Experimental live coding support a la Ndef

How about  this ? It would be nicer to start the new synth as the old one is fading out, but I didn't manage to do that...

(
Udef(\test, {
	UOut.ar(0, WhiteNoise.ar() )
})
)

(
Udef(\test, {
	UOut.ar(0, SinOsc.ar() )
})
)

(
x = UChain(\test, \stereoOutput);
y = x.gui;
y.autoRestart_(true)
)
