QML: encoder.is_turned

What's the code you are using for live deck play button look like?

Try this:

Wire { enabled: active && deckType == DeckType.Live; from: "%surface%.play"; to: ButtonScriptAdapter { brightness: 0.0; onPress: play_pause() } }

Brightness can be any value between 0 and 1. You can use any numeric variable (including booleans) in place of the number, like for example ' brightness: deckPlayingProp.value '. If you use it on a button with several RGB values available, you can also add in for example ' color: "Blue"; '.

If you are sharing data in the form of variables, you can do it like this:

S3deck.qml

Module
{
  id: module
  property bool active: false
  
  property bool shift: false
  property string surface: ""

  property int deckIdx: 0

...

 //------------------------------------SUBMODULES------------------------------------------//

 S3Transport
 {
   name: "transport"
   surface: module.surface
   deckIdx: module.deckIdx
   active: module.active
   shift: module.shift
 }

S3Transport.qml

Module
{
  id: module
  property string surface: "" // e.g. "s4mk3.left"
  property int deckIdx: 0 // Traktor deck 1..4
  property bool active: false
  property bool shift: false

...

You can also use Traktor's global variables and assign their values as well as manipulate them locally like this:

 AppProperty { id: deckPlayingProp; path: "app.traktor.decks." + deckIdx + ".play"; }

and in a different module you can define it (if you like) with a different name, pointing to the same global variable.

AppProperty { id: deckPlayingDifferent; path: "app.traktor.decks." + deckIdx + ".play"; }

Then you can use 'deckPlayingProp.value ' or 'deckPlayingDifferent.value ' directly somewhat like a pointer.

How did it go?
