Introduction 7

Live and Blind

Live and Blind are methods to view and edit data in your show files. They are also

considered to be specific displays within Ion. 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 38)

When in Live, the data displayed in the live display 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. Changes in Live therefore affect the live output from the

console.

When in Blind, the data displayed in the blind display represents data from whatever 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.

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.

Submasters are only capable of controlling HTP intensities. Cue lists can operate as HTP or LTP for

intensity parameters only. Non-intensity parameters (NPs) are always LTP. Ion’s default cue list

setting for intensity is LTP (see HTP/LTP, page 171).

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.

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

higher than the LTP instruction
