Hello, it's me again...
I'm trying to figure out a way to use a sinewave (sine wave because I need to change the frequency by pressure sensors connected to an arduino board) but don't want it to sound like a Sine Wave. I want to add a different wave to make it sound like violins e.g. Just like an sythethizer works with midi data. Is there a software solution? Can I just add something in my processing code?

Thanks in advance, maybe someone has an idea how i can fix that problem or knows where I can get specific information.


void setup()
{
 size(512, 200, P3D);

 frameRate(200);
 myport = new Serial(this, Serial.list()[1], 9600);

 minim = new Minim(this);
 // get a line out from Minim, default bufferSize is 1024, default sample rate is 44100, bit depth is 16
 out = minim.getLineOut(Minim.STEREO);

// create a sine wave Oscillator, set to 440 Hz, at 0.5 amplitude, sample rate from line out
 sine1 = new SineWave(440, 0.5, out.sampleRate());
 sine2 = new SineWave(440, 0.5, out.sampleRate());
 sine3 = new SineWave(440, 0.5, out.sampleRate());
 sine4 = new SineWave(440, 0.5, out.sampleRate());

sine1.portamento(200);
 sine2.portamento(200);
 sine3.portamento(200);
 sine4.portamento(200);
 // add the oscillator to the line out
 out.addSignal(sine1);
 out.addSignal(sine2);
 out.addSignal(sine3);
 out.addSignal(sine4);
 
 int [] Sensorliste={ vala, valb, valc, vald  };

   float freq1 = map(Sensorliste[0], 0, 1023, 1500, 60);   // Sensorliste ist der array in den ich die vier verschiedenen Werte der Sensoren einspeise
   sine1.setFreq(freq1);
   float freq2 = map(Sensorliste[1], 0, 1023, 1500, 60);
   sine2.setFreq(freq2);
   float freq3 = map(Sensorliste[2], 0, 1023, 1500, 60);
   sine3.setFreq(freq3);

   sine4.setFreq(freq4);
   
// Pan = Ausrichtung: Since Oscillators are MONO signals,
//you can set a pan value for them. This is where “in space” the signal will
// sound between two speakers. -1 is “hard left”, 1 is “hard right”, and 0 is “center”.  
   sine1.setPan(1);
   sine2.setPan(1);

   sine4.setPan(-1);

   for(int i = 0; i < out.bufferSize() - 1; i++)
   {
     float x1 = map(i, 0, out.bufferSize(), 0, width);
     float x2 = map(i+1, 0, out.bufferSize(), 0, width);
     line(x1, 50 + out.left.get(i)*50, x2, 50 + out.left.get(i+1)*50);
     line(x1, 150 + out.right.get(i)*50, x2, 150 + out.right.get(i+1)*50);
