UNKNOWN: One or both decks have no usable key.
Independent Key Sync (shift pitch without tempo) needs Master Tempo, which is not enabled. Rate changes still move pitch with tempo.
Headphone cue
This browser cannot send audio to a second output device (setSinkId). The cue is silent: it is never mixed into the master.
Cue is tapped after the channel fader: a deck with its fader down is silent in the cue too.
