Today’s CatSynth video features our very own Big Merp. I was trying out an old photo theremin that I bought years ago, and decided to try playing it in front of Big Merp. Hilarity ensued. Definitely watch the video all the way to the end – the look on his face is priceless.
The photo theremin consists of a simple analog oscillator that uses a light-sensitive resistor (i.e.,a photocell) to control the frequency. So you can move your hand or other objects around it to change the light and thus change the pitch. This one also as an LFO for added sonic variety, and came in a really cool translucent blue case.
