Within the framework of Re-Imagine Europe, A4 commissions Jano Doe and Adéla Kudlová to create an audiovisual performance with the Číslizvuk-syntheziser. It premieres at the NEXT festival in 2017. Číslizvuk is the name of the modular synthesizer that was created at the Prague Radio and Television Research Institute in 1977. For the engineer Miroslav Kasper it was the first task after he had finished his studies, without having seen any documentation of other modular synths. The machine was originally to be called Digitsound, but the English version of the name did not go through. In the commissioned festival performance, one of the three existing devices is played by Jano Doe, the music moniker of the curator Katarina Gatialova who has also taken part in the re-acquisition and repair of this machine. The live visual component of the performance is taken care of by the Prague based artist Adéla Kudlová.
