“iltur” is a series of musical compositions featuring a novel method of interaction between acoustic and electronic instruments with new musical controllers called Beatbugs. Beatbug players can record live input from acoustic and MIDI instruments and respond by transforming the recorded material in real time, creating motif-and-variation call-and-response routines on the fly. A central computer receives MIDI and audio data from both acoustic and electronic instruments, it computes the improvisation algorithms, and facilitates the interaction among players. The Beatbugs use a piezo electric sensor to capture and trigger musical phrases, two bend sensor antennae for manipulation, a speaker through which the variations are played, and white and colored LEDs for conveying the interaction to players and the audience.



“The implementation and motivation of (“iltur”) is consistent with Mr. Weinberg’s fine reputation. As an artist and scholar, he seems fittingly concerned with issues of accessibility and the transmission of ideas.”

“One of the more well-known musical controllers is the Beatbug, which works best in packs, as Israeli-born Gil Weinberg demonstrated in a new system called ‘iltur’.”

“(A) particularly memorable work was … Gil Weinberg’s iltur 1, which was fundamentally a demonstration of an interesting collaborative technique…”
