Enhanced AB Mixer Controls
Various additional commands for controlling the Easysound AB audio mixer
have been added to support Presmaster functions. These are documented
here.
Audio AB Position ja
Directly sets up the ‘position’ of the AB mix fader. Used for T-bar control of
AB mixer.
CMD Param_1
ja %03x Mix position. 0 = Fader at B,
512 (or 0x200) = Fader at A
Audio AB Mix Mode jb
Switches between audio cross-fades and audio v-fades.
CMD Param_1
jb %01x Fade mode
0 = X-fades, 1 = V-fades (through
silence)
Audio AB Asymmetric Transition jc
Use this to perform an asymmetric audio transition (such as a V-fade) with a
single call.
Rate 1 defines the duration of the first half of the fade (time take to reach the
midpoint), while Rate 2 is the time from the midpoint to completion. Both
rates are measured in fields. Note, only Rate 1 is used if not doing a V-fade.
CMD Param_1 Param_2 Param_3
jc %1x Direction. 0 = To A,
1 = To B
%03x: Rate 1 in
fields
%03x: Rate 2 in
fields
