prototype 1,2011 (2011/2015)
for bowed multitouch-tablet-transducer-cello instrument and percussion

The piece “prototype 1,2011” draws its name from its unfinished, sketch-like nature — a prototype, cobbling together parts towards some incomplete idea, as technology is continuously develops towards some kind of human-computer hybrid life-form. The instrument bodies making up the instrument are dismembered, disembodied and glued back together, some parts remote-controlled, some parts tactilely manipulated. The design of the instrument mirrors an acoustic instrument, and creates sounds based on combinations of gestures typical of traditional string instruments. The sounds of the instrument are half-organic, half-synthetic. The raw noise of bow, usually filtered by the string, is heard directly. Fingers on the glass surface become attack impulses that cause vibration in the acoustic instrument. The finger attacks and bow energy activate the digital sound, which in turn activates the acoustic body — in both cases, the sudden actions are designed to expose characteristics of the system that creates them. Rather than bowing the instrument, sending the bow’s energy into the strings which resonate in the instrument’s wood body, the bow is used to send energy into a digital body which in turn sends its reaction as digital noise into the acoustic instrument via the transducers mounted to the instrument body.

"bowed electronics", 2015 ipad version


A set of transducers are placed on the strings which projects the synthetic sounds into the strings. A bowed contact microphone acts as the main amplitude control, while the iPad controls the parameters for various synthesis processes. Since the microphone and instrument (here a guitar) are on the same table, a feedback loop occurs which is additionally manipulated with filters and delay networks.
