Yep, and you clear individual parameter settings by holding the trig key whilst pushing/clicking the knob of a particular parameter that you want to clear.
For example: if you had a parameter lock on the filter cut off, and a parameter lock for the resonance, and yet another parameter lock for distortion, but wanted to clear the p-lock setting for just the resonance, you would hold the trig key and push the knob for the resonance parameter, and the setting would be cleared.
