This device manipulates clock pulses in three ways. “Humanize” sets the amount of delay randomly applied to clock pulses. “Improbability” increases the likelihood that a clock pulse will be held back from being passed through. Finally, “swing” will delay every other pulse to change the feel. It works with either external 5V clock sources or can generate its own clock.
