there are many example clients in the JACK source code's
including, as luck would have it, jack_sine, which generates a sine
wave (based on MIDI input) and even simpler, jack_metro which outputs
a beep every 1/Nth of a second.
this list and google contain a wealth of information on JACK
programming, including at least one other thread on this same topic
recently that had some highly relevant links.
you are encouraged to explore the existing examples, tutorials and
other resources available online before asking people to explain it
all one more time. if you have questions once you've started with JACK
because some things are not clear, then please ask away.
