Thanks for your reply to my message. I may well proceed to develop a
software synthesizer based on SAOLC that can work as a plugin, or I may try
to get an explicit license to do this for Csound.

In any event, anything I have to say about this that is specific to MPEG-4
will now be directed to the appropriate mailing list.
