I realise that the original thread may have been more of a focus on Kernel level audio software, rather then user space audio software,

however the old school clunky XForms UI were classic from back in those days. Found some screen shots of the dynamic audio software : https://web.archive.org/web/20001028203345/http://www.cse.unsw.edu.au/~flat…
