Relationship with the Csound .orc and .sco files

Csound divides the process of sound generation in two files: the orchestra file (ending with ".orc") and the score file (ending with ".sco", see the Csound chapter). However, in OpenMusic there is no clear separation between the two files; all the sound process lies within the patch. The example below systematizes the data flow and the relationship with the Csound .orc and .sco files.

This example displays a simple way to convert a Csound score to be used by the OMChroma add-1 class. All the given data are in the TextFile box and OpenMusic deals only with arranging them according to the needs of the matrix.

Note: OMChroma doesn't need the number of instrument statement (the first data of the each line), as it is automatically computed.

Open the corresponding ".orc" and ".sco" files (in the outfiles folder) to take a look at the Csound data generated by OMChroma.

This example is quite developed and all the data are randomly generated by OpenMusic. With respect to the previous example, OpenMusic is used here for what it actually is.

The result of the previous tutorial could be simply obtained in Csound in the traditional way (two text-files). The result of this would be much more difficult to realize directly in Csound.
