Delay modules hold the input signal for some amount of time using an internal circular buffer. This buffer is instantiated with a size maxDelay. At runtime, currentDelay is set to control the time constant for the maxDelay buffer. Most delays update currentDelay instantaneously, but smoothed(interpolated) delays are provided if the final product needs a varying delay.
