Ululatron

"This is my modification of a Yamaha PSS-50 keyboard. It uses 6 555 times and vactrols to trigger the keys. Rate is controller via potentiometer and note is controlled with 5 rotary switches and a dpdt switch (there were two notes left over). I called it the "ululatron" because it goes into and out of patterns like a pendulums swinging at different rates. There are no effects on the sound. What you hear is the very first thing I did--I'm sure with some more practice it can sound better. And some reverb and delay of course ;-)"
