Owner’s Manual
Thank you, and congratulations on your choice of the Roland PK-25A Pedal Keyboard.
In addition to the pedal keyboard, which greatly enhances enjoyment in playing the
organ, the PK-25A MIDI pedal keyboard unit also features an expression pedal that
lends precise and dynamic volume expression to performances, a foot switch that en-
ables pedal control over a variety of Roland VK-88/VK-8 combo organ functions, and
a hold pedal for sustaining notes.
Before using this unit,
carefully read the sections
entitled: “USING THE UNIT
SAFELY” (p. 2, 3) and
“Important Notes” (p. 4).
These sections provide
important information
concerning the proper
operation of the unit.
Features
Additionally, in order to feel
assured that you have gained
a good grasp of every feature
provided by your new unit,
this Owner’s Manual should
be read in its entirety. The
manual should be saved and
kept on hand as a convenient
reference.
● Twenty five-note pedal keyboard and removable expression pedal
The PK-25A features a twenty five-note pedal keyboard for maximum enjoyment of
organ playing. The built-in expression pedal can be removed from the pedal keyboard
unit to make the unit more compact for transportation.
● Foot switches for controlling the VK-88/VK-8
Two foot switches are built into the expression pedal. When the PK-25A is connected
to a Roland VK-88 or VK-8 combo organ, you can then switch settings of the Roland
VK-88 or VK-8 as you perform without removing your foot from the expression pedal
or your hands from the keyboard.
● Hold pedal
A Hold pedal is provided. You can easily operate for additional expressive
possibilities when playing sustain-type sounds.
● Single-cable connection to the VK-88
When connecting the PK-25A to the VK-88, the PK cable is the only connection
required–no need for MIDI cables, analog cables, or an AC adaptor. This makes setup
quick and easy.
● Switching MIDI Channels and Octave Shift
The PK-25A also features a MIDI channel switching knob that allows you to match the
MIDI channel settings with other equipment when the PK-25A is connected to an
external MIDI device other than a Roland combo organ (VK Series). Furthermore, you
can use Octave Shift to change the pitch in octave increments.

Important Notes
In addition to the items listed under “USING THE UNIT SAFELY” on page 2 and 3, please read and observe the following:
360
Power Supply
• Depending on the material and temperature of the surface
on which you place the unit, its rubber feet may discolor
or mar the surface.
You can place a piece of felt or cloth under the rubber feet
to prevent this from happening. If you do so, please make
sure that the unit will not slip or move accidentally.
301
• Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled by
an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical
appliance is used, power supply noise may cause this unit
to malfunction. If it is not practical to use a separate
electrical outlet, connect a power supply noise filter
between this unit and the electrical outlet.
Maintenance
401b
• To clean the unit, use a dry, soft cloth; or one that is
302
slightly dampened. Try to wipe the entire surface using an
equal amount of strength, moving the cloth along with the
grain of the wood. Rubbing too hard in the same area can
damage the finish.
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
307

and connectors. Rough handling can lead to malfunctions.
352b
556
• Noise may be produced if wireless communications
• When connecting / disconnecting all cables, grasp the
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initi-
ating a call, or while conversing. Should you experience
such problems, you should relocate such wireless devices
so they are at a greater distance from this unit, or switch
them off.
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
558b
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels (especially when it is late at
night).
354b
• Do not expose the unit to direct sunlight, place it near
559a
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Also, do not allow lighting devices that normally are used
while their light source is very close to the unit (such as a
piano light), or powerful spotlights to shine upon the
same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
355b
• When moved from one location to another where the
temperature and/or humidity is very different, water
droplets (condensation) may form inside the unit. Damage
or malfunction may result if you attempt to use the unit in
this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation
has completely evaporated.
356
• Do not allow rubber, vinyl, or similar materials to remain
on the unit for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
358
• Do not allow objects to remain on top of the keyboard or
pedal board. This can be the cause of malfunction, such as
keys ceasing to produce sound.
359
• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.
