As we cannot guarantee suitability of third-party MIDI drivers for TriCaster use, it’s good to know that a
TriCaster Restore operation will restore normal operation if a driver you install has unintended
consequences.
MIDI can be useful in many, many ways. Too, a wide variety of MIDI software and extensions are available
for other devices. These can be used to create unique custom TriCaster control alternatives.
For example, the mockups below depict custom iPad

interfaces (created using third-party iOS

apps)
providing wireless control over TriCaster’s Publish features (Figure 21-65) and DDRs (Figure 21-66).
Countless other possibilities exist, too, of course.
SECTION 21.9 GPI CONTROLLERS
GPI, or General Purpose Interface, is long serving analog control signal system based on simple contact
closure. GPI inputs and outputs are very common on professional production equipment.
The macro system in NewTek live production devices can take advantage of intermediary devices, such as
the eBOX™ network/GPI hardware interface from JLCooper Electronics, to support both GPI signal input and
output.
CONFIGURATION
For an external GPI device to communicate with a NewTek live production system, it must be manually
defined by text entries in the file named gpi_setup.xml. This file can be located in the directory shown below
as appropriate for your product:
