Hello Andrew,

If you are familar with the java collections API, you may find the
ArrayList class in LiCK easier to use than ChucK arrays.  A bit more
verbose though.


ArrayList notes;
for (0 => int i; i < 32; i++)
  Note note;
  Math.rand2(440, 880) => note.freq;

// sample notes randomly
while (true)
  notes.sample() $ Note @=> Note note;

// for loop
for (0 => int i; i < notes.size(); i++)
  notes.get(i) $ Note @=> Note note;

// iterator style
notes.iterator() @=> Iterator iterator;
while (iterator.hasNext())
  iterator.next() $ Note @=> Note note;

// functor style
PlayNote playNote;

class PlayNote extends UnaryProcedure
  fun void run(Object value)
    value $ Note @=> Note note;
