The ORCHESTRA expander is a text pre-processor that filters and “expands” text input files, and makes it possible to:

  • define and use ORCHESTRA classes,
  • “include” files.

The ORCHESTRA expander is updated and is now used for all input and output files, including the concert.XML file. This means that parts of the concert.XML file can now be given as input in the parameter file.

Furthermore the @evaluate: (<expression>) keyword was added to perform calculations during the expansion proces. See the example below for a demonstration of its use.

In the COMPOSER all text editor pages now have the option to show expanded text. To switch between original and expanded text simply click the “Tex view – Expanded view” button.
