Real-time/performed electroacoustic music is currently facing a serious sustainability problem. Although historically its production is very recent, several technological revolutions have gone by in the meantime. Most of these works can hardly be performed because the technology involved has gone lost since the first realization, and no long-standing notational precaution was ever taken. This paper (first published in 2005 and translated in Italian for the first time) presents some typical case studies and introduces some techniques that might lead to a partial — when not completely adequate — solution to the sustainability problem.
