Computer music in the service of music therapy: the MIDIGRID and MIDICREATOR systems.

The paper describes the use of the MIDIGRID and MIDICREATOR systems with a range of transducers and interface devices in music therapy. This opens up new possibilities, as well as new challenges in the way in which such technology may be used in therapy. The paper includes a discussion of the role of music therapy, together with some case histories involving the use of these systems.
