Dyskograf 

Interactive sound installation developed by Avoka can let participants create music by marking sequences on a paper disk with a pen, which is then read by the machine - a sort-of Oramics Machine in turntable form:

DYSKOGRAF is a graphic disk reader.  Each disc is created by visitors to the installation by way of felt tip pens provided for their use.  The mechanism then reads the disk, translating the drawing into a musical sequence.

The installation is above all a tool, which allows the creation of musical sequences in an intuitive way.  The notion of a loop, closely linked to electronic music, is represented here by the cycle of the disk.  The disk passes indefinitely in front of a camera fixed onto an arm.  This substitution for the needle converts the drawing into sound by way of a specific application program  (software).  Through this system, the sequential ordering of music is learnt in a playful way, at the same time creating a unique object, souvenir of the musical composition.
