|
Combines an arbitrary number of patterns by evaluating a function (depth first traversal). When a stream ends it is recreated from its pattern until the top stream ends.
|
|
|
|
Examples::
|
|
|
|
code::
|
|
(
|
|
f = { arg vals;
|
|
vals.postln;
|
|
};
|
|
x = PstepNfunc(f, [
|
|
Pseq([1, 2, 3]), Pseq([4, 5, 6]), Pseq([7, 8, 9])
|
|
]).asStream;
|
|
50.do({ x.next });
|
|
)
|
|
|
|
(
|
|
f = { arg vals;
|
|
var r;
|
|
r = vals.copy.removeAt(0);
|
|
vals.do({ arg item; r = item / r.squared * 10 });
|
|
r
|
|
};
|
|
x = PstepNfunc(f,
|
|
[
|
|
Pseq([1, 2, 3], inf),
|
|
Pseq([2, pi, 1]),
|
|
Pseq([0.1, 3, 0.2, 3])
|
|
]
|
|
).asStream;
|
|
|
|
50.do({ x.next.postln });
|
|
)
|
|
|
|
// note that if the last pattern loops it will stick to that one:
|
|
(
|
|
f = { arg vals;
|
|
vals.postln;
|
|
};
|
|
x = PstepNfunc(f, [Pseq([1, 2, 3]), Pseq([10, 20, 30, 40]), Pseq([100, 200, 300], inf)]).asStream;
|
|
50.do({ x.next });
|
|
)
|
|
|
|
|
|
(
|
|
f = { arg vals;
|
|
vals.inject(1, { arg x, y; x * y })
|
|
};
|
|
x = PstepNfunc(f,
|
|
[
|
|
Pseq([1, 2, 3], inf),
|
|
Pseq([2, pi, 1]),
|
|
Pseq([0.1, 3, 0.2, 3])
