SuperCollider Ndef controls Processing(?)

in Integration and Hardware • 5 months ago

Hello all,

I am trying to make an Ndef to communicate with processing..

In SC I have something like:

Ndef(\test).play;

Ndef(\test, {

var freq_1, amp_1, etc

freq_1 = Array.fill(8, {

LFDNoise3.ar(0.01).range(400.0, 800.0)

});

amp_1 = ......

How can possessing read from freq_1 and change the size of a circle for example??

Best,

i

Copy code

//--supercollider code:
(
Ndef(\test).play;
Ndef(\test, {
var freq_1;
freq_1 = Array.fill(8, {
LFDNoise3.ar(1).exprange(400.0, 800.0); //x positions
});
SendReply.ar(Impulse.ar(60), '/freqLFOs', freq_1); //60 is updaterate (fps)
Splay.ar((SinOsc.ar(freq_1, 0, 0.1)));
});
n= NetAddr("127.0.0.1", 9876); //for sending to processing
OSCFunc({|msg|
//msg.postln; //debug
n.sendMsg(*msg);
}, '/freqLFOs');
)

Copy code

import oscP5.*;
OscP5 oscP5;
float[] freqs= new float[8];
void setup() {
size(800, 600, P2D);
frameRate(60);
oscP5= new OscP5(this, "127.0.0.1", 57120, 9876, "oscEvent");
}
void draw() {
background(0);
for (int i= 0; i<8; i++) {
ellipse(freqs[i], (i*(height/8))+30, 30, 40);
}
}
void oscEvent(OscMessage oscIn) {
if (oscIn.checkAddrPattern("/freqLFOs")) {
if (oscIn.checkTypetag("iiffffffff")) {
for (int i= 0; i<8; i++) {
freqs[i]= oscIn.get(i+2).floatValue();
}
}
}
}
