of yourse that's also not too hard if you simply
create lots of synths, it will definitely glitch
[1].

yes, sure.
Many of the JITLib classes extend this scheme.
You can do livecoding with l-systems, e.g. using
Plsys:
http://swiki.hfbk-hamburg.de:8888/MusicTechnology/727
[1] this you could use to slowly tune the glitch:
s = Server.local;
s.boot;
SynthDef("numsynths",{
SendTrig.kr(Impulse.kr(0), 0, NumRunningSynths.ir);
Line.kr(doneAction: 2); // free self
}).send(s);
SynthDef("wastecpu",{
var dt = Rand(1, 5);
{ Line.ar(dur: dt, doneAction: 2) } ! 50; // free self
}).send(s);
(
q = q ? ();
q.numSynths = 0;
q.balance = 100;
// register to receive this message
OSCresponder(s.addr,'/tr',{ arg t,r,msg;
q.numSynths = msg[3].postln;
}).add;
fork {
inf.do {|i|
if(q.numSynths < q.balance) {
Synth("wastecpu");
};
Synth("numsynths");
0.1.wait;
}
}
)
// tune numSynths..
q.balance = 15;
PS fredrik has a glitch ugen, called Slub, but i
suppose you know that already..
