The tops sheets are cut in different materials : zinc, steel, expanded cardboard, wood, plexiglass. They're attached with magnets when needed to a veneered resonance board. Each sheet has a unique resonant sound. Attached to it are a contact microphone and exciter speaker looping through a sound card and the daisy seed for effects, then finally in a small amp for the exciter. No additional speakers, the sound is both created and emitted from the sheet.
A custom Arduino code controls each of the 8 knobs, with Delay, Compressor, Filter and chorus like effects.
The output from the daisy is sent to a computer with a touch designer to control the live Particle Cloud in the background, inspired from cymatics and Chladni sand research.
