  • Sound composition based on an "autonomisation" of the two systems used by Rutz and Pirrò for improvisation.
  • Speakers are located with the panels
  • Each row is one "basic channel" of sound
  • Sounds within each row might be differentiated through filtering
  • Rows alternate between Rutz / Pirrò (even / odd)
  • Rows are "coupled" to their neighbours, with shifting weights between the two directions.
  • If "energy dissipates" from a system, it tries to invert its neighbouring weights, or lift the "amplification"
  • Towards Bürgergasse, there is one channel of microphone (outside esc), providing the second "coupling" for the bottom most row
  • Each row is implemented as a self-contained machine (Raspberry Pi 4, 4 GB, LogiTech 8-channel USB sound card, 4 channel amplifier, 4 speakers, Dynavox PS 138)
  • Each row provides sensing, using capacitive sensing on the screens, which feeds into the respective Pi
  • There might be additional motorisation

colour gels?


  • reflect the even/odd structure of the sound
  • danger of crinkling
  • gels look bad with "open" artificial lighting (must be indirect)
  • alternative: ND (neutral density) filters


four-channels amplifier (and Raspberry Pi on the left). The idea is to create "self-contained" rows in the space, each consisting of one Pi, one audio interface, one amplifier, one set of speakers, one set of sensors.
