MIDI Pedalboard PK-9
Connecting the PK-9 to an external
MIDI device
You can use your PK-9 as a MIDI controller for a MIDI
tone generator.
1. Make sure that the external MIDI device is
turned off and its volume is minimized.
NOTE
To prevent malfunction and equipment failure, always turn
down the volume, and turn off all the units before making
any connections.
2. Use a MIDI cable (commercially available) to
connect the PK-9’s MIDI OUT socket to the
MIDI IN connector of MIDI external device.
3. Connect the PSB-1U adaptor to the DC IN
socket (page 11).
Once everything is properly connected, be sure to fol-
low the procedure below to turn on their power. If
you turn on equipment in the wrong order, you risk
causing malfunction or equipment failure.
4. Turn on the power of the external MIDI
device and adjust the volume as explained
in the its owner’s manual.
5. Press the PK-9’s [POWER] switch positioned
in the rear panel.
6. Set the PK-9’s MIDI channel (page 15).
7. Set the MIDI channel on the external MIDI
device to match the channel set for the
PK-9.
8. Play the PK-9’s pedalboard.
If the external instrument plays the notes, connec-
tions are complete.
NOTE
This unit is equipped with a protection circuit. A brief inter-
val (a few seconds) after turning the unit on is requested
before it will operate normally.
Using both the PK-9 and a MIDI
keyboard controller
You can also control an external MIDI module using
both a MIDI keyboard and the PK-9.
This allows you to use both your hands and your feet to
control either the same part or two different parts of
the external module.
1. Make sure that the external MIDI device is
turned off and its volume is minimized.
NOTE
To prevent malfunction and equipment failure, always turn
down the volume, and turn off all the units before making
any connections.
2. Use a MIDI cable (commercially available) to
connect the PK-9’s MIDI OUT socket to the
MIDI IN connector of MIDI external device.
Use another MIDI cable to connect the key-
board’s MIDI OUT socket to the PK-9’s MIDI
IN socket.
In this scenario, the messages the PK-9 receives via
its MIDI IN socket are mixed (“merged”) with the
PK-9’s MIDI messages and transmitted via its MIDI
OUT socket to the external MIDI module (“Soft Thru”
function).
NOTE
The exact copy of the MIDI data received via the PK-9’s
MIDI IN socket is also sent out from its MIDI THRU socket.
Though you could also use this connection scenario, be
aware that it only works if your MIDI module has two MIDI
IN sockets. Therefore, the “merge” approach is usually more
practical.
