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 con­troled this noise ma­chine to gives me the fre­quen­cy he wants, and my mis­sion is pro­cess that fre­quen­cy to be dif­fer­ent sounds.
I pluged 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.
