tempo
Description
Produces metronomic output controllable in beats per minute, and with specifiable whole-note divisions.
Examples
Arguments
tempo [int or float]
The first argument sets an initial tempo, from 5 to 300 beats per minute. If there is no argument, the initial tempo is 120 beats per minute. The second argument is the beat multiplier and is set to
by default. The third argument sets an initial rhythmic value of the output, from a whole note ( ) to a 64th note triplet ( ). If the argument is not present, the initial value is .Attributes

Arguments
In 2nd inlet: The number is stored as the tempo, in beats per minute (quarter notes per minute).
In 3rd inlet: The number is a beat multiplier, which can lengthen the amount of time taken for one beat. It slows the tempo down by a factor. For example, a multiplier of will make tempo send out its output half as fast.
In right inlet: The number is the rhythmic value sent out by tempo, specified as a fraction of a whole note. For example, the number 8 causes tempo to output eighth notes, relative to the specified (quarter note) tempo. The numbers sent out the outlet cycle continuously between 0 and the number 1 less than the rhythmic value. The divisions of a whole note must be between 1 and 96.

Output
int
When tempo is started it outputs numbers in a continuous cycle from 0 to the number 1 less than the specified rhythmic value. The speed at which the numbers are sent out is determined by the tempo (quarter note beats per minute) and the rhythmic value of the output (fraction of a whole note).
