SMPTE/MIDI Time Modes
This section describes the differences
in options, display formats, operation
etc. when
Time Input
is set to
SMPTE
Time
or
MIDI Time
in
Desk Setup
(see
Playback X Defaults in chapter 3 for
further details).
Memory Triggers
When
Time Input
is set to
Real Time
,
the memory triggers available are
Go
,
Automatic
and
At Time
. If the Trigger is
set to
At Time
the start time is
specified and displayed in the format
hh:mm:ss
.
When
Time Input
is set to
SMPTE
Time or MIDI Time
, the memory
triggers available are
Automatic
and
At
Time
only. If the Trigger is set to
At
Time
the start time is specified and
displayed in the format
hh:mm:ss:ff
,
where ff is frames.
Transition Times
On the Memories screen, the transition
times (delay, fade and dwell times) are
displayed as follows:
When
Time Input
is set to
Real Time
,
the times are displayed in the format
mm:ss.t
where t is tenths of seconds.
When
Time Input
is set to
SMPTE or
MIDI Time
, the times are displayed in
the format
mm:ss.ff
where ff is the
number of frames.
Programming Memories
When programming memories with an
At Time
trigger in SMPTE or MIDI time
modes, the start time is specified and
displayed in hours, minutes, seconds
and frames (see earlier).
This start time is then fixed and can
only be adjusted by the user.
It is possible to specify a start time
which would overlap a previous
memory and to program memories in a
non-chronological order although this
is not recommended practice.
A memory with an
At Time
trigger has
higher priority and will be triggered
when the incoming SMPTE or MIDI
timecode signal equals the
programmed start time, regardless of
the current position in the memory
stack.
Editing Memories
If the start time of a memory is
modified, the duration of a memory is
changed (by altering the delay, fade or
dwell times), or memories are added or
removed from the memory stack - all
other memories with At Time triggers
will not be affected.
Jumps
Jumps can be programmed into the
memory stack in all
Time Input
modes
(see chapter 7).
A memory which is jumped to will only
run immediately if its trigger is set to
Automatic
.
Loops
Loops can be programmed into the
memory stack in all
Time Input
modes
(see chapter 7).
When the desk is in SMPTE or MIDI
mode - the first memory in a loop can
have an
Automatic
or
At Time
trigger.
The
Loop Trigger
is always
Automatic
.
Display of SMPTE and MIDI
Timecode
When the desk is in SMPTE Time or
MIDI Time modes the timecode value
(whether generated internally or
externally) is displayed in the Fade
Status Bar on the monitor screen.
The Override field is replaced by the
Timecode field. The Timecode is
displayed in the format
hh:mm:ss.ff
.
