Troubleshooting

If the PK-9 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 PK-9 suddenly went off

When 240 minutes have elapsed since you last played
or operated this unit, the power will turn off auto-
matically. (This is the factory setting). If you don’t
need the power to turn off automatically, turn the
“Auto Off” setting “Off.” Refer to page 16.
■

No power

If the PK-9 is supposed to be powered using the
adaptor
Did you press the PK-9’s [POWER] switch (rear
panel)?
→Press the PK-9’s [POWER] switch.
Did you connect the supplied AC adapter?
→Connect the adapter.
If the PK-9 is supposed to be powered via its PK
OUT socket
Did you connect the supplied PK cable to the external
instrument’s PK IN connector and the PK-9’s PK OUT
socket?
→Please see “Connecting the PK-9 to an external
instrument with its PK cable” on p. 11.
Did you switch on the external instrument?
→Switch on the external instrument. The PK-9’s
power is switched on/off in tandem with the
external instrument when it is connected via PK
cable.
■

No sound plays

Does the external instrument’s MIDI channel match
the PK-9’s MIDI channel?
→When connecting to any external MIDI device, you
must match the PK-9’s MIDI channel to the MIDI
channel set on the connected device. See “MIDI
Transmit Channel” on p. 15 for how to set the
PK-9’s transmit channel.
■

Sounds are not playing correctly

Confirm whether or not the Octave function is set
correctly (page 15).
■

The external pedal or footswitch doesn’t oper-

ate correctly

Is the external pedal or footswitch connected cor-
rectly?
→Please check the connection. See “Connecting an
optional external pedal or footswitch to PK-9” on
p. 13.
Are you using an EV-series expression pedal or a
Roland DP-series or BOSS FS-5U footswitch?
→Use only the specified expression pedal (Roland
EV-series, sold separately) or pedal switch (Roland
DP-series, BOSS FS-5U). By connecting any other
expression pedal or footswitch, you risk causing
malfunction and/or damage the unit.
Did you assign a function to “Pedal Assign” parame-
ter that is supported by the receiving device?
→Please see “Pedal Assign” on p. 16 and the owner’s
manual of the external MIDI instrument.
Did you connect the MIDI cable correctly?
→Please see “Connecting the PK-9 to an external
MIDI device” on p. 12.
