処理中にOSC(オープンサウンドコントロール)でチャックに信号を送るために「Play Amazing Notes」ボタンを作ったが、処理スクリプトを実行するとこれらのエラーメッセージが表示される。チャックとOSCとの統合処理

マイ処理コードは次のようになります。
import controlP5.*;
import oscP5.*;
import netP5.*;
OscP5 oscP5;
NetAddress dest;
ControlP5 cp5;
void setup(){
size(200,210,P3D);
background(0);
createControls();
//setUp Osc sending
oscP5 = new OscP5(this,12000);
dest = new NetAddress("127.0.0.1",6449);
}
void draw(){
background(0);
smooth();
}
void createControls(){
cp5 = new ControlP5(this);
cp5.addButton("playNote")
.setValue(0)
.setCaptionLabel("Play Amazing Notes")
.setPosition(10,10)
.setSize(180,50);
}
void playNote(){
println("play Note");
OscMessage msg=new OscMessage("/playNote");
oscP5.send(msg,dest);
}
とチャックコードです:
Mandolin m=> dac;
OscIn oin;
OscMsg msg;
6448 => oin.port;
"/playNote" => oin.addAddress;
while(true){
oin => now;
while (oin.recv(msg))
{
msg.address @=> string address;
if(msg.address=="/playNote")
{
Math.random2f(48,70) => float note;
note => Std.mtof => m.freq;
}
}
}
