  * Sets the filter type. The 24db filter is more aggressive. More types might be added in the future.
  * @name ftype
- * @param {number | Pattern} type 12db (default) or 24db
+ * @param {number | Pattern} type 12db (0), ladder (1), or 24db (2)
  * @example
  * note("c f g g a c d4").fast(2)
  * .sound('sawtooth')
