Having all RBG LEDs lit red when opening Traktor means that your unit isn't getting a proper MIDI Clock signal from for Twister's Sequencer mapping to work correctly. To ensure it gets the right signal you need to check 3 things.
- Go to the Controller Manager inside Traktor's preferences window and ensure that the IN/OUT ports are assigned to your device (not All Ins) in both "Seq Clip Triggers" and "Seq Deck Controls" instances of this mapping
- Go to the MIDI Clock tab again in the preferences and enable "Send MIDI Clock"
- Click on the metronome icon under the left FX Unit(s) and enable the Play/Pause button.
