Agenda

Day 17 is music presentations. If you did not present your visual art project, then you will be presenting your music project.

Get ready

Extremely important: I need to have your composition in a form that is ready to play before class starts. Here are your options.

It is your responsibility to make sure that your composition is ready to play when your presentation starts. I will be happy to assist you in getting things set up, but you need to see me before presentation day.

Option 1

Save your composition as a WAV file. This is the best and most straightforward option. Depending on which lab you used as the starting point for your program, you will see a line of code defining a variable called fws. It will look like one of the following:

FunWithSound fws = new FunWithSound(this); // first possibility

MyFWS fws = new MyFWS(this); // second possibility

If you see the first possibility, add the following code to your program, just above the line that defines fws:

class MyFWS extends FunWithSound {
  MyFWS(PApplet parent) {
    super(parent);
  }
  
  protected Player createPlayer() {
    Player player = super.createPlayer();
    registerCustomInstruments(player);
    return player;
  }

  public void saveWaveFile(MyComp c, String fileName) {
    Player player = createPlayer();
    player.setComposition(c.getComposition());
    try {
      player.setStartDelayUs(50000L);
      player.setIdleWaitUs(2000000L);
      player.saveWaveFile(fileName);
    } catch (Exception e) {
      println("Couldn't save wave file: " + e.toString());
    }
  }
}

Then, change the line defining fws so that it looks like the second possibility shown above.

Next, find the mouseClicked method. Change it so that it looks like this:

void mouseClicked() {
  //fws.play(c);
  fws.saveWaveFile(c, "H:/mycomposition.wav");
}

You should change H:/mycomposition.wav to a filename that is appropriate for your composition, and if you are running on your computer rather than a lab computer, you will probably want to use a drive other than H:.

Once your program has the required code, run the program, and when you click in the window, the program will save a WAV file rather than playing using the speakers or headphones. Just copy this file onto your flash drive, and you are set.

Option 2

Post your composition using SoundCloud. To do this, save your composition as a WAV file (as described above), upload it to SoundCloud (you’ll need an account), and then save the URL.

This is also an excellent option. SoundCloud is a great way to share your music via the web.

If you choose this option, you don’t need to bring anything to class with you.

Option 3

Play your composition using Processing.
