The comeback of the optosonic synthesiser.


live performance by noid and klaus filip
bringing the technology of optosonic synthesizers into the era of DIY.

Most traditional synthesisers put a strong emphasis on reproducibility and the stability of pitch. Therefor they need big and complex mechanisms usually realised inside a black box.
For Sonic Luz the priority is a maximum of flexibility and the possibility for haptic interaction on all the parts of the tone production. 
By moving the lamps or the toneweels on the table, or changing the discs, the composition of the sounds can simply be manipulated, quick and intuitively. The machine has no interior that could possibly hidden, everything is laid open for the audience and generates a performative aspect of great beauty.

Optosonics is a forgotten technology that was widely in use to store, transmit or manipulate information in the beginning of the 20th century.
In fact most early synthesizers were based on optical generated sound.
