Orchidée is software developed by IRCAM as a computer-aided orchestration tool. It is a MATLAB-based application that communicates with traditional computer-aided composition environments through Open Sound Control messages. This means that it can be effectively controlled from programs like Max/MSP or OpenMusic. It was developed by Grégoire Carpentier and Damien Tardieu during their PhDs at IRCAM, with the help and supervision of composer Yan Maresz. A recent example of its use for orchestral composition were in Jonathan Harvey's Speakings, premiered in 2008, in which speech was analyzed and computed to provide orchestral combinations for the composer. Given an input target sound, Orchidée creates a musical score which imitates the sound using a mixture of traditional instruments. It then
