were the output will be a WAV file called test1.wav. There are facilities for transmitting MIDI files within the structure. At present there are no facilities for delivering samples this way, but that will come. This simple strategy allows the local playing of music available anywhere, with a single mouse-click.

This mechanism is also useful for local use, such as on CD-ROM, where large amounts of music can be stored on a 72min CD.

To summarise, we have packaged the system so distribution of sounds via the World-wide Web is made easier, and this is demonstrated also in CD-ROM technology, using a single file format rather than the usual orchestra/score dichotomy. This simple modification to the standard Csound software opens up many possibilities for wider distribution of creative art works.

Performance Issues

The last topic we wish to consider in our search for an effective way to teach music synthesis is a longer term research project which is only just starting. One of the objections to tape music is that it is always the same, and in some sense dead. This can be different in concert conditions when a diffusion system is used, but within the net-based delivery of audio to the home it cannot be assumed that there is such a system, nor the expertise to use it.

The same performance problem has a version in teaching. The computer-composer has to design the instrument and write the score, and what is too easily forgotten is the learning to play, perform and express on this new instrument. Constructing performance details such as phrasing and balance can be a tedious exercise for a student (or indeed an older composer) and could act to deter the use of the technology; for example Richard Dobson11
