Bug or by design? Ppar pulling an event from upstream for every internal/parallel stream

I think @scztt has tried something like that too

PparChain.sc

PparChain : Pchain {
	var <>patterns;
	*new { arg ... patterns;
		^super.newCopyArgs(patterns);
	}
	<> { arg aPattern;
		var list;
		list = patterns.copy.add(aPattern);
		^this.class.new(*list)
	}

Pdef(\test, PparChain(
	// Duration of output events are pulled from the first pattern....
	Pbind(\dur, 0.25),
	
	// Additional patterns are played independently and
	// the last played event is merged every time the first
	// pattern yields
	Pbind(
		\dur, 1.4,
		\degree, Prand([1, 3, 6], inf),

Fairly long discussion here on that: Time-aware merging of two Event Pattern streams

From that it looks like @totalgee’s version won out with some (proposed) changes

		list = patterns.copy.add(aPattern);
