play wav files in different bpms

I want to write an application that plays various wav files in different bpms.I have written a code and I want to know if thats ok or is there a more convinient way to do it?For example with LiveOutput.
Here is the code:
Sample[] mySample = new Sample[9];
int framerate=25;
int maincounter=0;
int[] bpm= {140,140,140,70,70,70,280,280,210}; //different bpms values for different files
int[] dlay= {0,5,10,0,5,10,0,7,0}; //for the files that have same bpm there is a factor of delay
int[] counter ={0,0,0,0,0,0,0,0,0}; //counter for every file
int[] mod = new int[9]; //an array for holding the time when to play the related wav
void initialize(){
for(int i=0;i<9;i++){
int j=i+1;
mySample[i] = new Sample(j + ".wav");
mod[i]=(framerate*60)/bpm[i]; //here I calculate the counter time when the play the wav file
}
}
void setup() {
size(200,200);
Sonia.start(this);
framerate(framerate);
initialize();
}
void loop(){
background(0);
maincounter++; //this is a main clock
for (int i=0;i<9;i++){
if(maincounter>=dlay[i])
counter[i]++; //every wav has its own clock and starts to increment when the delay time is passed
if((counter[i] % mod[i])==0){
mySample[i].play(); //if the time is ok play the file
}
}
}
public void stop(){
Sonia.stop();
super.stop();
}
1.The point I want to be sure is is this code really play files in the determined bpms or not?
thanks.
2. I also wnat to know how far I can go with this code. Can Sonia handle for example 25-30 sample files?
