Mapping something (e.g. loop size/out) to jog wheel

Since i've bought my Traktor S3 i wanted jogwheels LEDs to turn around like on S4Mk3. Your beatcounter mod make me believe it is possible. But i'm not programmer but try to do my best :) All i can made from your mod you can see in a video https://drive.google.com/file/d/1IyS50sYFOKOd57fY9mS0e--_z3EIB6oq/view?usp=sharing

Rotation speed assigned to track bpm*2. There is 8 LEDs around jogwheels and traktor, as i understand, works only with 4 beats. So i've made LEDs to glow in pairs. But it not that i want in my perfect world

Maybe there is a way to make rotation speed as classic turntable speeds 33 1/3 rpm or 45 rpm

Is there way to make LEDs turn like on S4mk3? One by one. I understand that S4mk3 LEDs much more smooth, but as close as it can be.

And i want only light mod - no any control mods.

Hope you can guide me in the right direction

I didn't know there where 8 LED's! Sweet! :)

Can you elaborate? What end result do you want to achieve?

First 6 seconds of official s4mk3 introduction https://www.youtube.com/watch?v=feOVbUHcDyA

Or just light up one LED by one

Not two by two as on my video

And is it possible to invert LEDs? I meen not to light up them one by one but light up them all at once and then light down one by one round and round

Yes, both is possible and more.

My idea would be to devide 4 beats into 8 half-beats. For a smoother transition among the 8 LED's it would look like this:

Half-beat 1 lights up LED 1 and LED 2
Half-beat 2 lights up LED 2 and LED 3
Half-beat 3 lights up LED 3 and LED 4
(etc) ...
Half-beat 8 lights up LED 8 and LED 1

4 beats will still make the LED ring turn around exactly once.

So. I've made inverted spin with 2 LEDs

My scheme is like BEAT - LED

1 - 345678

2 - 125678

3 - 123478

4 - 123456

But half-beat is too difficult for me at this moment

Tried something like

Wire {
   enabled: !loopActive.value && (deckBeat[deckIdx]/2 == 0.5) && (deckScratching || deckPlaying);
   from: "%surface%.jogwheel_ring.3"; to: "turntable.lights" ;
  }

But it do not work

Good to see you are actually trying to adjust the code itself to your liking.

As you could see in the file, i have marked a whole section to get the beats and the LED's right. This is my take on the updated section. I will point out a few things at the bottom, but here is the whole thing:

 //-----------------------------------Jogwheel Beatcounter LED------------------------------------//

// AppProperty { id: deckTypeProp; path: "app.traktor.decks." + deckIdx + ".type" }
 AppProperty { id: deckElapsedTime; path: "app.traktor.decks." + deckIdx + ".track.player.elapsed_time" }
 AppProperty { id: deckGridOffset; path: "app.traktor.decks." + deckIdx + ".content.grid_offset" }
 AppProperty { id: deckMixerBpm; path: "app.traktor.decks." + deckIdx + ".tempo.base_bpm" }
 AppProperty { id: remixBeatPos; path: "app.traktor.decks." + deckIdx + ".remix.current_beat_pos" }

 readonly property var deckBeats: deckTypeProp.value != 1 ? (((deckElapsedTime.value * 1000 - deckGridOffset.value + 10) * deckMixerBpm.value) / 30000.0) : parseInt(remixBeatPos.value) * 2

 readonly property var deckBeat: (deckBeats < 0.0) ? (8 - (parseInt(Math.abs(deckBeats) % 8))) : parseInt(Math.abs(deckBeats) % 8) + 1

 WiresGroup {
   enabled: !gridAdjustEnableProp.value && module.active
   Wire {
     enabled: !loopActive.value && ((deckBeat == 8) || (deckBeat == 1)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.1"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 8) || (deckBeat == 1)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.1"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 1) || (deckBeat == 2)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.2"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 1) || (deckBeat == 2)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.2"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 2) || (deckBeat == 3)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.3"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 2) || (deckBeat == 3)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.3"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 3) || (deckBeat == 4)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.4"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 3) || (deckBeat == 4)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.4"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 4) || (deckBeat == 5)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.5"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 4) || (deckBeat == 5)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.5"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 5) || (deckBeat == 6)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.6"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 5) || (deckBeat == 6)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.6"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 6) || (deckBeat == 7)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.7"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 6) || (deckBeat == 7)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.7"; to: "loop.active" ;
   }
   Wire {
     enabled: !loopActive.value && ((deckBeat == 7) || (deckBeat == 8)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.8"; to: "turntable.lights" ;
   }
   Wire {
     enabled: loopActive.value && ((deckBeat == 7) || (deckBeat == 8)) && (deckScratching || deckPlaying);
     from: "%surface%.jogwheel_ring.8"; to: "loop.active" ;
   }
 }

As you can see, i've thrown out a lot of the code that measure the beats of ALL decks at the same time because i've given up on aligning this with master beats. So, this is the reduced code.

Every ring LED has two wires, one for deck colour, one for loop colour. The first line (enabled: ...) shows under which condition the LED lights up. The beat counter will also now count 8 half beats. When it says '((deckBeat == 7) || (deckBeat == 8))' it means, when the beatcounter# is 7 or 8 the LED lights up. If you want it to be inverted, you have to negate it with a '!' symbol in front. In this case, instead of this:

enabled: loopActive.value && ((deckBeat == 7) || (deckBeat == 8)) && (deckScratching || deckPlaying);

it will have to look like this:

enabled: loopActive.value && !((deckBeat == 7) || (deckBeat == 8)) && (deckScratching || deckPlaying);

so, all instances of ((deckBeat == X) || (deckBeat == Y)) need to be !((deckBeat == X) || (deckBeat == Y)).

Hope this helps.

@Sûlherokhh

Thank you very much for the detailed explanation!

I like to understand how any mechanism works so there will be my homework for this evening

I will tell you the results

The latest LED upgrade to the scratch mod, using 8 LEDs turning to the beat (at half beat jumps):

S3DeckScratchMod5.zip

https://community.native-instruments.com/discussion/comment/90329#Comment_90329

The NotScratchJustLED mod, with inverted colour turning:

S3DeckLEDModInverted.zip

Please test away and give some feedback. Don't have an S3 at home to test (I'm testing using my S4Mk3 and the 8 performance pads as placeholders).

Unfortunately this version do not work. Here is video https://drive.google.com/file/d/1kOjmzRl-KMBDH1vwkE3ESjpbEKoCaMFf/view?usp=sharing

VityaT · August 2023

Stop.

My previous post was about S3DeckLEDModInverted.zip

Just tried S3DeckScratchMod5.zip and it works great

Here is video https://drive.google.com/file/d/1-4Q8ZbGEz8xaepHDcoMa1kVr71B0Zlyo/view?usp=sharing

Will analyze your code tomorrow

Great! Thank you again!

Sûlherokhh · August 2023

Thanks for the video. I'll have a look what made the inversion mod not work. And you probably don't want the scratch mod version. Or do you? :)
