Pbjorklund2 | SuperCollider 3.13.0 Help

Description

After an algorithm by E. Bjorklund. See paper by Godfried Toussaint.

NOTE: This class is by Juan A. Romero and gives ratios for durations instead of arrays with binaries as in the original Pbjorklund.

Class Methods

.new

Arguments:

k	The number of 'hits'.
n	The total sum of all the durations in the array.
length	Number of repeats.
offset	Skip at start.

Examples

a= Pbjorklund2(3, 8, 1).asStream;
4.do{a.next.postln};
