timing problem

I have a problem that plays different sample files.3 of them play once at six frames.3 of them play once at 12 frames. 2 of them play once at 24 frames.The synchronization between the samples are ok.However sometimes the time when files should play delays.What can cause that problem.
here is the code:
Ses[] sesler=new Ses[8];
BFont font;
int framerate1=25;
int[] bpm= {12,12,12,6,6,24,24,9};
//------------------------------------------------
//----------------------------------------------------------------------
void initialize(){
for(int i=0;i<8;i++){
int j=i+1;
sesler[i] = new Ses(random(10,290),random(10,230),int(random(0,255)),int(random(0,255)),int(random(0,255)),bpm[i]/7*2,bpm[i],j);
}
}
void setup() {
ellipseMode(CENTER_DIAMETER);
size(320,240);
font = loadFont("BauerBodoni.vlw.gz");
textFont(font,20);
//----------------------------------------------
Sonia.start(this);
framerate(framerate1);
initialize();
}
void loop(){
background(255);
for (int i=0;i<7;i++){
sesler[i].update();
sesler[i].execute();
}
}
public void stop(){
Sonia.stop();
super.stop();
}
//////////////////////////////////////////////
class Ses {
////////////////////////////7
float x,y;
int r,g,b;
int low_rad;
int rad;
//////////////////////////////
int bpm;
int counter=0 ;
int mod ;
Sample _sample;
int wavno;
Ses(float x1,float y1,int r1 ,int g1,int b1,int rad1,int bpm1,int fname){
x=x1;
y=y1;
r=r1;
g=g1;
b=b1;
low_rad=rad1;
rad=low_rad;
bpm=bpm1;
mod=bpm;
println(mod);
_sample= new Sample(fname + ".wav");
wavno=fname;
}
void execute(){
float time;
fill(r,g,b,90);
ellipse(x,y,rad,rad);
fill(0,0,0);
text(bpm + ".",x,y);
if((counter % mod)==0){
_sample.play();
time=millis();
rad=low_rad;
}
}
void update(){
rad++;
counter++;
/*t ytemp=random(-1,1);
if(x>10 && x<290)
x += xtemp;
if(y>10 && y<290)
y += ytemp;*/
}
}

i'm not 100 % sure, but i think this is due to timing problems in java. it depends on the system you are running on and how many other processes are running at the same time. anyway, i don't have a solution to this except not to rely on framerate(). maybe sonia implements a better timing?

Do you think ,instead of using samples,liveoutput data can work?
