The object loadbang sends a bang when a patcher is opened. This object is very useful if you want to automate the start of some objects or messages in your patch. In this example, the movie starts automatically by sending loadbang to read the movie file and the toggle when the patch is loaded. 

Sixteen Harmonics

This example plays the first sixteen harmonics based on a fundamental frequency where the rate at which each harmonic play is period / # of harmonic. For example, with a period of 10000 ms—meaning the fundamental plays every 10000 ms—the 4th harmonic will be heard every 10000/4 ms, or 2500 ms.

Converting notes per second to ms and using the Tempo object

This example shows how to convert a value expressing “notes per second” into "milliseconds per note", which is a more useful value for the metro object.  The right side of the patch shows how to use the tempo object to specify tempo in bpm, and to specify the division of the whole note at which to output numbers indicating which division of the measure it's on.
