Musician Vu Nhat Tan has installed an electric circuit into the mini mixer, within purpose to make different frequencies at the same time. It became a noise machine, can makes some pure analog sounds.
Tan controlled this noise machine to gives me the frequency he wants, and my mission is process that frequency to be different sounds.
I plugged the cable to connect the sendFX gate of that machine with the sampler unit SU200 Yamaha ---> guitare effect Digitech RP3 ---> separate out put. The idea of this experimental piece is likes 2 persons playing on the chess.
