Reference
The V-440HD can be controlled from an external device using MIDI.
For example, you can use a Roland multitrack recorder to control
video performances that are synchronized to the sounds.
This section explains some basics of MIDI and describes the use of
MIDI messages with the V-440HD.
What is MIDI?
MIDI, an abbreviation for Musical Instrument Digital Interface, is an
international standard created to enable exchange of performance
data among devices. Any MIDI-compatible device can be connected
simply with a MIDI cable, allowing transfer of performance data and
control of device operations and settings.
After switching on the power (when V-LINK is off), MIDI messages
are output from MIDI OUT in response to adjustments with the
corresponding buttons and knobs. In addition, adjustments identical
to those made with the buttons and knobs are made when the
corresponding MIDI messages are received at MIDI IN.
* For more about MIDI messages, refer to the ““MIDI implementation” (p. 69).
M IDI Connectors
The following three types of connectors are used in exchanging
MIDI messages (data handled with MIDI). On the V-440HD, the
MIDI OUT and MIDI THRU are combined in one connector. The
function is switched according to the operation being performed.
MIDI IN: MIDI messages from other MIDI devices are received
here.
MIDI OUT: MIDI messages from the V-440HD are transmitted
from here.
MIDI THRU: MIDI messages received at the MIDI IN connector are
output as is.
Linking Operations Via MIDI
You can use MIDI to link the operation of multiple V-440HDs. To do
so, make the following settings.
• Linking operation of multiple V-440HDs
Select “14. MIDI Setup” (p. 65) from the menu and set “4. MIDI
Out/Thru Switch” to “Thru.”
• Linking operation using “Multi-Screen Output” (p. 44)
For instructions on linking operation of multiple V-440HDs with
the Multi-Screen function, refer to “Multi-Screen Output” (p. 44).
Temporarily Switching Off Linked Operation
You can stop reception of MIDI signals temporarily by pressing the
MIDI button. This stops linked operation via MIDI and enables
independent functioning of one individual V-440HD.
To restore linked operation through MIDI, press the MIDI button
once more so the button is lit.
