Is that the case? Or does the event need to be known and programmed?
e.g., I have reconfigured a CMC-TP and a CMC-FD to send and receive various midi messages, and the touch faders update. If someone knows what channel and command to use then they can create an implementation.
Locked, in my view would mean that even if a person knew the right commands to send to the unit it would still not work.
