LTP
An abbreviation of ‘Latest Takes Precedence’. This
defines how a Channel responds to multiple control
levels, e.g. if a cue and a sequence are both
attempting to control one channel. LTP causes the
last requested level to be used.
MIDI
An acronym for Musical Instrument Digital Interface, a
system for connecting various devices (usually
musical instruments) allowing one device to control all
of the others. VENTURA uses a special group of MIDI
commands specifically designed for lighting and
control applications. These commands are known as
MSC (MIDI Show Control).

Palette
The name given to the preset Lamp Attributes for
Colour , Beam and Effects . Initially, the options
contained in the Palette are loaded from the Lamp
Library. These defaults may be retained or modified
by the user.
Pan
Patching
The routing of console channels to output, dimmer or
DMX channels.
Position
The direction in which a light beam is aimed. The
direction is defined by two parameters — Pan and
Tilt.
RAM
An acronym of ‘Random Access Memory’.
Scroller
A continuous roll of different coloured filters (or ‘gels’)
which can be scrolled backwards or forwards (under
the control of an LTP Channel) in order to change the
colour of a light beam. See also Colour Wheel .
A mechanical device which is either ‘open’ in which
case light is allowed to pass unrestricted, or ‘closed’
in which case no light is allowed. It is primarily
intended to provide an instant ‘turn- on’ or ‘turn- off’.
SMPTE
Abbreviation of Society of Motion Picture and
Television Engineers. This is a Timecode standard
which gives a frame rate of 30 frames per second.
Tilt

Timecode
A data signal which contains encoded time
information. It is used by many video and audio
media to allow the synchronisation of different
sources to a common time- base. VENTURA allows
Cues to be triggered when a specific SMPTE frame
count is reached, thus allowing synchronisation of
lighting effects to a backing track or video.
