Live and Blind

Live and Blind are methods to view and edit data in your show files. When you press the

[Live] key, the screen will show you the live display. When you press [Blind], you will see

the blind display. In either case, you may use the [Format] key to alter how the data is

displayed (see

Using [Format], page 58

).

When in Live, the data displayed represents the data being sent from the console at that

moment. In other words, the parameter data that is “live” on stage. When you edit data in

live, those changes will become active and visible on stage as soon as the command line

is terminated.

When in Blind, the data displayed represents data from the record target you choose to

view (cues, presets, palettes, and so on). When you edit data in Blind, changes will not

automatically appear on stage, since the data you are modifying is not live. This is true even

if the record target you are modifying is active on stage. It is possible to play a cue in Live,

then switch to Blind and edit that cue in blind without affecting levels on stage. Edits in Blind

do not require a [Record] command to be stored. They are considered stored when the

command line is terminated. Any display that is not the Live display is considered Blind, and

the Blind LED will be illuminated. For example, if you open patch, the blue LED on [Blind]

will be lit to show that you are in a Blind display.

HTP vs. LTP

HTP (Highest-Takes-Precedence) and LTP (Latest-Takes-Precedence) are terms used to

define the output of a channel parameter that is receiving data from multiple sources. In

HTP, the highest level of all sources will be executed. In LTP, the most recent level received

will be executed. Cue lists can operate as HTP or LTP for intensity parameters only. Non-

intensity parameters (NPs) are always LTP. Submasters can operate as HTP or LTP for

intensity. The default is HTP. Eos’s default cue list setting for intensity is LTP (see

HTP/

LTP, page 237

).

HTP

HTP is only applicable to the intensity of a channel. HTP channels will output the level that

is the highest of all inputs. HTP channels are also referred to as “pile-on”, because as

control inputs are added (for example - you may bring up cues and multiple submasters that

all have the same channel recorded at various levels), the system calculates which input

has the highest level for that channel and outputs that level for the channel. As control

inputs are removed (you pull some of the submasters down to zero), the console will adjust

the channel level, if required, to the highest remaining level.

LTP

LTP is applicable to any parameter of any channel. LTP output is based on the most recent

move instruction issued to the channel parameter. Any new values sent to the channel will

supersede any previous values, regardless of the level supplied.

Eos determines the LTP value for a channel, which is overridden by any HTP input values

that are higher than the LTP instruction. This is then finally modified by manual control.
