Before You Start Using BK-9
22
The BK-9 MIDI THRU socket exactly duplicates whatever data is being
received at the BK-9 MIDI IN socket. It is used to connect to the MIDI IN of
another device.
MIDI channels
MIDI provides sixteen channels, numbered 1~16. Even if two MIDI devices
are connected, you won’t be able to select or play sounds on the other
device unless both devices are set to the same MIDI channel. For more
details see “MIDI” (p. 151).
The BK-9 is capable to transmit and receive on all channels, 1~16.
NOTE
Before making connections with other devices, you must turn
down the volume of all devices and turn o the power to avoid
malfunctions or speaker damage.

expression pedal (Roland EV-5) to control
dierent functions and eects.
NOTE
If you connect a Pedal Switch (e.g. DP2),
to set the function that you want to
assign see “If You Connect a Pedal Switch

Connecting a MIDI Device
The BK-9 can transmit and receive performance data when
connected to an external MIDI device, which enables the two
devices to control each other’s performance.
Connection example
If you use a MIDI cable (commercially available) to connect this
unit’s MIDI OUT connector to the MIDI IN connector of your
external MIDI sound module, you’ll be able to produce sound on
the external MIDI sound module by playing this unit’s keyboard. As
necessary, set the external MIDI sound module’s receive channel to
match this unit’s MIDI transmit channel.
What is MIDI?
MIDI, short for “Musical Instrument Digital Interface,” was developed
as a universal standard for the exchange of performance data
among electronic musical instruments and computers.
The BK-9 is equipped with MIDI connectors to let it exchange
performance data with external devices. These connectors can be
used to connect the unit to an external device for even greater
versatility.
