Rocktron Xpression - Manual (Page 53)

Tap Delay
The Xpression 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 Xpression,
or
2. By using a Rocktron All Access ™ or MIDI Mate ™ with the Xpression (con-
sult the All Access or MIDI Mate manual for details on this operation)
When any "TIME" parameter within a given preset is set to ½, ¼, TRIPLET, 8TH, 16TH or 32ND
NOTE, tapping the assigned 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
Xpression
™ 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 Xpression ™ 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 Xpression ™ 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 Xpression
™ 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 Xpression ™
Note: If delay times for each preset are selected via the Tap Delay feature (instead of
manually setting the parameters), the flashing front panel tap delay rate L.E.D.
will accurately reflect the tapped value that was stored in each preset when it is
recalled. However, the Xpression
™ must be displaying either a function heading
or a parameter 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).
