QML Mod - 4 channel support on param reset upon song load

I've been getting some success resetting stem parameters on a deck when loading a song. My code works for deck 1 and 2, but I can't get it to work for deck 3 and 4.

I tweaked the resetFocusedStemDeckVolumeAndFilter function using the structure shown below:

function resetFocusedStemDeckVolumeAndFilter(deckId)
{
var defaultVolume   = 1.0;

if (deckId == topDeckId)
  {
  // Set all volumes to maximum
  topStemVolume1.value   = defaultVolume;
  topStemVolume2.value   = defaultVolume;
  topStemVolume3.value   = defaultVolume;
  topStemVolume4.value   = defaultVolume;
  
  
  }
else
  {
    // Set all volumes to maximum
    bottomStemVolume1.value   = defaultVolume;
    bottomStemVolume2.value   = defaultVolume;
    bottomStemVolume3.value   = defaultVolume;
    bottomStemVolume4.value   = defaultVolume;
    
  }
}

I haven't been able to make this work for deck3 and 4, and I think that's because of the topDeckId/bottomDeckId.

I'm working on a dynamic code using declarations as follow:

AppProperty { id: topStemVolume1; path: "app.traktor.decks.1.stems.1.volume" }

AppProperty { id: topStemVolume2; path: "app.traktor.decks.1.stems.2.volume" }

AppProperty { id: topStemVolume3; path: "app.traktor.decks.1.stems.3.volume" }

AppProperty { id: topStemVolume4; path: "app.traktor.decks.1.stems.4.volume" }

AppProperty { id: bottomStemVolume1; path: "app.traktor.decks.2.stems.1.volume" }

AppProperty { id: bottomStemVolume2; path: "app.traktor.decks.2.stems.2.volume" }

AppProperty { id: bottomStemVolume3; path: "app.traktor.decks.2.stems.3.volume" }

AppProperty { id: bottomStemVolume4; path: "app.traktor.decks.2.stems.4.volume" }


function updatePropertyPaths() {

topStemVolume1.path = `app.traktor.decks.${topDeck}.stems.1.volume`;
topStemVolume2.path = `app.traktor.decks.${topDeck}.stems.2.volume`;
topStemVolume3.path = `app.traktor.decks.${topDeck}.stems.3.volume`;
topStemVolume4.path = `app.traktor.decks.${topDeck}.stems.4.volume`;

bottomStemVolume1.path = `app.traktor.decks.${bottomDeck}.stems.1.volume`;
bottomStemVolume2.path = `app.traktor.decks.${bottomDeck}.stems.2.volume`;
bottomStemVolume3.path = `app.traktor.decks.${bottomDeck}.stems.3.volume`;
bottomStemVolume4.path = `app.traktor.decks.${bottomDeck}.stems.4.volume`;

// Update Track Type paths
topDeckTrackType.path = `app.traktor.decks.${topDeck}.track.content.stem_available`;
bottomDeckTrackType.path = `app.traktor.decks.${bottomDeck}.track.content.stem_available`;
}


function resetFocusedStemDeckVolumeAndFilter(deckId)
{
var defaultVolume = 1.0;

// Determine if we're working with top or bottom deck
var isTopDeck = (deckId === getTopDeckId(decksAssignment));

// Select the appropriate properties based on top/bottom deck
var stemVolume = isTopDeck ?
    [topStemVolume1, topStemVolume2, topStemVolume3, topStemVolume4] :
    [bottomStemVolume1, bottomStemVolume2, bottomStemVolume3, bottomStemVolume4];

// Reset volume on all channels
for (var i = 0; i < 4; i++)
  {    
  // Set volumes to maximum
  stemVolume[i].value = defaultVolume;
  }
}

enum DecksAssignment {
AC,
BD
}

// Add this to trigger reset when a new track is loaded
AppProperty
{
id: deckLoadedProperty; path: "app.traktor.decks." + deckId + ".is_loaded"
}

onDeckLoadedPropertyChanged:
{
  if (deckLoadedProperty.value) {
  resetFocusedStemDeckVolumeAndFilter(deckId);
  }
}

Does it look like a promising direction? Or should I look elsewhere?

Thanks a lot for your help!

    This is S5/S8/D2 code you are working on, right?

    To the topic creator: Why are you creating two topics?

    At first glance it looks as if the S5 has already mastered the functions. (TP4)

    Yes, I started working for it on my S5, and now I have an S8 so I'd like to make it work for both.

    Ah, sorry, I guessed wrong in making a different thread. It was a different question on the same topic.

    Thank you for your input, I'll try that although I'm still on TP3.

    Yes, it's best to try it yourself.
    If this is not possible, upload your files.
    but please don't use any that cause an error.
    or read this topic there are some good tips

    Hmm, that dynamic approach doesn't work with my S5. The code Claude.ai gave me could load, but the one I got from Pixel crashed on startup.

    I'm reverting to my qml that works for deck A and B, good enough for most situations.

    S5 StemReset+Key AB.txt

    Sadly, I tried to add those changes to my S8 qml, but those files are very different and that code is just inactive over there.

    It looks like the syntax would be simpler to manage the four decks, but the file structure is so different that I'm not sure how to add my custom qml.

    S8 qml.txt

    I think that those stem param reset are key to anyone that's using stems seriously, so I hope that someone will figure it out.

    If no one comes forward with an S5 by next weekend, I'll take a look at your file.

    edit: Please upload the qml file.
    Preferably one without your changes

    Well, thank you if you can do something.
    Here is the default S5 file:

    S5Deck.qml.txt

    I investigated a little on the S8 side, and it seems that the file is actually in CIS/common/, but I haven't had any success yet.

    Deck_S8Style.qml.txt

    Yes! That code that you shared works both for S5 and S8!
