Detailed Description

ConstantUG simply writes a constant to its output patchpoint.

ConstantUG produces a constant value. Since you can set the value of a patchpoint directly through the MKSynthData method setToConstant:, you rarely need instances of this class. However, a ConstantUG object can be used to initialize, on each tick, a constant-valued patchpoint that may have been written to during the previous tick. For example, you can implement additive synthesis by creating a patch in which each oscillator reads a patchpoint, adds its own signal into the value, and then writes the sum back to the same patchpoint in preparation for the next oscillator. In this case, you would use a ConstantUG to clear the patchpoint before the first oscillator reads it.
