Making the same code work for more sensors.

hi there, wrote code make single light dependant resistor activate led light , send midi messages laptop:

code: [select]

int lightpin =0;
int ledpin =9;
int treshold = 400;
int lightlevel = 0;


void setup()
{
 pinmode(ledpin, output);
 serial.begin(9600);
}

void loop()
{
 int lightlevel = analogread(lightpin);
 serial.println(lightlevel);
 if (lightlevel >= treshold){
   switchled();
   delay(500);
 }
}


void switchled(){

 if (digitalread(ledpin) == high){
   do {
     digitalwrite(ledpin,low);
     midi_tx(144,60,127);
     delay(100);
     midi_tx(128,60,127);
     delay(100);      
   }
   while(analogread(lightpin) > treshold);
 }
 else if (digitalread(ledpin) == low){
   do {
     digitalwrite(ledpin,high);
     midi_tx(144,61,127);
     delay(100);
     midi_tx(128,61,127);
     delay(100);
   }
   while(analogread(lightpin) > treshold);
 }
}

// code midi
void midi_tx(unsigned char message, unsigned char pitch, unsigned char velocity)
{
 serial.print(message);
 serial.print(pitch);
 serial.print(velocity);
}




the code working grate single sensor, tried make multisensor code, not working...what did wrong?
here's fau;ty code:

code: [select]

int lightpin =0;
int ledpin =9;
int treshold = 400;
int lightlevel = 0;


void setup()
{
 pinmode(ledpin, output);
 serial.begin(9600);
}

void loop()
{
 int lightlevel = analogread(lightpin);
 serial.println(lightlevel);
 if (lightlevel >= treshold){
   switchled();
   delay(500);
 }
}


void switchled(){

 if (digitalread(ledpin) == high){
   do {
     digitalwrite(ledpin,low);
     midi_tx(144,60,127);
     delay(100);
     midi_tx(128,60,127);
     delay(100);      
   }
   while(analogread(lightpin) > treshold);
 }
 else if (digitalread(ledpin) == low){
   do {
     digitalwrite(ledpin,high);
     midi_tx(144,61,127);
     delay(100);
     midi_tx(128,61,127);
     delay(100);
   }
   while(analogread(lightpin) > treshold);
 }
}

// code midi
void midi_tx(unsigned char message, unsigned char pitch, unsigned char velocity)
{
 serial.print(message);
 serial.print(pitch);
 serial.print(velocity);
}


thank much!
davide

the code in both blocks looks same me. did miss something?
