    Class VexFlowConverter

    Helper class, which contains static methods which actually convert from OSMD objects to VexFlow objects.

    Methods

    • Convert a fraction to Vexflow string durations. A duration like 5/16 (5 16th notes) can't be represented by a single (dotted) note, so we need to return multiple durations (e.g. for 5/16th ghost notes). Currently, for a dotted quarter ghost note, we return a quarter and an eighth ghost note. We could return a dotted quarter instead, but then the code would need to distinguish between notes that can be represented as dotted notes and notes that can't, which would complicate things. We could e.g. add a parameter "allowSingleDottedNote" which makes it possible to return single dotted notes instead. But currently, this is only really used for Ghost notes, so it doesn't make a difference visually. (for other uses like StaveNotes, we calculate the dots separately)

      Parameters

      • fraction: Fraction

        a fraction representing the duration of a note

      • isTuplet: boolean

      Returns string[]

      Vexflow note type strings (e.g. "h" = half note)
