Sets the global seed value for all x-class noise generators, as well as other opcodes that use a random call, such as grain. rand, randi, randh, rnd(x), and birnd(x) are not affected by seed.
ival – value to be used as the random generator(s) seed value
Use of seed will provide predictable results from an orchestra using with random generators, when required from multiple performances.
When specifying a seed value, ival should be an integer between 0 and 232. If ival = 0, the value of ival will be derived from the system clock.
