Here is an awesome device that requires no input or feedback loop. In fact, if can be used in a feedback loop but it's fairly uninteresting without being processed by anything. By itself, it is sort of similar to the Bit Swash I posted on here a long time ago. You can hear it's flanger-like tendencies in the cycle. It's a droner and doesn't really glitch or sputter. Just long, harsh oscillations that move as fast as you have the speed set. I prefer the speed all the way down. Each toggle combination is a different kind of soaring group of frequencies. When a toggle is flipped, the cycle often starts over and it sounds really cool. Like a super loud, robotic plane taking off.
