object MouseY extends Serializable

A UGen that maps the vertical screen location of the mouse to a given linear or exponential range. The lo value corresponds to the bottom of the screen, and the hi value corresponds to the top of the screen (not vice-versa).

This UGen is useful for testing purposes. Mouse interaction with the regular desktop and windowing system is in no way altered by running this UGen.

Examples
// control sine frequency
play {
  val freq = MouseY.kr(100, 4000, 1)
  SinOsc.ar(freq) * 0.1 * AmpComp.kr(freq)
}

    lo

    value when the mouse is on the bottom side of the screen. Note: this value is never reached, because the maximum mouse coordinate is one pixel less than the screen height. For example, if the screen height is 900, lo is 0.0 and hi is 1.0, the minimum value output is 1.0 - 1.0 * 899.0/900 = 0.001111 .

    hi

    value when the mouse is on the top side of the screen

    warp

    curve shape. Either zero (default) for a linear mapping, or 1 for an exponential mapping. Note: When using exponential mapping, make sure the lo value is greater than zero, otherwise NaN values will be output.

    lag

    60 dB decay time of a lag-time smoothing. Use zero to avoid any smoothing.
