OrchPlay provides access to all individual instrumental tracks of the full orchestra and enable subsets of instruments involved in a particular orchestral effect to be heard in isolation or within the full musical context. This tool provides unprecedented opportunities for scientific research on orchestration perception, for computational modeling of orchestration techniques, and for orchestration pedagogy and performance practice. Any user's instrumental setting related to any section of the score (measure numbers and time-based unit selections) can be saved as a bookmark with individual name, description and relevant score pages for use in the classroom, public presentations or personal enjoyment.
Bookmarks and Bookmarks Lists can also be exported and shared with all other users. Standard stereo files can be imported and any related document can be embedded. The OrchPlay Music Library currently offers a selection of over 100 musical pieces (from short excerpts to full movements) from the symphonic repertoire from late 18th Century to Contemporary. The selection is planned to feature a growing number of complete movement and expand to ca 400 significant orchestral masterworks within a few years. The goal is to provide an international reference database of multichannel orchestral recordings accessible to the widest public possible.
