About E-MEM Control of External Devices
E-MEM effects can be used to:
• Load, cue, play, and stop DDR clips, and
• Cue, play, and stop tapes in VTRs.
E-MEM Device Control is good for recalling the same clips repeatedly, and for integrating
clips into specific switcher effects. Manual control is appropriate when different clips are
used each time, and when clips are not used in a switcher effect (like rolling a news story
and taking it directly to air.)
For Kayenne systems, E-MEM Device Control operates independently from the manual
controls on the Multi-Function or Device Control Module, but both mechanisms can be
used together. For example, an E-MEM recall can make a VTR cue up, then the module can
be used to roll that tape.
E-MEM External Device Control utilizes events. External device events are different from
other parameters in the K-Frame E-MEM system. Rather than defining a value at a keyframe
and smoothing the transition between keyframes with interpolation, a device event
consists of instructions sent to the external device at the time the cursor passes the
keyframe during an effect run. This is similar to GPI and PBus triggers.
Controlling an external device typically requires spacing the instructions over two or more
keyframes. The space between keyframes allows the device to respond to the first set of
instructions. For example, a DDR or VTR takes time to load and cue before it can play. The
effect must be built so that a play event does not occur until the device is ready, or the
command will be executed late or not at all.
The K-Frame system does not play a DDR or VTR in sync along with the timeline like digital
effects devices controlled by CPL. Instead, the K-Frame system issues a play command then
lets the device manage its own playback. This means that if the K-Frame effect is
lengthened or shortened, the device’s playback may not line up with the effect as intended.
Device playback does not speed up or slow down if the duration of the effect changes.
Configuration
K-Frame Device Control option software must be installed and configured to permit either
manual or E-MEM control of DDRs and VTRs. Sources will also need to be configured as
external devices in Eng Setup.
E-MEM control for external devices is by default assigned to the Misc 16 EXT Master E-MEM
Module enable group button. This can be changed in the User Setups, Suite Prefs, E-MEM
Prefs menu.
• External Devices are configured for control in the Ports & Devices, External
Devices menu. See the Kayenne/Karrera/GV Korona Installation & Service
Manual for more information.
