Tap Delay
The MultiValve ™ allows you to change the delay times and/or modulation rates for any given preset while you are
playing two different ways:
1. By tapping the TAP DELAY/RATE button on the front panel of the MultiValve ™ , or
2. By tapping a momentary footswitch connected to the rear panel TAP DELAY/RATE
FOOTSWITCH jack.
3. By using a Rocktron All Access ™ in Remote mode with the MultiValve ™ and tapping
switch #15.
When any "TIME" parameter within a given preset is set to ½, ¼, TRIPLET, 8TH, 16TH or 32ND NOTE, tapping the
footswitch or the front panel TAP DELAY/RATE button two times will change the current delay time and/or modulation
rate based on the amount of time that passes between taps. The MultiValve
™ 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 additional
taps - less than one second apart - will be required to change the delay time again).
After the MultiValve ™ detects the length of time between each tap, it then multiplies or divides that time based on
the type of note stored for the TIME parameter(s) of the preset. The resulting delay time can be:
• one-eighth of the time between taps (32ND)
• one-fourth of the time between taps (16TH)
• one-half of the time between taps (8TH)
• two-thirds of the time between taps (TRIPLET)
• equal to the time between taps (¼), or
• two times the amount of time between taps (½)
The maximum delay time the MultiValve ™ provides is 1000ms, therefore the Tap Delay feature will automatically
default to a lower "TIME" parameter value when the time between taps requires a delay time over 1000ms. For example,
if the HALF setting is stored for the TIME 1 parameter and the time between taps is 600ms, a delay time of 1200ms
would be required (i.e. 600ms x 2). Because the maximum delay time is 1000ms, the MultiValve
™ will default to the next
lower multiplier (¼) and provide a delay time equal to the delay time detected (600ms).
"NONE" can also be selected for the TIME parameter(s) so that they will not respond to taps from the footswitch or
front panel TAP DELAY/RATE button.
Operating the MultiValve ™
Note 1: If delay times for each preset are selected via the Tap Delay feature (instead of manu-
ally setting the parameters), the flashing front panel tap delay rate L.E.D. will accu-
rately reflect the tapped value that was stored in each preset when it is recalled.
However, the MultiValve
™ must be displaying either a function heading or a param-
eter to store the flashing tap delay rate (i.e., not while displaying a preset title). If a
preset title is displayed when the STORE button is pressed, only the Power On preset
is stored (see page 63).
Note 2: If a footswitch is connected to the rear panel Tap Delay/Rate FOOTSWITCH jack when
the unit is powered up, the MultiValve
™ will automatically determine the type of
footswitch connected (i.e. normally open, normally closed, etc.). However, the footswitch
must already be connected when the unit is turned on.
