Reference

The following MIDI messages are handled with the V-440HD.

• Bank Select and Program Change

These messages are used for switching tones. On the V-440HD, Bank
Select messages are used to select the bus, and Program Change
messages are used to select channels.

• Control Change Messages

These generally transmit information, such as vibrato, hold, and
volume, that enhances the realism of performances. All functions are
organized according to a controller number from 0 to 127, with each
function being assigned its own number. On the V-440HD, these
messages are used with the video faders and knobs.

• System Exclusive Messages

These messages are used for transmitting device-specific settings.

On the V-440HD, these messages are used for transmitting P in P
settings and when setting the Multi Screen outputs.

When System Exclusive messages are exchanged, MIDI
transmissions are distinguished by Device IDs rather than MIDI
channels. When exchanging System Exclusive messages, set the
devices to the same Device ID.

MIDI Implementation Chart

The use of MIDI makes it possible to communicate with a broad
range of electronic musical instruments. However, this does not
mean that all MIDI messages can be exchanged among all devices.
Only those MIDI messages that both of the communicating devices
are designed to understand can be exchanged. The owner’s manual
that comes with a MIDI device includes a MIDI Implementation
Chart (p. 77). Such charts allow you to easily find out which MIDI
messages that device can transmit and receive. When using MIDI
devices, compare the charts for the devices that will be
communicating to check which MIDI messages are compatible.

You can have control of the V-440HD be linked to the performance
of a V-LINK compatible instrument (when V-LINK is on)

What is V-LINK?

V-LINK (

) is a function that allows music and images to be

performed together. By using MIDI to connect two or more V-LINK
compatible devices, you can easily enjoy performing a wide range of
visual effects that are linked to the expressive elements of a music
performance.

For information on switching V-LINK on and off, refer to the
Owner’s Manual for the V-LINK compatible device to be connected
to the V-440HD.

You can confirm the V-LINK MODE status by checking whether or
not the MIDI button is lit. Select “14. MIDI setup”(p. 65) from the
menu and set “MIDI Sw Mode” to “V-Link Indicator“.

To see which functions can be controlled from an external device with
V-LINK, refer to the MIDI Implementation on p. 69 as well as the
MIDI Implementation for the device being connected. The functions
that can be controlled may vary according to the device being
connected and the settings.

MIDI channels

MIDI is able to send information over a single MIDI cable
independently to two or more MIDI devices. This is made
possible by the concept of MIDI channels. You can think of
MIDI channels as being somewhat similar in function to the
channels on a television. By changing the channel of a TV set,
you can view a variety of programs being transmitted by
different broadcast stations. This is because data is received
only from the transmitter whose channel is selected on the
receiver.

In the same way, a MIDI device whose receive channel is set to
[1] will receive only the data being transmitted by another MIDI
device whose transmit channel is also set to [1.]
