Mute
The VCA Mute button controls the mute state of
audio, Auxiliary Input, Instrument, MIDI, and
other VCA Master tracks in a VCA-controlled
group. Muting a VCA-controlled group does not
change the original mute state of slave tracks.
(Mute buttons on slave tracks that were previ-
ously unmuted show an implicit mute.)
Solo
The VCA Solo button controls the solo status of
audio, Auxiliary Input, Instrument, MIDI, and
other VCA Master tracks in a VCA-controlled
group.
• Soloing a VCA Master will implicitly mute
all tracks except its slave tracks, thereby in-
directly soloing the slave tracks.
• Soloing a VCA Master will clear any explicit
solos on its slave tracks, leaving them indi-
rectly soloed, and implicitly mute all other
tracks.
• Explicitly soloing a slave track while its
VCA Master track is soloed will override the
VCA Master solo.
Record Enable
The VCA Record Enable button toggles the
Record Enable status of only those audio, Instru-
ment, and other VCA tracks that have already
been record-enabled individually. You can then
toggle record enable on and off for those tracks
using the VCA Master Record Enable.
To temporarily force all slave tracks to toggle their
record enable status:
■ Alt-click (Windows) or Option-click (Mac) the
Record Enable button on the VCA Master.
TrackInput
The VCA TrackInput button toggles the input
monitor status of only those audio tracks in a
VCA-controlled group that are record-enabled.
You can toggle Input Monitor status for those
tracks using the VCA Master TrackInput button.
To temporarily force all slave tracks to toggle their
input monitoring status:
■ Alt-click (Windows) or Option-click (Mac) the
VCA Master TrackInput button on the VCA Mas-
ter.
Level Meter
On VCA Master tracks, Level meters indicates
the highest level occurring on any of its individ-
ual tracks, not a summed level of all slave tracks.
The channel format of Level meters on the VCA
Master is set according to the channel formats of
its slave tracks, as follows:
• If all slave tracks are the same channel for-
mat (mono, stereo or a multichannel for-
mat), the number of level meters on the
VCA Master track is identical to that of the
slave tracks.
• If the slave tracks are different formats, the
number of level meters on the VCA Master
track is set to one.
Record Enable, TrackInput and Slave
Tracks
When a slave track is record-enabled (the Record
Enable button is lit) or set to Input Only mode
(the TrackInput button is lit), its automation is
temporarily turned off, and its Volume fader is
no longer affected by the VCA Master.
