The Profile provides a comprehensive yet concise system of articulation mapping that includes a wide palette of  articulation types and supports articulation equivalence across eight instrument categories. 

The Profile was designed to offer articulation equivalence — a system of articulation mapping that allows a  passage articulated for one instrument to be copied to another track and played back with an equivalent or  analogous articulation, regardless of the target instrument type. 

When implemented by sample library developers, the Profile will greatly aid composers in highly significant ways. 

First, it will simplify the process of substituting or layering sounds from the same or different sample libraries;  Second, it will allow composers to quickly audition and orchestrate unison passages by copying an articulated part to other tracks and hear them to play back with equivalent or analogous articulations.
