Would love to be able to disable Stem loading on a double press

Which controller is the above mentioned 'knob' attached to?

Edit: Depending on the answer i can point you to one of two files that you can edit to reinstate the TP3 load function.

Open the file '…\Native Instruments\Traktor Pro 4\Resources64\qml\CSI\Common\ExtendedBrowserModule.qml' in a good coding editor like notepad++.

Find these lines …

  Wire { from: "%surface%.browse.encoder.push"; to: "browser_load_gestures.input" }
  Wire { from: "browser_load_gestures.single_click"; to: TriggerPropertyAdapter { path: "app.traktor.decks." + deckIdx + ".load.selected"; output: false } }
  Wire { from: "browser_load_gestures.double_click"; to: TriggerPropertyAdapter { path: "app.traktor.decks." + deckIdx + ".load_secondary.selected"; output: false } }

… and replace all of them with the following line

  Wire { from: "%surface%.browse.encoder.push"; to: TriggerPropertyAdapter { path: "app.traktor.decks." + deckIdx + ".load.selected" } }

Don't forget to make a copy of the original qml folder before modifying any of its contents.
