DD-500 Assignable Control Functions

•Hold—The delay’s feedback is held continuously while the switch is pressed.
•Warp—Increases the delay’s feedback and level simultaneously for powerful expressive effects.
•Twist—Adjusts multiple delay parameters with a single press, creating wild sounds similar to twisting the panel knobs in real time.
•Moment—Outputs the delay sound only when you hold down the switch.
•Roll 1/2—Cuts the delay time to 1/2 of the current setting when you hold down the switch.
•Roll 1/4—Cuts the delay time to 1/4 of the current setting when you hold down the switch.
•Roll 1/8—Cuts the delay time to 1/8 of the current setting when you hold down the switch.
•Fade In—Fades in the delay sound.
