In this performance I am using the Guzheng, a Chinese Zither, with a specially constructed audio processing hardware. The instrument is used with a newly developed alternate tuning and novel playing techniques. The core of this instrument consists of an analog microphone preamplifier with filter, constructed by me plus a digital sound processor on a single board computer (Raspberry Pi) running Pure Data. They all form the amplified and filtered Guzheng signal which is processed through granular synthesis, frequency modulation and amplitude modulation.
