A recent release with music by Austrian composer Gerhard Winkler (b. 1959) contains recordings of three pieces for instruments and "interactive live electronics," and an earlier, purely instrumental quintet entitled Zwischenwelten. Mr. Winkler, who has worked extensively in the experimental studio of the Heinrich-Strobel-Foundation in Freiburg, at the Zentrum fur Kunst und Medientechnologie (ZKM) in Karlsruhe, and at the Institut de Recherche et Coordination Acoustique/ Musique (IRCAM) in Paris, is currently lecturer for Multimedia Art in Salzburg and one of the pioneers of real-time interactive composition in Europe.

The three pieces involving electronics, Les chambres separees (1995), KOMA (1996), and entrop (1998), form a trilogy in which the computer's function is not only to transform sounds live, but extends to shaping the formal procedures of each individual performance to a significant degree. The musicians find themselves in a complex computer-controlled environment in which the written score has been replaced with a virtual score generated live and relayed to the players through laptop screens. The interaction between the musicians and this set-up entails, according to the composer:

 
   influencing the computer environment, which reacts in a complex and 
   non-linear way according to the inner system-attributes of the chosen 
   simulation-program, thus forcing the musicians to "live" with the (partly 
   unforseeable) results of their actions: in regard to sound in the live 
   electronics, in regard to notation with the score or the playing 
   instructions projected on the screens in front of each musician. Thus a 
   non-linear feedback cycle is created; the work tends toward musical 
   self-organization.
