[OSC] Bind custom vars to Ugen parameters with osc

[kapitan]

Hi,

i have not found how can i bind my controllable
variable to the ugens arguments created in scsynth.

i mean not to use sclang (but JCollider),
so i have to find a way to do this
with osc messaging.

How can i do?

[Sciss]

JCollider has a Node and a Synth class that are very similar to the  
classes with the same names in sclang, so setting node controls is  
practically the same. You might want to read their respective help  
files in SC3.

But this is my example in sclang:
 (
SynthDef("tutorial-args", { arg freq = 440, out = 0;
Out.ar(out, SinOsc.ar(freq, 0, 0.2));
}).send(s);
)

x = Synth("tutorial-args"); // no args, so default values
y = Synth("tutorial-args", ["freq", 660]); // change freq
z = Synth("tutorial-args", ["freq", 880, "out", 1]);

Are freq and out an Ugen.ir(something) in
the definition of the JCollider Synthdef?

That is, have not understand that, cause JCollider
doesn't have function i don't know how to declare
vars.

Sorry i'm a newbie :)

[Sciss]

ok, so you want to build synthdefs with jcollider, not just control  
existing synths. below is an example, you see this is much more  
effort than sclang, and in particular SynthDef composition is not  
what jcollider was created for. so you need to instantiate a Control  
UGen. As Synth is missing a two argument constructor (could go on the  
feature-request-list), i'm using Synth.head here for brevity.

import de.sciss.jcollider.*;

public class Test {
        public static void main( String[] args ) {
          try {
                UGenInfo.readBinaryDefinitions();
                Server s = new Server( "default" );
                s.start();
               
                Control ck = Control.kr( new String[] { "freq", "out" }, new float
[] { 440f, 0f });
                new SynthDef( "tutorial-args", UGen.ar( "Out", ck.getChannel
( "out" ), UGen.ar( "*", UGen.ar( "SinOsc", ck.getChannel( "freq" )),  
UGen.ir( 0.2f )))).send( s );
                s.sync( 4f );

                Group g = s.asTarget();
                Synth x, y, z;
                x = Synth.head( g, "tutorial-args" ); // no args, so default values
                Thread.sleep( 1000 );
                x.free();
                y = new Synth( "tutorial-args", new String[] { "freq" }, new float
[] { 660 }, g ); // change freq
                Thread.sleep( 1000 );
                y.free();
                z = new Synth( "tutorial-args", new String[] { "freq", "out" }, new  
float[] { 880, 1 }, g );
                Thread.sleep( 1000 );
                z.free();
                System.exit( 0 );
          } catch( Exception e1 ) {
                e1.printStackTrace();
                System.exit( 1 );
          }
        }
}

p.s. there are other language possibilities. i have started to  
examine Scala which is a very nice language in that it is statically  
typed but has large type inference mechanism so you effectively save  
a lot of typing, plus generics (well, you've got them in java 1.5)  
plus closures (well, you might get them in java 1.7), and you can  
access any standard java class without fuss. here's is how it would  
look in scala:

import de.sciss.tint.sc._
import de.sciss.tint.sc.Predef._

val s = new Server( "default" )
val df = SynthDef( "test3", { "out" kr 0; "freq" kr 440; "amp" kr  
0.5f; Out.ar( "out", SinOsc.ar( "freq" ) * "amp" )})
df.send( s )

val x = Synth.spawn( "test3" )
x.free

val y = Synth.spawn( "test3", List( "freq" -> 666 ))
y.free

val z = Synth.spawn( "test3", List( "freq" -> 333, "out" -> 1 ))
z.free


so despite being a typed language, you come pretty close to the  
brevity of sclang code.

Very very helpful.

So this is. I've to try and try, my questions are
not finished :) .

I'm working on the Pause Ugen by now,soon i'll post
some code. thanks

I suppose that on new Synth i can use
you Synth.set or setn messages, right?

So i can message the controlled var
and set it.

