Ross Video XPression GPO Control
Overview
CrossOver Setup
The Hagstrom KE-USB36 is a 36 GPI to USB Keyboard Encoder
that allows the CrossOver™ Multi-Definition Live Production
Switcher to use GPI output triggers to control the XPression™
Sequencer through keyboard commands. Using the Hagstrom KEUSB36, any key found on a standard north american keyboard and
mouse (including movement) can be generated with GPI outputs
from CrossOver. This allows the use of Hotkeys on the XPression
Sequencer to perform Reads, Advancements, Take Offline and even
move the Item bar in the sequencer. Additional commands such as
Clear Channel is available by enabling the Shift, Alt, and Ctrl
commands that can be added as modifiers to the Keystroke on a GPI
by GPI basis.

XPression Setup
To control XPression from CrossOver, XPression must be running
with the Sequencer having focus.
A preview channel can be set up on XPression using a virtual frame
buffer. As you move through the list, the virtual frame buffer
displays the preview frame of the Take item. This is rendered in real
time and will display all of the information Pixel Accurately before
taking it to air.
Switcher Control Interface
From the switcher, you can trigger a GPI output manually using the
pattern buttons on the CrossOver control panel, or automatically
using the RlClip button in the transition area.
Manually Triggering a GPI
1. Press and hold the NEXT button.
2. Press the pattern button corresponding to the command you want
to send to the Ross Video XPression.
Using the Roll Clip Function
1. Select the video source button for the video channel on
XPression that you want to play.
2. Toggle the RlClip button on, on the transition area.
3. Perform the transition. CrossOver will trigger the GPI to tell
XPression to take the currently highlighted take ID online, wait
for the pre-delay (Predly), and then perform the transition.
