«network of loosely connected nodes» by LFSaw

on 29 Apr'13 10:05 in synchronisationweak connection

Idea: network of loosely connected nodes. Each node has a dedicated pulse rate / phase. Inducing an irregular trigger signal influences the nodes to (gradually) adapt their pulsation freq (and phase?) to the one of the input. sound example: https://soundcloud.com/lfsaw/sync-weakconnection-tduty-time

	// the nodes, each takes its predecessor as input and estimates the duration between two events. 
	// Unfortunately, the starting point of Timer is '0' which we have to put into reasonable limits. System settles after about 15 seconds
	var nodes = (1..10).inject([input], {|last, item| 
		[TDuty.ar(max(0.25, Timer.ar(last.first)), 0, 1)] ++ last
	});

	// add a pitch to each
	nodes = nodes.collect{|node, i|  SinOsc.ar((4000 + (i*500))) * Decay2.ar(node, 0.01, 0.2)};

	// splay in stereo field
	Splay.ar(nodes);
