Can generate a Sound of Raining and its sequence?

    I don't know if this raining sound in the video is pre-recorded, but I wonder, if it's possible to generate a sound of raining (not a pouring rain) by only using maxmsp. each drop sounds are little bit different each other but sound like raining with combined. and I would like to set each raindrop generates a bang.. (not generated by noise or saw object..)
    also, can I make and control a smooth sequence of start,middle,end of raining? (few drops slowly, many drops growing fast, few drops at the end)
