Let's consider a simple example taking advantage of the potential this ability offers.
Using TriCaster's Macro system, it is easy to take advantage of network connections
to send instructions from TriCaster to 3Play via the Macro system. Such a macro could
actually perform sequential operations on both systems, and be assigned to a shortcut
keystroke or other macro trigger for convenient execution with a single user
interaction.
When both 'parties' to the network 'conversation' have been correctly prepared, as in
this case, there is no need for complicated configuration. TriCaster 'knows' which
network source is connected to its network inputs, and automatically creates the
necessary bi-directional communication channel.
For example, 3Play network outputs typically appear in TriCaster's Network Input
source selectors as something like "3Play(A)" and "3Play(B)". If you select "3PlayA"
as the active source for TriCaster's "Net 1" input, a communication channel between
3Play's A channel and Net 1 is automatically opened. Unique shortcut entries in the
macro identify which Network Input the instructions specified will be directed to.
When examined in TriCaster's Macro Editor, a typical macro entry of this type might
look as follows:
Delay (ms) Shortcut
0
The shortcut "net1" defines which Network Input will be addressed.
Additional entries on the same line constitute an instruction that will be performed
when the macro is executed.

The Value "clip_play" commands the target source to play the currently
selected clip (in our example, the current clip selected on 3Play's channel A)
