Control Values

Control Values connect named controls on a QSC Q-SYS or Symetrix DSP core — audio levels, source selectors, mutes — to the DMX Core 100’s own control points. Once defined, a Control Value can be driven from a control surface knob, a custom menu slider, an input trigger, a timeline track, or a script — with the current DSP state reflected back everywhere.

A typical install: a wall fader (via input trigger), a Stream Deck knob, and a custom menu slider all bound to the same VOL1 Control Value, which maps to a Symetrix volume controller. Move any of them — or change the volume from the DSP side — and every surface updates.

Web UI

Control Values are managed under Control & Integrations > Control Values. The DSP connection itself is configured under Control & Integrations > Plugins — see Q-SYS & Symetrix.

Kinds

Kind	Holds	Example
Level	A continuous 0–100% value	Room volume
Selector	One choice from a list	Source select (Input A / Input B / …)
Toggle	On or off	Mute

Settings

Each Control Value has:

• Code / Short Name — the identifier used in menus, triggers, timelines, and scripts (e.g. VOL1)
• Kind — Level, Selector, or Toggle
• Plugin — Symetrix or Q-SYS
• Controller Number — the controller number assigned in SymNet Composer (or the named control in Q-SYS Designer)
• Status Controller (optional) — read state from a different controller than the one written to. Use when a trigger writes one control but the real state is reported by another (e.g. a relay or wall panel)
• Step Size — how far Up/Down operations move a Level (default 5%)
• Linked Mute Controller (optional) — a mute controller linked to this level, with an optional Unmute On Level Change behavior

Operations

Anything that targets a Control Value can perform:

• Set value — a level percentage, a selector choice, or on/off
• Up / Down — step a Level by its step size, or move a Selector through its choices
• Toggle — flip a Toggle kind (or a linked mute)

Value-mode input triggers feed their numeric payload straight into a Level — optionally shaped by a transform script for response curves and dead zones. Timed ramps fade a level smoothly to its target instead of jumping.

Live State Everywhere

The current value is shown in the Control Values list and is pushed to every bound surface: LED colors on keypads, knob displays on a Stream Deck, OSC feedback to TouchOSC layouts, highlight states on custom menu items, and dmx.controlValue.get()/status() in scripts.
