Audio to a Computer
NOTE
For the video and audio signals from the VR-3EX to be viewed
and heard correctly on the computer, software that supports
USB video class and USB audio class must be installed and set
up on the computer.
1.
Follow the procedure in “Making the Connection to
a Computer” (p. 16) to connect the VR-3EX and a
computer using a USB cable.
2.
Put the VR-3EX in a state capable of outputting video or
audio.
Operate the VR-3EX to get it ready to output video or audio to the
computer.
3.
On the computer, confirm the input from the VR-3EX.
Start a program that supports USB video class or audio class, and
check the video or audio input from the VR-3EX.
If necessary, make the following settings on the VR-3EX.
•
Adjust the volume balance of the input audio (p. 35).

3EX by remote control from a computer connected via USB.
VR-3EX RCS can be downloaded from the Roland website
mentioned above.
For more information about operation methods, refer to the

About Remote Control Via MIDI
The VR-3EX also supports remote control by equipment compatible
with MIDI Visual Control.
For information on remote control via MIDI, download and refer to
the “VR-3EX Remote Control Guide” (PDF) from the Roland website

What’s MIDI Visual Control?
MIDI Visual Control is an internationally-used recommended
practice that was added to the MIDI specification so that
visual expression could be linked with musical performance.
Video equipment that is compatible with MIDI Visual
Control can be connected to electronic musical instruments
via MIDI in order to control video equipment in tandem with
a performance.
