fx knob wiring (qml coding)

oviwan

Any ideas what's wrong with this:

Wire { from: "%surface_prefix%.fx.knobs.1" to: EncoderScriptAdapter { onTurn: { ... } } }

Am I using the right knob names/events?

EncoderScriptAdapter only knows onTick, onIncrement and onDecrement.

onTurn is used by KnobScriptAdapter.

EncoderScriptAdapter onIncrement doesn't seem to get called on s4mk3.left.fx.knobs.X

Using KnobScriptAdapter onTurn won't allow Traktor to start

Hmm.

Here is some code that works:

Wire {
  from: "%surface%.knobs.1";
  to: KnobScriptAdapter {
    onTurn: {
      lastActiveKnobProp.value = 1
    }
  }
}

…

Wire {
  from: "%surface%.knobs.1";
  to: EncoderScriptAdapter {
    onTick: {
      if (value < -minimalTickValue1 || value > minimalTickValue1)
        mixerFXAdjust3.value = mixerFXAdjust3.value + (value * rotationScaleFactor1);
    }
  }
}

…

Wire {
  from: "%surface%.browse";
  to: EncoderScriptAdapter { 
    onIncrement: clockBpm.value = clockBpm.value + stepBpm.value;
    onDecrement: clockBpm.value = clockBpm.value - stepBpm.value
  }
  enabled: !shift
}

What value do you want to control with the knob?

oviwan

ButtonScriptAdapter doesn't seem to work at all for me (Traktor won't start). Is that Traktor4 specific?

Neither onTick or onIncrement work with EncoderScriptAdapter on s4mk3.left.fx.knobs.1 or s4mk3.left.knobs.1

No matter what value I try to control, the event handler is not triggered.

EncoderScriptAdapter.onIncrement works for me for %surface%.browse.encoder.turn tho.

Post your code. :)

oviwan

property real b: 0;

Wire { enabled: true; from: "s4mk3.left.browse.preview"; to: ButtonScriptAdapter { brightness: b } }

Wire { enabled: true; from: "s4mk3.left.fx.knobs.1"; to: EncoderScriptAdapter { onIncrement: { b = 1 } onDecrement: { b = 0 } } }

Dunno how to format code…

Encoders are endless knobs, so I doubt EncoderScriptAdapter works with plain knobs like the FX knobs. Have you tried the KnobScriptAdapter example posted earlier?

You're right, I tried this with channel fx.amount without success.

KnobScriptAdapter works :)

oviwan

Traktor won't start if I add: Wire { enabled: true from: "s4mk3.left.fx.knobs.1"; to: KnobScriptAdapter { onTurn: { b = 1 } } }

I tried different values for "from"…

pixel

property int brightnessVar: 0

Wire {  from: "s4mk3.left.fx.knobs.1";
  to: KnobScriptAdapter {
    onTurn: {
      if (value > .50) brightnessVar = 0.0
      else brightnessVar = 1.0
    }
  }
}
Wire { from: "s4mk3.left.browse.preview"; to: ButtonScriptAdapter {
		brightness: brightnessVar;
	}
}

I created an example for you :)

oviwan

Traktor won't start if I add that code. Have you tried it with Traktor 3?

What happens if you define b as int instead of real? You are only using int values in your example.

https://community.native-instruments.com/discussion/comment/199373#Comment_199373

Why are you assigning real values (0.0, 1.0) to an int? ^^

pixel

did you add "import QtQuick 2.0" in your qml file?
If not, it might not work for you.

@Sûlherokhh You're right, but there shouldn't be any errors

oviwan

Changing b to real doesn't seem to make a difference. As soon as I add KnobScriptAdapter to my qml file, Traktor fails to load.

KnobScriptAdapter may indeed be new to Traktor 4. Only X1Mk3 and Z1Mk2 use it.

How about this?

MappingPropertyDescriptor {
  id: CounterProp;
  path: "mapping.state.left.counter";
  type: MappingPropertyDescriptor.Float;
  value: 0.0;
  min: 0.0
  max: 1.0
}

Wire { from: "s4mk3.left.fx.knobs.1"; to: DirectPropertyAdapter{ path: CounterProp.path } }
