The basics of using photo resistors to control the signal flow in your music.

Here I show how a simple circuit with a photo resistor interrupts the signal flow of an audio source. The resistor only allows audio to pass through when light hits it. By applying a strobing light source, you can create pulsing signals that you can add effects to, and even use as a noise source for triggering samples.

so cool ideas, and so great music! very very big!

Dude this is probably the coolest thing I’ve ever seen

imagine doing a live set during the 2024 Eclipse and letting the beat distort just as the sun gets blocked out

I’ve just built the exact little circuit that you have, however, it has introduced a lot of noise into the signal. Any idea why that would be?
