Note API

The Note API provides functionality to convert music notes into their respective MIDI code and/or their frequency in Hertz, among other things. It it used in combination with computer.beep and note blocks (using OpenComponents).

• note.midi(n: number or string): number
  Converts a note in string form (e.g. A#4 or Gb3, see below) or a given frequency into the respective MIDI code
• note.freq(n: number or string): number
  Converts a note in string form (e.g. A#4) or a given MIDI code into the respective frequency
• note.name(n: number): string
  Converts a MIDI value back into a string; if you have a frequency to convert, just use note.name(note.midi(frequency))
• note.ticks(n: number): number
  Converts note block ticks (0-24) into MIDI code (34-58, respectively) and vice-versa. Useful for use with Note Blocks and OpenComponents
• note.play(tone: string or number,duration: number)
  Plays a note from a string or MIDI code via computer.beep with the specified duration
