I need to make a rain machine that can simulate rain falling on to a table that is about the same size as an A2 piece of paper. anyone know any ways i can do this? I tried using a small water pump pumping water up on top of a piece of aluminium with holes in it but the water falls continuously out of the holes as they are too big. any suggestions?
You can copy the patch from the picture in max/msp, hip~, lop~ and bp~ are high, low and band-pass filters respectively. Try svf~ instead of each of them as a starting point. I’m not sure what slope the simple PD filters are, probably no more that 2-pole, but either way, svf~ will be a good approximation. And osc~ is equivalent to cycle~.
To take it a step further, you could then synthesize the resonant characteristics of the table your rain is falling on with some parallel resonant filters (reson~).
