Cycling '74 RNBO RNBO Math Generate random numbers without duplicates

Outputs random numbers and keeps track of each number that has been generated. When all numbers up to the maximum (set via an argument or the right inlet) have been output, a bang is send out the right outlet.

Maximum size of output chunk (default: 1)

Sets the range of possible output values. Output values are 0 indexed. Changing this value will clear the internal array of used numbers.

Seed to get predictable results

Sets a seed state for the random values, so that randomized results will be predictable each time the code is run.

Automatically reset when the all numbers have been used

When enabled the urn object will automatically clear itself once all numbers in the range have been used.

Clear the list of already chosen numbers

Clear the list of already chosen numbers. Note that this does not reset the object to the original seed state.

Remove duplicates at the beginning of a new series

When enabled, the first number generated at the start of a new series (after the clear message) will never match the final number of the previous series.

Seed to get predictable results

Sets a seed state for the random values, so that randomized results will be predictable each time the code is run.

Maximum size of output chunk (default: 1)

Sets the range of possible output values. Output values are 0 indexed. Changing this value will clear the internal array of used numbers.

Output a random number

A bang or number in the left inlet causes urn to output a number between 0 and one less than the value of the size attribute. Each number in the range can only be output once until the object is cleared.

Maximum size of output chunk (default: 1)

Sets the range of possible output values. Output values are 0 indexed. Changing this value will clear the internal array of used numbers.

Random Number Output

The number chosen. This value will be between 0 and one less than the maximum value as determined by the size attribute.

Bang if All Numbers in Range Chosen

Send a bang when every number in the range has been chosen.
