Abstract

A multi-tap delay has a graphical user interface in which each delay tap is represented by a bar on a time line. The bars are oriented across the time line, the position of each bar on the time line specifying the amount of delay time of the represented delay tap. The length of each bar specifies the value of another parameter of the represented delay tap.
