Synths return values

[halalkebabhut]

Hi,

I'm trying to find a method and syntax to get my synths to return values for specific parameters that are arguments in the SynthDef.

eg.

(
   SynthDef.new(\SawWave, {arg freq, sig, inBus, amp;
   sig = LFSaw.ar(In.kr(freq),0 ,0.2);
   amp = In.kr(inBus);
   Out.ar(0,[sig, sig]* amp );
   }).send(s);
   );

y = Synth.new(\SawWave,   [\freq, f, \inBus, b]);

How can I get y to return a frequency value without refering to f ?

if I use .get method all I get is the name of the Synth.

Is this possible at all?

There is an example in the Synth helpfile of how to use mySynth.get().

   get(index, action)
   getMsg(index)
      
      Query the server for the current value of a Control (argument). index is a control name or index. action is a Function which will be evaluated with the value passed as an argument when the reply is received.
      

Code:

s.boot;
(
SynthDef("help-Synth-get", { arg freq = 440;
Out.ar(0, SinOsc.ar(freq, 0, 0.1));
}).send(s);
)
x = Synth("help-Synth-get");
x.set(\freq, 220 + 440.rand);
x.get(\freq, { arg value; ("freq is now:" + value + "Hz").postln; });
x.free;

Keep in mind that every time you ask for a value from the server, it's asynchronous - aSynth.get does not return the value immediately because the client has to wait for the value to come back in an OSC message from the server.

Also - if you use the Ctk quark, you can query these values like so:

Code:

a = CtkSynthDef(\test, {arg freq = 440;
Out.ar(0, SinOsc.ar(freq, 0, 0.1))
});

b = a.new.play;
b.freq; // get the value of the freq arg

b.freq_(550); // set it to a new value

b.freq; // query it again

b.free

Hope that helps.

Thanks,

thats reduced my code significantly
