VCA Master Tracks
VCA Master tracks emulate the operation of
voltage-controlled amplifier channels on analog
consoles, where a VCA channel fader would be
used to control, group, or offset the signal levels
of other channels on the console.
VCA Master tracks do not pass audio, so they do
not have inputs, outputs, inserts or sends. A Mix
group is assigned to a VCA Master track, which
appears in the VCA track’s Assignment selector.
The controls of the tracks in that Mix group,
called the slave tracks, are modified by the con-
trols on the VCA Master.
Creating VCA Master Tracks
To add a VCA Master to a session:
1 Choose Track > New.
2 In the New Tracks dialog, do the following:
• Select VCA Master from the Track Type po-
up menu.
• Select the timebase (Samples or Ticks) from
the Track Timebase menu.
• Enter the number of new tracks.
• Click Create.
VCA Master Track Controls
The controls on a VCA Master track affect the
corresponding controls, listed below, on the
slave tracks in its assigned Mix group.
VCA Slave Track Controls and Group Behavior
When a group is assigned to a VCA Master, the
controls on its slave tracks, by default, do not
follow any grouped behavior that may be set in
the Attributes page of the Groups dialog. This is
standard behavior for VCA operation. However,
slave tracks can be set to follow group behavior.
See “Allowing Grouped Behavior of Slave Track
Controls” on page 60.
Volume
The VCA Volume fader controls the Volume
fader on audio, Auxiliary Input, Instrument,
Master Fader, and other VCA Master tracks in a
VCA-controlled group. (Volume faders on MIDI
tracks are not affected.) Volume faders on slave
tracks move to show the composite level, or the
level on each track resulting from the contribu-
tion of the VCA Master Volume fader.
