It seemed to be a direct result of the “Adobe Make Some Noise” campaign:

Although the results were not what was expected originally, they are still very useful. This post from the previous website sums it , and points to some other useful links:

Recently Matti posted about the excellent Popforge library, developed by the same people involved in the “Make some noise” campaign and Hobnox:

Popforge is very powerful, but the learning curve can be a bit high. Some simpler to implement alternatives could be:
