jm-Etude Problems
Feb 3rd, 2007, 6:21pm  
I am creating a sound project with the jm-Etude library. I installed the library into my folder and imported it into processing but it keeps coming up with the error:

"Semantic Error: No applicable overload was found for a constructor with signature "Etude(Temporary_3999_7365.Score)" in type "jmetude.Etude". Perhaps you wanted the overloaded version "Etude(processing.core.PApplet p);" instead?"

When I use this piece of code:

class Score{

 
void be(){
     
Etude e = new Etude(this);
e.createPart("piano");
e.setPartInstrument("piano", e.PIANO);  
     }

 }

Does anyone know why? I would be really grateful for any help.

because of the way inner classes are handled, you can't use this in that manner. you'll have to pass the PApplet object to your Score constructor, i.e.

Code:

Score s = new Score(this);

class Score() {

  Score(PApplet parent) {
    Etude e = new Etude(parent);
    ... etc

Thanks for the help! It now works but chucks up the error:

"java.lang.NullPointerException
at processing.core.PApplet.registerNoArgs(PApplet.java:737)"

With the piece of code:

Score m = new Score(this);

class Score{


Score(PApplet parent){

Etude e = new Etude(parent);
e.createPhrase("phrase_1");
float[][] notes = {{e.C5,e.Q}, {e.D5,e.Q}, {e.E5, e.Q}};
e.createPhrase("phrase_2", notes);  


}


void setup(){}

 
 void draw(){}
 
 
}

Any idea why?

looks like the Etude instance gets lost on the way. give this a try:

class Score {

Etude e;

Score ( PApplet parent ) {

e = new Etude( parent );

...

I am using colour tracking and jmetude together so that depending on the angle of a line drawn it converts this into sound. But whenever running the program jmetude slows down or even freezes my the video tracking. Is this a common thing? and is it a bad idea to attempt to use this library?

ALSO the library doesn't recognise:

'e.addPhrasePart("melody", "intro_melody");'

any ideas why? Sad
