Rhythmic duration of the note using standard musical notation. Examples: "4n" = quarter note, "8d" = dotted eighth, "16t" = sixteenth triplet

isTarget: boolean

Whether this note should be emphasized or highlighted during playback. Target notes are typically structurally important in the pattern.

velocity?: number

Optional MIDI velocity value (0-127) for dynamic expression. Higher values result in louder playback.
