TemporalBoxes Interaction : Examples (1)
Here is a series of basic examples showing how the graphic and musical parameters of objects can interact within a maquette. They may give a hint of the principles at stake in the musical exploitation of the maquette’s specific dimensions.
Determining Pitch From “Posy”
The vertical position of a TemporalBox can be converted into a pitch .
Program
The patch shows :
- a temporalbox instance,
- an internal maquette,
- the addbox2maquette function,
- an internal patch that executes the conversion.

-
A Self Input box is connected to om-scale.
-
The “posy” of self is scaled from a value between 0 and 100 to a value between 4000 and 8000 midicents.
-
The resulting value is expressed by a note, and assigned as a musical value to the TemporalBox via the Tempout.
Inside the conversion patch.

TemporalBox Evaluation
Once addbox2maquette is evaluated, the box appears in the maquette. It doesn’t have a musical value at first, but its has a “posy” and an offset. The pitch changes with the vertical position of the TemporalBox, when the maquette or the object is evaluated.
