This is a clock generator and gate/trigger/clock (“pulses” generally) processor. It takes pulses generated externally or manually via a push button or internally via a clock generator and optionally sends them through a one-shot that transforms each source pulse into a pulse with a different, fixed width. Or not. Then it outputs the resulting pulse to one output jack, its inverse (on to off and vice versa) to another, a trigger on its rising edge to a third, and a trigger to a falling edge on a fourth. You can use this to generate gate clocks or trigger clocks, transform gates to triggers or vice versa, change the lengths of gates, and so on.
