Practical Use of the PR-50
8.
Go to "Video Mixer Control" and use "VFX1 Control" to set the MIDI message that controls the
video mixer's effects.
(Controls are not accepted via MIDI when this is set to [OFF].)
The effects are controlled with the selected MIDI message.
A MIDI value of 0 corresponds to "OFF," and values 1 through 127 correspond to "ON" (or to changes
in the parameter if the effect has variable parameters). Set "VFX2 Control" through "VFX4 Control" in
the same way.
Some video mixers may not support this feature.
9.
Go to "Color/Brightness Control" and use "Output Fade" to select the MIDI message that
controls the fade applied to the video mixer's final video output.
(Controls are not accepted via MIDI when this is set to [OFF].)
The fade applied to the video mixer's final video output is controlled by the selected MIDI message.
The range of MIDI values, 0–64–127, corresponds to the range of the minimum to maximum values
for the parameter.
You can use the box on the right side to select the polarity of the control. Select "+" to set the parameter
targeted for MIDI control to [0: normal playback – 64: 50% white fade – 127: 100% white fade], "-" for
[127: 100% black fade – 64: 50% black fade – 0: normal playback], and "+/-" for [-127: 100% black fade
– 0: normal playback – 127: 100% white fade].
Some video mixers may not support this feature.
This setting is shared with “Controlling Fades” (p. 87).
10.
To set the latency between the PR-50 and the video mixer, use the "Presenter => External
Latency" and "External => Presenter Latency" settings.
The latency (delay) for operations made from the PR-50 may differ from one video mixer to another.
If video transitions under control from the PR-50 are corrupt, or if unexpected video is seen during
such transitions, then adjust these two values to make video transitions smooth. Delay can also be
applied to input switching on the video mixer, so adjusting this may also be a good idea.
(For information on the V-4 and the V-440HD, refer to “Setting Examples for Edirol Video Mixers”.)
11.