The diffcult part i think is the getChannel
on the Control. Is hard to understand
why a channel retrieving a var...

yes.

this is because JCollider is much closer in this case to how the  
actual Synth looks like. SuperCollider is much more abstract and as a  
result much more ergonomic in this case, since they did the trick of  
re-interpreting the role of a Function. You know, { .... } is a  
function in SuperCollider, so the trick is instead of requiring  
explict Control.ir, Control.kr, LagControl.kr, and TrigControl.kr  
UGens, to use the reflexion features of the language to create those  
UGens invisibly from the arguments passed to the function.

So two things: first you are not dealing with variables in a UGen  
graph function in supercollider, but with arguments to that function.  
The graph builder in SynthDef interprets those arguments and  
evaluates (calls) the function with Control UGens passed in. So they  
appear as local variables or arguments, but in fact under the hood is  
a Control UGen.

That UGen for efficiency is implemented in a multichannel fashion, so  
all the control rate controls are output from one single Control.kr  
ugen (they represent that UGen's output channels, hence the need to  
call getChannel in JCollider which accesses those channels), and one  
single Control.ir for scalar rate controls, etc.

Of course, one could have thought up a more elegant way for  
JCollider, but i just stick to that simple solution of requiring an  
explicit UGen. Also because JCollider is more targeted to application  
building and not really live coding, so the bits of extra effort are  
usually not that problematic.

[CUT]

My first right SynthDef?

Control tk = TrigControl.kr(new String[] {"t_buf"}, new float[] {-1.0f});
Control ck = Control.kr(new String[] {"i_rate","i_start", "i_loop"}, new float[] {1.0f, 0.0f, 0.0f});
mybuffer = Buffer.cueSoundFile(ScApp.getApplication().getServer(),wav.getAbsolutePath(),0,2);
             
//PlayBuf.ar(numChannels,bufnum,rate,trigger,startPos,loop)
GraphElem g = UGen.ar ("PlayBuf",2, UGen.ir(mybuffer.getBufNum()),ck.getChannel("i_rate"),
          tk.getChannel("t_buf"),ck.getChannel("i_start"),ck.getChannel("i_loop"));        
             
SynthDef def = new SynthDef( "Play-Buffer", UGen.ar( "Out", UGen.ir( 0 ), g));
Synth synth = Synth.basicNew("Play-Buffer", ScApp.getApplication().getServer(),13000 );
ScApp.getApplication().getNodeWatcher().register(synth);

def.send( ScApp.getApplication().getServer(),synth.newMsg(ScApp.getApplication().getServer().asTarget()));


By now i set args with sclang and a message bundle,
and it works...but ouch what a pain to the eyes.

With cueSoundFile works and with read don't.

But i cannot really find a get method on node
nor a getMsg...how can i retrieve the value
of a Control?

With a getRate on the Control object?

[Sciss]

ahhh, it's true those methods were missing.

i added them, so please check out SVN revision 11. i have had no time  
to test them, so please report back if there are any issues:

Synth
        get
        getn
        getMsg
        getnMsg

get and getn are implemented in a quasi-synchronous way as they are  
not asynchronous server commands and hence should only take s.latency  
* 2 time. so instead of passing in a doneAction, these methods return  
the queried values directly. otherwise you would need to set up an  
OSCResponderNode and send out the getMsg or getnMsg yourself.

So, my today tests have as results that direct Synth.get and getn methods
retrieves Control values only. If you want to retrieve a TrigControl
value, you have to set up an OSCResponder Node. That is:

OSCResponderNode rn = new OSCResponderNode(ScApp.getApplication().getServer(), "/n_set", new OSCListener() {

                    public void messageReceived(OSCMessage msg, SocketAddress sender, long time) {
                      //garbage
                    }
                });
               
if (!rn.isListening())
     rn.add();
               
rn.removeWhenDone();
               
ScApp.getApplication().getServer().sendMsg(this.execsynth.getMsg("t_pause"));
//other garbage

Here t_pause is a TrigControl for the PauseSelf Ugen.
I really have not understand the difference between Control
and TrigControl, i have to inspect the docs :-D .

Bye.

I was wrong, the TrigControl are not taken with the get methods
the n-set return me only 0.0f values.
