This project titled ‘Oversetter’ was a live performance of digitally controlled grand organ, at the Melbourne Town Hall. The project was inspired by the ‘talking piano’ which uses Fast Fourier Transforms (FFT) to emulate the sound of human speech using only an acoustic piano. FFT was used to make the grand organ reproduce the sound of a digital input signal, which was improvised in real-time using a hardware modular audio system. ‘Oversetter’ aims to reimagine the connection between performer and instrument. The piece draws conceptual parallels to the ‘Medium is the Message’ notion, demonstrating that the interface to the instrument (in the case of the organ - a standard western keyboard layout) informs the music which is produced. By altering the system the performer uses to interact with the instrument, novel musics can be produced.
