Tap Delay
The Voodu Valve allows you to change the current delay time settings for the Delay 1 and Delay 2 parameters
while you are playing by connecting a momentary footswitch to the rear panel FOOTSWITCH jack. When the
Footswitch function is activated, tapping the footswitch will change the current delay time based on the amount of
time that passes between taps. The Voodu Valve will detect the amount of time between any two taps that are less
than one second apart
(i.e., if more than one second passes after the first tap, two more taps - less than one
second apart - will be required to change the delay time again).
After the Voodu Valve detects the length of time between each tap, it then multiplies or divides that time based
on the type of note stored in each of the DELAY 1 and DELAY 2 parameters of the Footswitch function. The resulting
delay time can be:
• one-fourth of the time between taps (SIXTEEN)
• one-half of the time between taps (EIGHTH)
• two-thirds of the time between taps (TRIPLET)
• equal to the time between taps (QUARTER)
• two times the amount of time between taps (HALF), or
• four times the amount of time between taps (WHOLE)
The maximum delay time the Voodu Valve provides is 1000ms, therefore the Tap Delay feature will default to a
lower parameter value when the time between taps requires a delay time over 1000ms. For example, if the WHOLE
setting is stored for the Delay 1 parameter and the time between taps is 300ms, a delay time of 1200ms would be
required (i.e. 300ms x 4). Because the maximum delay time is 1000ms, the Voodu Valve will default to the next
lower multiplier (HALF) and provide a delay time two-times the delay time detected (600ms). If the delay time was
over 1000ms again, the unit would then provide the QUARTER note equivalent.
NONE can also be selected for the Delay 1 and Delay 2 parameters so that they will not respond to taps on the
footswitch.

Turn the FUNCTION SELECT control to "FOOTSWITCH".
Turn the PARAMETER SELECT control one step clockwise to display the current momen-
tary footswitch "TYPE" (normally open or normally closed).
