Like a very severe tremolo, Skidder “turns your signal 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. Skidder can also sync with your song tempo and can be triggered by MIDI notes.”
Simple, but kinda awesome as well.
