  Thanks to all.
  I've tried some test with the first version and there is not any
problem, even with thousands of notes:

class Note:
   def __init__(self, pitch, duration):
      self.pitch = pitch
      self.duration = duration
   def change_pitch(factor): pass
   def change_duration(factor): pass


if __name__ ==  '__main__':
    import time
    notes = []
    t1 = time.clock()
    for x in range(10000):
        notes.append(Note(x, x))
    t2 = time.clock()
    print t2 - t1

Pentium 800, 128 Ram, W2K: 0.16 s
Pentium 133, 40 Ram, Linux (woody): 1.67 s

For my purposes, this are acceptable values.

Again, thanks for your advices.
