Hi, tao (physical modeling synth, see http://web.ukonline.co.uk/taosynth/) is still an unique program. Unfortunately it does not compile out of the box anymore.Probably compilers nowadays are a bit more rigorous in handling small syntax errors. Appended are the very little changes I needed to put in the code before I succeded compiling. Although these changes are really tiny, for unexperienced yacc etc. programmers (like me ;-) it may take ages the locate them.
