Introduction to the MAQUETTE.

Functions used

MAQUETTE, tempobj and blue and red patches.

Overview

The MAQUETTE is a special object that takes in consideration the time and space dimensions.

In the MAQUETTE's editing window, we can notice x-y axes. The x axis represents time in seconds .

Many objects may be directly placed in a MAQUETTE, like CHORDs, CHORD-SEQs, patches, soundfiles, and even MAQUETTEs themselves. But a special patch may be called inside the MAQUETTE: the tempobj (command-click&drag).

Beside the icons for adding inputs and outputs, the tempobj comes wih two special elements.

A: The self icon represents the slots of the tempobj object. These outputs return valuable information concerning the tempobj status in the MAQUETTE.

B: The tempout output is a special allocation device. The object connected to it will determine the tempobj output and behavior in the MAQUETTE.

In the example above we placed two objects. The first is a CHORD object. The second is a tempobj.

If we double-click on the tempobj we will open its editing window where we can find the same CHORD object connected to tempout. Its behavior inside the MAQUETTE will be the same as the CHORD object, ( i.e it will play the chord). There is a certain advantage in having musical objects inside tempouts objects. This will allow us to use the outputs of self in order to determine or to change the object's position dynamically, or to patch it with another object. (For further information please refer to OpenMusic Reference Guide).

Description

In this introduction to the MAQUETTE we will use tutorial 8 and tutorial 12 patches as temporal objects.

Maquette structure

• Create a MAQUETTE (command-2) or from the File menu 'New'.

• Open the MAQUETTE by double-clicking on its icon.

• Drag and drop tutorial9 and tutorial11. You will notice that once you drag patches in the MAQUETTE they are automatically encapsulated in a tempobj.

• In order to 'play' the musical objects inside these patches, we must connect the CHORD and CHORD-SEQ objects to the tempout output of the temporal patch. For this reason, we must create for each of these patches extra outputs. But before doing so, we must first 'abstract' the blue patches (transform them into red ones). If we don't do so the additional output created will be mirrored in our original patches. To transform our patches into red ones, select the patch and type 'a'.

• Now that our patch is transformed into a red one, open it and create an additional ouput, that you will connect to the first output 'self' of the musical class CHORD.

• Then close the patch and connect its newly created output to tempout.

• Do the same thing with the other tempobj.

• Now you can position the tempobjs in the MAQUETTE in the desired position (e.g tempobj before tempobj1, or vice-versa, or simultaneously,).

• Before 'playing' the MAQUETTE one must always evaluate it using the 'Eval' button of the MAQUETTE's control panel.

• You can also select both tempobjs and type 'm' in order to see the contents of the CHORD-SEQ and CHORD. Each time you evaluate the MAQUETTE you'll notice a different musical output due to the random function included in the tempobj1.
