video documentation of the electroacoustic synthesizer v e n t o r g a n o
by andreas trobollowitsch.
the ventorgano is an electroacoustic synthesizer that allows its player precise control.
it consists of five resonating bodies shaped like square columns, over which one guitar string each is
strung and made to vibrate by prepared fans. per string there are two fans that turn at differing
speeds; as these speeds shift, micro- rhythmical elements are the result. the speed of each individual
fan can be adjusted progressively, which also changes the overtone spectrum.
