Phonogene producing a lots of bleeps
The Phonogene consist of a round piece of plastic with inside four or six play-back heads from a tape-recorder. The four heads are conected in series with each other. This means that they are not four individual heads anymore but actualy they are one big play-back head. Take a piece of tape carrying sound-information. Let this tape run over one quarter of the circle of the Phonogene (from A to B). When the Phonogene turns counter-clock-wise head nr 1 will “read” the tape in between A and B. When head nr 1 is about to pass B, then nr 2 will just start reading from point A. This results in looping a very short piece of sound. The pitch of the sound is determent by the RPM of the Phonogene. When the tape slowly moves from A in the direction of B, the Phonogene will time-stretch the sound.
