Since the beginning of electroacoustic music at the end of the forties, there has
been a continuous need for new machines. New machines meant and mean
new possibilities and new trends for music. Machines tend to loose interest
once they are mastered or have served several times. However, after a certain
period of time, interest seems to regain on them and new compositions are
done. Where is the interest, what has changed with time? How do mental
structures adapt to new environments?
