"It makes a lot more sense if you just try it out and hear what it does. It can sound like a stuttery vocoder or a stuck beat shuffler or many other delightful things."




dfx skidder

"Skidder turns your sound on and off. While that may not sound very rewarding, you have a great deal of control over the rate, pulsewidth, on/off slope, panning width, etc. You can also relinquish some control to randomization."
