To remove the parameter locks of all tracks while LIVE RECORDING mode is active, press and hold [FUNC] + [CLEAR]. Sound locks will, however, not be erased.
Press [NO] + one (or several) of the [TRIG] keys to erase a sequence of recorded trigs on a specific track (or on several tracks) in time with the sequencer, i.e. all steps reached on the pattern playing will be erased until the keys are released. Sound locks will not be erased.
You can also remove specific parameter locks in real time by pressing [NO] while pressing the DATA ENTRY knob corresponding to the parameter that will be removed.
I think this is what you’re looking for? It’s on page 33 
You can also hold down the trig you want to clear automation from and push down the encoder to reset each changed value. This is a bit tricky the frist few tries and is more work if you want all automation to be cleared but very useful if you only want 1 parameters you automated to be cleared. You have to press it quickly without rotating the encoder.
