CoyuyoC it's an analog drone synth based on the legendary 555 chip. Two triangular oscillators (for more pleasure), promiscuously exciting each other. It has patcheable in-out connections, light sensor, nice wing potentiometer knobs and voltage control INput.
Coyuyo it's the name that takes the Quesada Gigas (Giant Cicada) here in the north of Argentina. The coyuyo, spreaded all over the American continent (from Texas to Santiago del Estero) makes a loud sound that sometimes makes it impossible to take a nap in the warm summer siestas.The coyuyo has two resonant membranes which it uses to make the sound. Mimetically CoyuyoC it has two oscillators, one LFO and one VCO which can be controlled independently (by two nice wing-knobs) or it could be connected to each other through a mini switch control station. All connections could be by-passed through a light sensor. Working independently the oscillators go from beat to tones, getting interesting when the frequencies are near ea
