Pclump : FilterPattern : Pattern : AbstractFunction : Object

A pattern that takes another pattern and groups its values into arrays.
Subclasses: Pflatten


Groups the source pattern into arrays whose size is given by n. Similar to SequenceableCollection: -clump.

E.g. If the source pattern has 5 elements and you choose a clump size of 2, the new pattern will return two arrays containing 2 elements and a final array containing 1 element.

Class Methods, pattern)



An integer, or a pattern that returns an integer. This integer will determine the size of the next clump.

.n = value


// This will give you the sequence: [1, 2] [3] nil
// Note that the last grouping is just the remainder of the pattern (in this case [3]).
x = Pclump(2, Pseq([1,2,3], 1)).asStream;;;;

Play some random chords:

  \degree, Pclump(Pseq([3, 3, 4, 2, 4, 2, 4], inf), Pseq([1, 3, 5, 7, 9], 8), inf),
  \dur, 1).play
