Each element in a MusicShape is actually an array of double. To add an element to a MusicShape you can call MusicShape's add() method with code like:
MusicShape myMusicShape = new MusicShape(4); // declare number of dimensions in constructor
double dar[] = { 1.0, 65.0, 120.0, 0.75};
myMusicShape.add( dar );
To save you time, MusicShape has a few conveniently overloaded add() methods
that take variable numbers of parameters. So the above could also be accomplished
this way:
MusicShape myMusicShape = new MusicShape(4); // declare number of dimensions in constructor myMusicShape.add(1.0, 65.0, 120.0, 0.75);MusicShape's add() method supports up to ten parameters. For MusicShapes of more than 10 dimensions, you must use the first technique shown above (ie build an array of double and add() that).
This example creates a MusicShape and performs it with a MidiInstrument. The MusicShape is a simple ascending melody. After a few repeats, it starts self-modifying by scrambling its pitch dimension.
Here is the complete source code for this
example.
And here's the example in action:
