+some simple live code to get in
+<code>
+code::
+d = (); // create a new environment
+d.push; // push it to current
+// this synthdef can be changed on the fly, but the synth will
+// not change from this. use expression [1] for replacing a given synth

+	Out.ar(out,

+)
+// send a first synth:
+~s1 = Synth(\x);
+// [1]
+// now you can play around with these lines, as well as with the synth def above
+~s1 = Synth.replace(~s1, \x, [\freq, 200000]);
+~s1.set(\freq, 8000);
+// add a bus:
