Hello Fraser,
Welcome on the forum.
What you look for is a software takeover, a setting some people like and some other dislike, as you must move your hardware fader up to its software position to gain the control over the function your fader is supposed to control.
1) To activate the software takeover on the pitch fader in Traktor,
- load the DJControl Jogvision mapping,
- go in Traktor > Preferences > Controller Manager,
- in the Assignment Table, look for Tempo Adjust
- load the first Tempo Adjust, in Deck A, and, below "Device Mapping", and "Mapping Details", in the area "Fader / Knob", check the field "Soft Takeover"
- load the second Tempo Adjust, in Deck D, and, below "Device Mapping", and "Mapping Details", in the area "Fader / Knob", check the field "Soft Takeover"
- Close the preferences: the software takeover is activated.
- In "Hercules equipment in use", please check your Dj controller, DJControl Jogvision,
- In "Software in use", check your DJ software, Traktor
- In "Describe your equipment": describe your computer brand and model, CPU, quantity of RAM, version of Windows or Mac OS, version of DJConsole Series driver package, the version number of Traktor Scratch Pro.
If you do not complete this information, forum readers do not see your Dj gear & soft at first sight, which means most will not read your message.
