Controlling Presenter with MIDI

Using MIDI Devices

Because the items "Video Mixer Control" have been added to the MIDI System Settings (p. 83 in the
PR-50 Owner's Manual), the screen layout and the names of some items have changed.

Using Other Devices to Control Presenter

The feature known as "V-4 Control" in previous versions is now called "Video Mixer Control" and
also supports other video mixers in addition to the V-4. Along with this, some other features have
been added or changed.

Controlling an Edirol Video Mixer

Using a video mixer from Edirol (such as the V-4 or V-440HD) in combination with the PR-50 lets you
control the video mixer using the PR-50. When you do this, you can take the video input to the video
mixer from the external source and work with it as clips using the PR-50. Additionally, you can use
an external MIDI device to control the video mixer's effect settings and fade the final video output.
1.
Using MIDI cables, connect a USB MIDI interface to the PR-50 and connect the MIDI
interface's MIDI OUT to the video mixer's MIDI IN.
For more information about USB MIDI interfaces, refer to p.83.
2.
Input the video output from the PR-50 to the video mixer.
3.
Turn on the power to the PR-50 and the video mixer.
When you're making the connection, first turn on the power to the video mixer, then turn on the
PR-50.
4.
Set the Device ID for the video mixer.
For instructions on how to set the Device ID, refer to the owner's manual that came with the video
mixer.
