  /**

  + * 'partialCount' offers an alternative way to set the number of used partials.
  + * When partialCount is 0, the maximum number of partials are used when representing
  + * the waveform using the periodicWave. When 'partials' is set, this value is
  + * not settable, but equals the length of the partials array.
  + * @example
  + * osc.type = 'sine'
  + * osc.partialCount = 3
  + * //is equivalent to
  + * osc.type = 'sine3'
  * @memberOf Tone.Oscillator#
  * @type {Number}
  * @name partialCount
