Ptpar embed event streams in parallel, with time offset

superclass: ListPatterns

Embeds several event streams so that they form a single output stream with

all their events in temporal order, providing a global offset for each.

When one stream ends, the other streams are further embedded until all have ended.

Ptpar(list, repeats)

list: list of pairs of times and patterns: [time, pat, time, pat .. ]

repeats: repeat the whole pattern n times (default: 1)

// see the delta values in the resulting events

(

var a, b, c, t;

a = Pbind(\x, Pseq([1, 2, 3, 4]), \dur, 1);

b = Pbind(\x, Pseq([10, 20, 30, 40]), \dur, 0.4);

c = Ptpar([0.0, a, 1.3, b]);

t = c.asStream;

20.do({ t.next(Event.default).postln; });

)

// sound example

(

var a, b;

a = Pbind(\note, Pseq([7, 4, 0], 4), \dur, Pseq([1, 0.5, 1.5], inf));

b = Pbind(\note, Pseq([5, 10, 12], 4), \dur, 1);

Ptpar([ 0.0, a, 1.3, b ]).play;
