A control generator that emits a single rectangular pulse and then stays silent. Pre-delay sets how many samples elapse before the pulse begins, Width how long it lasts, and Amplitude its height. Separate Max pre-delay and Max width selectors (each 1, 10, 100, 1000 or 10000) multiply the pre-delay and width ranges so both can span from a handful of samples to very long intervals. It has no audio input or output, only a single control output, and is typically used to gate or enable other control blocks for a fixed span.
The effective pre-delay and width in samples are the Pre-delay and Width values each multiplied by their selected range factor; a sample counter drives the output to Amplitude while it lies between the pre-delay and the pre-delay-plus-width, and to zero otherwise. One control value is produced per tick, in step with WaveWarp's sample-per-sample engine.
