[Orchidea]

Creative computer-assisted orchestration


Orchidea is a framework for static and dynamic computer-assisted orchestration.

It is the new generation of the Orchid* softwares for assisted orchestration, created in the Ircam Music Representation team and is made of several tools, including a standalone application, a Max package and a set of command line tools.

What is computer-assisted orchestration?

Assisted orchestration can be thought of as the process of searching for the best combinations of orchestral sounds to match a target sound under specified metric and constraints. Although a solution to this problem has been a long-standing request from many composers, it remains relatively unexplored because of its high complexity, requiring knowledge and understanding of both mathematical formalization and musical writing.

Max package

To install the Max package, just unzip the downloaded file and copy the orchidea folder inside the Max folder located in your Documents folder. Some tutorials included in the package require the latest version Bach and Dada libraries to function properly, that you can find in the Max package manager.

Standalone version

The standalone version is still in pre-release; you need to download the datasets separately.

Command line tools

Download the command line version if you plan to do batch processing for research purposes; you need to download datasets separately.
