Hexagon Eye


Hexagon Eye was produced for a keyboardist from a live band looking for new timbres. It was build by circuit bending a FM syntesizer, in this case the Yamaha PSS-270. Chorus speed, depth, and morphback controls have been fitted. Morphback adjusts the chorus feedback and changes the timbre of the chorus signal simultaneously. An overdrive control is also provided. The sustwist control emphasizes the decay tails of sounds and brings out higher harmonics. An octave drop switch pitches notes down. The randomize switch produces new timbres when active during a patch change. When in use, the keys will play shifting sounds. All controls are fitted into a side cart to allow plenty of room and easy identification for live use. The side cart panel was produced using carbon transfers and acrylic paints.
