From the developer:
Grégoire is an application for editing partitions for Gregorian chant.
Program operation is very close to that of a vector drawing package, specific knowledge is not required for using it. Its very intuitive design enables easy access for anyone who is acquainted with computer programs.
In order to make a partition you use the mouse for moving predefined objects like neumes to their right place in a staff.
You may want to check out more software, such as Virtual Guitarist 2, Waves 360 Surround Tools Bundle or VertexDSP vxPlug, which might be similar to Gregoire.
