Minim Constant Methods Just outputs a constant value. Constructors ```Empty constructor for Constant. Sets value to 1.0. Constant() Constructor for Constant. Sets value to val. Constant(float val) ``` Parameters val — float: the constant value this will output Related UGen Example ```/* constantExample
is an example of using a Constant UGen to control the frequency of an Oscil. You can patch a Constant UGen into any input of any other UGen, which gives you an easy way of interactively controlling that input. In this case, you move the mouse left and right to change the frequency of the oscillator. You'll hear the frequency "stair step" because we don't smoothly change the value, we simply set it every frame.
