# The first patch prints "hello world" to the display.
# The second patch applies reverberation to the incoming signal from channel 1, then emits it on channels 1 and 2.
# The last, more complex patch filters white noise at 9000&nbsp;[[Hertz|Hz]] (with a Q of 20), then fades it in and out each second over the course of a half second. In Pd, time is measured in milliseconds, thus the '1000' is one second and the '500' is a half second.
