A_DATA_XP/B_DATA_XP
The DATA_XP gain type result in zero or unity gains. The changeover occurs
instantaneously at a pre-defined point during A/B transitions. Only one
A_DATA_XP and B_DATA_XP should be used in any particular mix. An
example mix file using a stereo data path can be found in the examples
section.
A_XP/B_XP
The A_XP and B_XP gain types are used for the A and B inputs to the A/B
mixer respectively. The gains applied depend on the position and behaviour
of the A/B mixer.
A_CUT_XP/B_CUT_XP
The A_CUT_XP and B_CUT_XP gain types are identical to the A_XP and
B_XP gain types, except that they perform a cut at the midpoint rather than a
fade.
VO1_XP/VO3_XP
The gain types VO1_XP and VO3_XP correspond to Voiceovers 1 and 2
respectively. These apply the preset voice-over level to the assigned input
when that particular voice-over is turned on. This also causes any signal
before that voice-over in the audio path to be ducked to the preset duck level.
If a voice-over gain type is not used in a particular mix then no ducking will
occur in that mix.
VO1_PREVIEW_XP/VO3_PREVIEW_XP
These act in the same way as VO1_XP/VO3_XP but are not sensitive to
voice-over gain, fade-to-silence or duck values.
