Example – Controlling 3Play

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 AirSend 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 prepared using the AirSend API, 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 “3Play(A)” as the active source for TriCaster’s Net 1 input, a communication channel between 3Play’s A channel and Net 1 is automatically established. 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:

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)
  • The Key 1 entry “speed” sets the playback speed to the value which follows next on the line, “.5” in our example. This will cause playback to occur at 50% speed.

It is entirely possible to create more complex macros that combine AirSend commands of the sort just mentioned.
