Hej,

I started programming couple weeks ago and getting really into it. But for a few days now I ve been trying  to figure out a way to control the frequency of a soundfile by analog input of pressure sensors. I'm using arduino and processing. (My soundfile is not a regular sine/saw wave, but an existing peace of sound which Iwant to loop the whole time)
I'm building on this example code on minim, but simply exchanging the sine wave with a Snippet just won't work... Probably its a typical beginner's question... but if anyone would care to answer I'd be soooo happy to hear from anyone!

import ddf.minim.*;
import ddf.minim.signals.*;

Minim minim;
AudioOutput out;
SineWave sine;

void setup()
{
 size(512, 200, P3D);

 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
 sine = new SineWave(440, 0.5, out.sampleRate());
 // set the portamento speed on the oscillator to 200 milliseconds
 sine.portamento(200);
 // add the oscillator to the line out
 out.addSignal(sine);
}

void draw()
{
 background(0);
 stroke(255);
 // draw the waveforms
 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);
 }
}

void mouseMoved()
{
 // with portamento on the frequency will change smoothly
 float freq = map(mouseY, 0, height, 1500, 60);
 sine.setFreq(freq);
 // pan always changes smoothly to avoid crackles getting into the signal
 // note that we could call setPan on out, instead of on sine
 // this would sound the same, but the waveforms in out would not reflect the panning
 float pan = map(mouseX, 0, width, -1, 1);
 sine.setPan(pan);
}

void stop()
{
 out.close();
 minim.stop();

 super.stop();
}

sounds definitly like an interesting option, which totally got out of my sight. Thanks!
