Connecting the VK-8 to External Devices
About MIDI
MIDI (Musical Instrument Digital Interface) is a worldwide
standard for exchanging music data among electronic
musical instruments and computers. MIDI does not send
audio signals, but instead converts performance data and
commands into digital data for transmission. The digital data
handled by MIDI is collectively referred to as MIDI
messages. Any device with a MIDI connector can be
connected via a MIDI cable to another MIDI device, to allow
data to be exchanged regardless of the manufacturer or
model of the device.

About MIDI Channel
MIDI is able to transmit or receive a large number of
messages over a single cable. In order to do so, it uses a
concept called “channels” (analogous to the channels used in
TV broadcasting), so that MIDI messages are received only
when the channel of the receiving device matches the
channel of the transmitting device.

External MIDI Device

The VK-8 has four parts: the “upper part,” “lower part,” and
“pedal part” of the organ voice, and “other tones.”
When you play a preset sound on the VK-8, you will hear the
sound of the Upper Part. If you connect an external keyboard
or pedal keyboard, you will be able to play the Lower Part or
Pedal Part together with the Upper Part.
The VK-8 has three MIDI connectors.
