The DD-500's three footswitches can be set up to work in several ways depending on the configuration desired.
To access this setting:
1. Press EDIT.
2. Use the UP/DOWN ARROW buttons to select “SYSTEM” and then press the [EDIT]
button.
3. Use the UP/DOWN ARROW buttons to select “FSW MODE,” and use the [TIME/
VALUE] knob to select the mode.
The Modes available include:
NORMAL - Use the [A] and [B] switches to select patch A or patch B, and use
the [TAP/CTL] switch for tap input.
A/B/C - Use the [TAP/CTL] switch to select patch C. In this case, you would not
be able to use [TAP/CTL] for TAP or CTL functions.
A/B SIMUL - Patches A and B can be used simultaneously. Press the unlit [A] or [B]
switch to make both light.
SW DN/UP - Use the [A] switch to turn delay on/off, and use the [B] switch and
[TAP/CTL] switch to change patches
