Batuhan Bozkurt's Circuli – A Generative Ambient Sound Instrument


Circuli is a generative musical instrument conceptualized and developed by Batuhan Bozkurt.
  • Circles grow at a constant rate.
  • No two circle can overlap.
  • Bigger circle pushes and shrinks smaller circle when in contact.
  • A circle “pops” and makes a sound when its boundary intersects with the center of another circle.
  • The pitch of the sound is determined by the position of the circle on the background. Bigger the hole, higher the pitch.
  • The envelope of the produced sound is determined by a number of parameters including final circle size and time of interaction between two involved circles.

Batuhan Bozkurt's Otomata – Online Generative Music Instrument


Otomata is a generative sequencer. Each alive cell has 4 states: Up, right, down, left. at each cycle, the cells move themselves in the direction of their internal states. If any cell encounters a wall, it triggers a pitched sound whose frequency is determined by the xy position of collision, and the cell reverses its direction. If a cell encounters another cell on its way, it turns itself clockwise.
