::vtol:: volnovod

"I’ve came up with the idea of this device during a long flight, when my iPod earbuds (the standard white ones) got caught up yet again. The wires of this manufacturer are covered with special rubber that grants the earbuds a unique feature: they do not fracture or bend; they just intertwine endlessly, which prolongs their lifespan and prevents contact damage. Therefore, in a typical coincidence, my wire intertwined many times and I noticed that it resembled a complex multidimensional wave. The concept of the machine came across my mind at once: a machine that would deliberately intertwine this kind of wire in different ways, then a camera would digitize it and a special algorithm would transform the result in a parametric graph controlling different parameters of sound synthesis.

The device ‘Volnovod’ is a result. I think of this device as a hybrid machine, which combines a kinetic sound sculpture and a unique controller/tool. It bases on the concept of some small phenomenon being adapted, raised and automatized. Thus, a very peculiar for me combination of a tangible wave and depending on it soundwaves worked out.

The device operates in automatic mode, semi-automatic mode or manual mode. Two stepper motors constantly turn and intertwine the wire, moulding different types of waves. Motors operate in accordance with the random numbers-based program and randomly change the direction. Still they rotate within the preset number of steps range to prevent the wire from over-intertwining. The camera shoots a wire in front of a black background, which makes possible to achieve the highest picture contrast. Nine wave pictures are saved. Later they can be updated in automatic mode or refiled manually in semi-automatic mode or manual mode. These nine shots then morph into graphic tables with resolution of 270 x 240 points. The tables are the base to control sound synthesis options. The program can generate parameters in any suitable format: MIDI, OSC, CV. It allows to use it freely as within the system as with external devices. Graphs reading can be written down automatically or manually, with different velocity in many directions. The wave form can also put to use as a harmonic oscillator wave (akin to wavetable synthesis).
