Most of the instruments in my collection of circuit bent projects are incantors (or I'd call them incantors, anyway).
There are only a few aleatrons. Both keyboards shown on this page are examples of my more successful attempts. Below
is a keyboard with an output jack, along with two body contacts consisting of iron drawer pull knobs. The keyboard
at the top of this page resembles the second one but has only one body contact. Actually, the jack itself
can serve as a body contact. Touching the jack and knobs of each of these keyboards results in warping of the demo tunes.
In the first keyboard, the keys themselves were shorted out. Fortunately, this did not occur in the second keyboard.
At the same time, there is no distortion when the keys themselves are played individually. I may be missing something in terms
of possible variation in sound here but that's okay.
