the channel number box. Adding or removing a channel from the channel group
does not change the selection state of the channel.
To select the channels in the channel group,
Ctrl-click
on the
ch
channel heading. (All other
channels will be deselected.) Repeated
Ctrl-clicks
on the heading will toggle the members
of the channel group on and off. To set the channel selection to the
compliment
of the
channel group (i.e., the channels that are not in the group)
Alt-click
on the
ch
channel
heading. Repeated
Alt-clicks
on the heading will toggle this complementary set of channels
on and off.
Channel recording state
The buttons labeled
R
and
S
stand for record ready and record safe. These buttons will
appear only when a channel is unlocked (see the next control). Clicking on the column
heading sets all the unlocked channels to that recording state. One of
R
and
S
is always
steadily illuminated, but not both. One button may be illuminated while the other one blinks,
indicating that the channel has been armed for a transition. The transition may occur when
the transport starts moving (in untriggered recording mode) or when the record trigger is
pressed (in triggered recording mode).
Section 2.8
describes the entire recording process.
Channel lock
When a channel is locked it is impossible to record on it; its recording mode is forced to safe
and its Ready/Safe buttons are hidden. The lock can only be changed when the transport is
idle. Clicking on the lock icon toggles the lock state of a channel. Clicking on the column
heading
L
first forces all the channels into locked state (if necessary), subsequent toggles
switch the lock state on all channels. Locking channels permits the system to assign the
available disk recording space to only those channels that need to record.
Peak Level Meter
The peak signal at each channel's monitor source is displayed in a horizontal meter. The
metering parameters (decay constant and headroom) can be adjusted in the metering tab of
the preferences window. Headroom is measured in dB between threshold and maximum
signal value. When the signal is above the threshold the meter turns red. The metering data
can also be displayed in the channel rows during playback (see §
2.16.2
).
Track display mode
A group of ingredients assigned to the same channel is called a track. Sometimes ingredients
overlap. (The Sonoma editor can mix two overlapping ingredients in real time on every
channel.) The ingredients in a track can be displayed two ways. In overlapped mode all
ingredients appear in the same row so overlapping ingredients actually overlap. In
alternating mode the ingredients in a track occupy two rows; ingredients are placed in the top
and bottom rows alternately so that the overlapping material is lined up on adjacent rows.
The default mode is overlapped. To switch modes, click on the overlapping ingredient icon.
Clicking on the
T
column heading toggles the ingredient track display mode on all channels.
Channel height
Regardless of the track display mode, the height of ingredients (and the rows in which they
appear) can be large or small. Small is the default. To change the channel height click on the
single ingredient icon. Large channel height is useful for viewing ingredient waveforms at a
higher resolution. Clicking on the
H
column heading toggles the channel height on all
channels.
