Troubleshooting
If the PK-7 does not function as you expect, please check
the following points first. If this does not resolve the
problem, contact your dealer or a nearby Roland service
center.
●
The power (indicator) does not come on when I turn
on the power switch.
◆
If the PK-7 is connected to a device that cannot use
the PK cable (such as the VK-8), the supplied AC
adaptor must be used. After connecting the AC
adaptor correctly, turn the power switch on.
●
The power (indicator) does not turn on/off when I
turn the PK-7’s power switch on/off.
◆
The PK-7’s power is switched on/off in tandem
with the VK-88 when it is connected to the VK-88
using the PK cable that is supplied with the VK-
88. Make sure that the VK-88’s power is turned on
and the PK cable is connected correctly.
●
The foot switch, hold pedal, and/or expression
pedal do not operate correctly.
◆
Make sure that the expression pedal cable is
correctly connected to the connector on the upper
part of the PK-7 (p. 7).
◆
If the PK cable is used to connect the PK-7 to the
VK-88
•
Make sure that the cable is connected correctly
(p. 7).
•
Check the settings of the switches or pedals.
Foot switch: VK-88 Owner’s Manual, p. 68 (PK
FOOT L ASSIGN/PK FOOT R ASSIGN)
Hold pedal: VK-88 Owner’s Manual, p. 80
(HOLD PEDAL ASSIGN)
Expression pedal: VK-88 Owner’s Manual,
p. 82 (ORCHESTRAL TONES EXPRESSION)
◆
If a MIDI cable is used to connect the PK-7 to the
VK-8
•
Check that the MIDI cable is connected
correctly (p. 8).
•
If you wish to use the expression pedal to
control the volume of the Other Tones, use a
stereo cable (phone-phone) to connect the PK-
7’s EXPRESSION OUT jack to the VK-8’s
EXPRESSION PEDAL jack, or the PK-7’s
EXPRESSION OUT jack to the VK-8’s
CONTROL PEDAL jack. (VK-8 Owner’s
Manual, p. 40–41)
◆
If MIDI and analog cables are used to connect the
PK-7 to the VK-8
•
Make sure that the polarity of the VK-8’s
CONTROL PEDAL jack is set to “Standard.”
(VK-8 Owner’s Manual, p. 56)
•
Make sure that a function is assigned to the VK-
8’s CONTROL PEDAL jack. (VK-8 Owner’s
Manual, p. 40–41)
•
Use a stereo cable (phone-phone) when
connecting the PK-7’s EXPRESSION OUT jack
to the VK-8’s EXPRESSION PEDAL jack, or the
PK-7’s EXPRESSION OUT jack to the VK-8’s
CONTROL PEDAL jack.
●
Cannot assign a function to the foot switch.
◆
When the PK-7 is connected to the VK-8 without
using analog cables, functions other than Rotary
Slow/Fast (foot pedal L) and Rotary Brake (foot
pedal R) cannot be assigned.
●
MIDI channel can’t be changed.
◆
If a cable is connected to the HOLD OUT jack, the
MIDI channel can’t be changed. If you want to
change the MIDI channel, disconnect the cable
from the HOLD OUT jack (p. 8).
