What are the CueServer 2 Playback Modes?

CueServer 2 playback faders (Playbacks) are responsible for maintaining active channels, cues and presets. The number of available playback faders can vary from one to thirty-two, depending on the number of currently active channels (1,024 by default on the CS-900 & CS-940; 512 on the CS-920).

Each playback also is also assigned a mode. By default, playbacks live in "Merge" mode, however, they can be assigned to 5 different modes. This article will cover each mode and what it's use case/properties are.


Merge

Merge combines a playback's channel values with the previous playback in a Highest Takes Precedence (HTP) manner. The highest value of either the input or the playback is output.

The transformation can be simulated by Photoshop's Lighten layer mode.

Override

Override ignores the playback's input. The output from a playback is simply it's unmodified channel values.

This transformation can be simulated by Photoshop's Normal layer mode.

Scale

Scale multiplies the playbacks channel values with its input values. The resulting output is a scaled version of the input.

This transformation can be simulated by Photoshop's Multiply layer mode.

Pin

Pin passes the input through to the output, where each output value cannot be higher than the playback's value. This is the inverse of the Merge mode.

This transformation can be simulated by Photoshop's Darken layer mode.

Mask

Mask multiplies the inverse of the playbacks channel values with its input values. The resulting output is an inverted scaled version of the input. This is the inverse of the Scale mode.

This transformation can be simulated by Photoshop's Subtract layer mode.
