Controller lights up but controls do not respond
These are general checks, not model-specific compatibility certification. Start at low volume and change one setting at a time.
Check in order
- Power does not prove data recognition. Use a data-capable cable and the equipment computer USB port.
- For rekordbox, check supported hardware and PERFORMANCE mode. EXPORT serves a different purpose; LAN alone does not guarantee controller operation.
- Close other DJ apps and check software-control/MIDI/HID mode and deck number against the manual.
- If another good cable and port do not help, check OS device recognition, licensing and supported-hardware requirements.
- If unresolved, use the support note below to record hardware, OS/app versions, last responding meter, tests and outcomes for official support.
I found a difference from a working path/track
- Change one candidate at a time; retain the working configuration and compare the same track.
Still happens / cannot compare yet
- Do not assume hardware failure or a purchase requirement. Follow the checks; record unavailable tests as unverified.
If unresolved
Record hardware models, OS/app versions, the last responding meter and test outcomes for official support. Do not infer hardware failure or a purchase requirement from unverified checks.
