Conclusion We believe that the DISIPLE system illustrates son for multimedia interactive systems the NeXT machine, and multimedia. The experience gained 1 related systems. Although we have concentrated onth techniques can be used in other domains in music and multimedia systems to just a few. References teach music theory, psychoacoi [1] Wessel, David, R. Felciano, A.
