Make Null In Blind
When applied in Blind, {Make Null} can be used to mask instructions in a cue after it has already been
stored. A {Make Null} instruction can also be applied to channels/ parameters in palettes, presets,
and submasters, thereby removing the data from the target entirely, in the same way that [At]
[Enter] does.
When applied to channels/ parameters in cues, {Make Null} doesn't remove the data from the cue, it
simply makes it unavailable for playback. It has the same effect on move instructions that it has on
tracked values.
Some examples of using {Make Null} in Blind are:
[Color Palette] [1] [Enter] [3] {Magenta} {Make Null} [Enter] - removes all magenta parameter
data for channel 3 from color palette 1.
[Preset] [5] [Thru] [9] [Enter] {Intensity} {Make Null} [Enter] - removes all intensity data for all
channels in presets 5 through 9.
[Cue] [8] [Enter] [2] [Thru] [7] {Make Null} [Enter] - nulls all data for channels 2 through 7 in cue
8.
[Cue] [9] [Enter] {Intensity} {Make Null} [Enter] - nulls all intensity data for all channels in cue 9.
In the cue scenarios above, {Make Null} differs from using [At] [Enter] in that instead of allowing val-
ues established in previous cues to track in, {Make Null} both restricts the recorded data from playing
back and prevents other values from tracking in. Therefore, if the cue were executed as an out-of-
sequence cue or asserted, no data would play back or track in for any nulled values.
Release
Release is an extension of the {Make Null} command in Blind. When Release is used, it behaves like
Make Null, but it also releases the channel and parameter data to its background state, if one is avail-
able, or fades out the intensity instead.
Release can be used to mask instructions in a cue after it has already been stored. The data is not
removed from the cue.
Release is applied in Blind by using the {Release} softkey or by using the [Release] hardkey.
[Cue] [3] [Enter] [2] {Release} [Enter] - releases all data for channel 2 in cue 3.
[Cue] [2] [Enter] [3] {Color} [Release] - releases the color data for channel 3 in cue 2.
Note:
move instruction happens.
When release has been applied, the released content will display in gray with a R in Blind.
A Release flag will also appear in the Playback Status Display and the Cue List Index.
