REBOUND TIME
On a Hammond 25-note pedalboard, when a pedal is pressed,
a contact actuator spring pushes down on a contact at the front
of the pedal key, causing the note to sound. Th
e tension on the
pedals can be adjusted by turning the tension nuts at the back of
each pedal key.
Over time, the pedal tension can loosen, resulting in a pedal note
sounding rapidly and repeatedly when a pedal key is released. Th
is
is sometimes called “rebound.” Th
e XPK-250W Rebound Time
feature allows you to control this eff ect electronically without hav-
ing to change the tension on the pedal springs. If you want to
adjust this feature, do the following:
Press and Hold the top pedal (B) and the pedal corresponding to the value you want
(see the diagram on the left). Th
e LED on the left side of the Expression Pedal will
blink the number of times corresponding to the value you have chosen.
You may select from “1” to “16” repetitions, with each repetition separated by 5.3
millisecond. Th
e default setting is “1” repetitions.
Note: Too long rebound time will cause a delay in the sound.
MIDI CHANNEL
Normally, the XPK-250W Pedalboard transmits MIDI data on
MIDI Channel 3. However, if you need to select a diff erent
MIDI Channel for the Pedalboard, do the following:
Press and HOLD the top “C” pedal key and the pedal corre-
sponding to the MIDI channel you want (see the diagram on
the left). Th
e LED to the left of the Expression Pedal will blink
according to the MIDI Channel you select.
For example, if you select MIDI Channel 7, the LED will blink
7 times.
You may select MIDI Channels “1” through “16.”
LOAD DEFAULT VALUES
To restore the factory default settings of the XPK-250W, do
the following:
Press and Hold the top three pedals (“B
,” “B” and “C”)
and turn the power “ON.” Th
e LED on the left side of the
Expression Pedal will blink three times, indicating that the
XPK-250W factory settings have been restored.
