Example 2 : Defining Temporal Relations Between TemporalBoxes

Applying the Values of a TemporalBox to Other TemporalBoxes

The values of the Self Input Box can be used for defining temporal relations with other TemporalBoxes, via connections between functional inputs and outputs.

Building a Sequence of TemporalBoxes

The chord of TemporalBox #1 is a reservoir for isolated notes that will occur successively in the maquette.

  1. We have programmed the TemporalBoxes so that the initial chord provides one random note to each of TemporalBoxes #2; 3; and 4.

  2. The offset of each TemporalBox is determined by the offset and duration of the preceding box , so that boxes follow each other.

Inside TemporalBox #1

The internal program of the first TemporalBox determines some characteristics of the other TemporalBox.

Inside TemporalBox #1 : using the "pattern-chord"'s data.
Inside TemporalBox #1 : using the "pattern-chord"'s data.
  • The initial chord lasts 3 seconds. It is connected to the Tempout of TemporalBox #1, and represents its musical value.
  • Permut-random performs a random permutation of the chord's pitches. The three first pitches of this permutation are returned by nth-first to the first output of TemporalBox #1.
  • On the other hand, the offset of the TemporalBox returned by the Self Input Box, is added with the chord's duration .
  • The result is returned to the second output of the TemporalBox.

TemporalBoxes Interaction

The random pitches – output #1 – are returned to all the other TemporalBoxes. The ending time of the box – output #2 – is returned to the next TemporalBox.

Inside TemporalBox #2
  1. The three random pitches are returned by the first input of TemporalBox #2 to the first function.

    First picks the first note and returns it to the note box. This note is also given a duration.

  2. The note is connected to the Tempout and becomes the musical value of the TemporalBox.

  3. The temporal position of TemporalBox #1, is returned to the "offset" input of slots, which defines the offset of TemporalBox #2.

  4. The offset of TemporalBox #2 is added to the duration of the note, and the result is returned to the output of TemporalBox #2.

  5. The value of the output ending of the box – is returned to the next TemporalBox, which contains the same program.

About Last TemporalBox

Note that the last TemporalBox has nor output, neither om+ function, but a sequence function. The box has nothing to return to another box. The sequence function allows to evaluate slots before evaluating the TemporalBox, so that its offset is correct.
