((1)) Patch Work is a lisp-based visual programming environment
for music. Propositions are made in this paper for the extension of
Patch Work visual scheme to full object-oriented programming.
((2)) The PatchWork (Laurson, Duthen, ICMC 1990; Malt, 1993) experience at IRCAM has proven the
great interest shown by composers in visual programming. PatchWork has been
distributed, through the IRCAM user's group, to over a hundred musicians and
researchers in musicology. Many specialized libraries have been written at
IRCAM and elsewhere adressing a wide variety of problems including new
models for rhythm quantification (Assayag & al, ICMC 1994), or musical
constraints propagation schemes (Rueda & al, ICMC 1993). Composers that did
not know a word in computer science have realized in PatchWork visual
programs (patches) of an amazing complexity, due to PatchWork original
mixture of functional programming and graphical data editing.
Thus we have reached the point where we must ask ourselves : what is the threshold of
complexity, that is, when does the musician come and tell us : you guys have to
code in Lisp a new box doing this and that and modelling this musical data
structure, because it is beyond reachability by the mean of visual programming --
and how can that threshold be pushed back ?
