periodic random based object Random number generator. The periodicity factor (float between 0 and 1) determines the "periodicity" of the output, i.e. the probability of repetitions. A periodicity factor of 1 will result in a completely periodic output (= constant repetition of a single value), whereas a periodicity factor of 0 will result into a completely unperiodic behaviour.	from the library : Real Time Composition Library Format : Abstraction Environment : max / msp freeware Max 3.x / 4.x http://www.essl.at/software.html
