ACE Powers lets you raise a constant value to the power of the X input. There are three selectable constants which are useful within an analogue computer and modular synth environment: Y = 2^X is very useful for applying Volts/Octave control over linear parameters. Y = e^X is useful for creating exponential curves from linear inputs. Y = 10^X is most useful for representing a number in exponential form, or scientific notation.
