You are tripping over a common Client-Server-Architecture misunderstanding
here. The code inside a SynthDef is only executed *once* at
the client side to construct the Synth graph. You
can *not* set variables insides a SynthDef from client side GUI objects directly.
What you actually want is:
* A synthDef with arguments which represent the values you want to change.
* A client side GUI with callbacks that *set* the server-side
Synth arguments on update.
I will try to illustrate, but I dont use SCUM, so its untested,
but I am pretty sure you'll get the idea:
SynthDef("onetwoonetwo",{ arg out=0, freq=440;
Out.ar(out,
SinOsc.ar(freq, 0, 0.5)
)
}).send(s);
n=Synth(\onetwoonetwo);
w = SCUMWindow.new;
w.title = "Slider example";
w.initialSize = Size(20, 300);
c = SCUMVBox( w );
v = SCUMSlider(c, { |v|
v.expand = 1;
v.fill = 1;
v.bgColor = Color.white;
v.fgColor = Color.black;
v.action = {
n.set(\freq, (v.value * 100)+400);
};
v.doAction;
});
w.show;
