Some interesting things I found on May 16th, 2008:
# Speaker Synth – A five-speaker array with no external audio input, created by Lesley Flanigan. The only components in the system are the instrument's speakers, piezoelectric microphones, amplifying circuits, and the hands of the performer.
From the project page:
Speaker Synth is played by positioning individual piezo microphones with their corresponding speakers and manipulating their associated on/off and volume controls to induce a variation of feedback effects. During the performance, samples from both Speaker Synth and a vocalist are captured and sequenced to build a dense sonic pallet of rhythms and melodies. The performance explores music making through structuring noise, highlighting relationships between analog and digital sound synthesis and between human voice and the voice of an instrument.
Check Lesley’s website for audio and video performances and more cool projects.
# Tonefloat – A bit of a mutant mobile milkbottle xylophone. Each bottle has a small electrical hammer behind it, which is 'played' by a midi keyboard or drum machine, and a few strings of wire 'n chips.
# Plague Bearer – designed to infect, corrupt and pervert a signal beyond recognition. It contains four Voltage-Controlled Resonant Bandpass filters that were designed with the goals of maximum signal alteration and maximum parameter controllability.
# Steppers – Steppers were designed to get kids up on their feet, moving, and playing with sound and music. An external sensor sandal is worn over a child’s shoes, noting each footstep, and, in real time, playing back sound effects/music to compliment their movement.
# MIDI Glockenspiel – Using an Arduino make a computer controller MIDI Glockenspiel.
# Mozart from Scrap-Made Mechanical Glockenspiel – A weight-driven automatic glockenspiel made from assorted recovered materials.
# Toriton plus prototype: first look – A more complex version of the Toriton musical instrument. It involves using five lasers instead of just the one.
