Musical Instruments

The core of most of these items are modified circuits from children’s toys. In some cases custom built or found and unmodified circuits from other devices (such as audio amplifiers, timers or regulated power supplies) were added to expand a pieces’ functionality. Some pieces (such as the sequencers) do not incorporate any circuit bending at all and are built entirely from scratch.

I’ve always considered the form and visual presence of a piece to be as important as the functionality. A majority of the time dedicated to building these instruments is spent on designing cohesive, stylized control layouts and/or constructing specialized hardware and housings. I also enjoy adding purely aesthetic embellishments when time or budget allows. This is often done by carving designs into the housings with metal etching tools or by creating images with layers of cut away, colored vinyl.

    I’m just curious as to if you have ever bent a Casio VL-Tone. I’d love to see your work on one! I can’t wait to implement some of your bends on a SK-1!
